ex post facto partition rearrangement

right now i decided to install wine


however.. i am concerned about my 67% utilization

also.. i am feeling concerned about my "/" only subpartition configuration  i am scared to grow
my partition.. umm.. sysinstall doesn't exactly give me confidence.. if i select a partition i guess
it lets me edit the size.. but it is a free edit box i can make it bigger or smaller

maybe this is in grog's book

oh.. i fergot.. you can see above ad0 has at least two partitions of 11GB and 9GB.. the actual
disk is 60GB

to try to clarif myself.. say you are supposed to have a small root partition.. this stops crash..
statistically, it seems to me.. that my dual boot freeBSD might help a lot with that.. but maybe not
maybe i should have small root subpartitions on each..

well.. i guess i am not that far off grog's recommendations.. 4-6GB root plus /home

i dunnno

maybe i should have a /usr  grog doesn't thinkso

i dunno..

i _am_ feeling like growing my freeBSD 6.0 partition though
Best if you separate at least /var /tmp /usr and /, as automatic partitioner does, BUT make / /var and /tmp 1G or so in size, so they do not become too small, and be sure to keep automatically set swap partition
/home is link to /usr/home , if you have more users than you, you may want to use separete partition, but i assume it is yet not the case.

Only reason to split is that / suffers badly from soft dependency option, which in turn makes fsck always succeed, but at the price that some changed files may be lost over reboot ( not very suitable for filesystem with bootup config files)

In addition starting from FreeBSD 5 /dev is configured automatically, so you do not have to worry about it

Yet another reason is that you can set mount options for example that /tmp or mail spool or some chroot directory cannot contain suid programs, which evil hacker can abuse to hack your system. I think OpenBSD does set this for quite some time, and not for no reasons.
You cannot resize partitions without heavy disk editing and archiving/restoring filesystem contents. Some commercial unixes do allow this, sometimes with help of Veritas filesystem software.

is /tmp for swap?  because i have a whole other partition (not subpartition ) ad0s3 for that

i was told i could "grow" partitions relatively easily.   unless you are going to tell me i should really
revert to 5.4 on a full time basis becuase that is the only way i can see my SD card then i think i want to grow my
ad0s1 partition now.
David PiniellaCommented:
/tmp and swap are different. tmp is for temporary storage -- programs might need to put stuff there (lockfiles etc) -- and swap is for paging to disk when RAM is full. If you have multiple disks, and your server is doing a lot of disk writes/filling up RAM, it often makes sense to put a seperate swap partition on each disk
kayveyAuthor Commented:
i made an extra partition and it is shared between my two bootable partitions.. i thought that
was sorta efficient but the reason i did it is sort of related to my question here..  i was afraid to
mess with my exsisting operational partitions so i made  a new one.. it werks fine..

anyhoo.. i think i am feeling okay about my subpartitions but can someone please tell me
how to grow my partition?
6.x is too extreme for now.
5.4 may not change matters for your SD cards probably, but at least everything else will work as expected.

Growing partitions id very complicated matter, command for this is growfs, but you have to add extra space after end of partition, easy only under vinum , which in turn is not very stable yet.
David PiniellaCommented:
in the end i think you're better off backing up what you want and reinstalling/repartitioning. in any case you want to backup, cos growing the partition can mung up your data.

i am on 5.4 right now.. since both my 5.4 and 6.0 see each other's partitions.. could i grow
the 6.0 partion while logged onto the 5.4?  would that be an easy way to do it?

kayveyAuthor Commented:
also.. i don't like the sound of this solution.. i have a freekin 60GB HD i want to start using more real estate
kayveyAuthor Commented:
wooptie do make clean has been running for an hour and i am at 70% utilization instead of 71%

i have more real estate here can somebody walk me thru growing my file system? what about growing
one filesystem's root by booting from the other?  shouldn't that be a good way of growfs without
having to backup and reinstall?  i seriously am not comfortable with reinstalling my OS.  i never installed
them in the first place.  

  again:       one HD  60GB  4 partitions plus unused real estate

      -11GB bootable / for freeBSD 6.0 mounted on /mnt-for-6.x when booting from freeBSD 5.4 70% utilized as seen by df command
      - 9 GB bootable / for freeBSD 5.4 mounted on /stable when booting from freeBSD 6.0  20% utilized as seen by df command
      - 1GB   swap space used by both of the above bootable partitions
      - 10GB MSDOS partition that i marked bootable but haven't successfully installed MS on
      -   whatever's left from 60GB is completely unused i guess around 22GB
David PiniellaCommented:
save your java files somewhere temporarily; your home dir or a new dir that you make jsut for that and then do a make distclean in /usr/ports. yes, it takes a while. incidentally, installing MS anything will likely overwrite your MBR. I suppose you could make your extra 22 gigs a data mount (format it, mkfs a UFS slice on it and then mount it as /storage or /data or something. Then both FreeBSD installs can use it. (MS won't read it, I think, but I'm not sure...it'd surprise me if any DOS or Windows flavor had UFS support.)
kayveyAuthor Commented:
i already thought of a "data mount" but i didn't like the idea because it is looking
like i might need more space to install more programs


okay rtfm growfs
kayveyAuthor Commented:
i have to say.. make clean in /usr/port was some freeking irritating advice, i am sorry to say..

it has been running for hours and it has freed up a couple hundred megs, tops..


i guess i wanted the freeking inodes anyway.

i can growfs, but i have to do it logged onto freeBSD 5.4  just umount /mnt-for-6.x

i can't growfs on a mounted filesystem, so i can only grow the root partition for the version i am not running.
therefore, if i boot onto freeBSD 5.4 i can umount the ad0s1a partition (or is it ad0s1?..

         bsdlabel da0s1

     Display the label for the first slice of the da0 disk, as obtained via

         bsdlabel da0s1 > savedlabel

     Save the in-core label for da0s1 into the file savedlabel.  This file can
     be used with the -R option to restore the label at a later date.

         bsdlabel -w /dev/da0s1

     Create a label for da0s1.

         bsdlabel -e da0s1

     Read the label for da0s1, edit it, and install the result.

         bsdlabel -e -n da0s1

     Read the on-disk label for da0s1, edit it, and display what the new label
     would be (in sectors).  It does not install the new label either in-core
     or on-disk.

first i have to bsdlabel ad0s1, then i growfs it.. only if i am booted up on freeBSD 5.4  because the OS can't be umounted..

is that the complication yer talking about?

answer yes or no and get the points.

okay freek tha deak..

 i guess i get it  just answer myquestion.....

here is my disk right now:

    ---------------------------------------------------  0
      MBR (must be first)
    ---------------------------------------------------   63
      freeBSD 6.0

    ----------------------------------------------------- 11GB
      freeBSD 5.4

    ------------------------------------------------------- 21GB
      freeBSD swap nonbootable
   --------------------------------------------------------- 22GB
       ad0s4  MSFAT not installed

   ----------------------------------------------------------- 32GB


so if i try to growfs it has to be unfragmented?  is that the deal? i can't add space from 32GB+ to ad0s1 because a slice can only be a
continuous piece?  

therefore.. to accomplish this.. i would first need to create a new slice ad0s5 maybe, and copy all of ad0s2 to that.. if i just copy it all,
will it be installed?   how do i do this?  can you walk me thru this?

i don't know everything rudy did, i don't want to have to retrace his steps by asking you guys, it is way too slow.  i am spending all
day ditzing around with this the summer is getting old, i have an incomplete software engineering project to finish, and i have
to have mico running on this damn thing.

here is what i started to do after logging onto freeBSD5.4 as root, not kayve, so that my home directory is /root not /mnt-for-6.x/usr/home/kayve

What you ask can only be accomplished with careful disk editing.
kayveyAuthor Commented:
then walk me through it.. okay tell me know i absolutely have to reinstall freeBSD?

you think 6.0 will be stable by the end of the summer? i really just need to accomplish this
"pong" project next semester and if 6.0 gets stable enough i could just wipe out the
5.4 partion and append it to 6.0.. that would be easy, no?

what about the idea of spagetti filesystem?  that occurred to me, and i think it is very unix-like..

the thing is.. i guess i would have to reinstall stuff.. i need to analyze where all the disk
space is being used.. like i could create ad0s5 and use it for a /usr mount or something..
but then i would need to reinstall everything on /usr?

i really wish you would be more specific here "careful disk edition" does not really
tell me *@& about how to proceed from here.

the suggest of "/data" mount is clearly not very helpful.. i have filled up major amounts
of space just installing things.  for additional disk space to be useful, it has to fit
my needs.. fine i need to analyze the needs.. right now it looks like /usr

clearly, my main problem is /usr/ports

umm.. a problem might be that i have installed .. let's see.. x11..

so.. umm.. what i feel like would be this:

create ad0s5

mount it on /usr/ports

now.. how to not step on the existing installed /usr/ports?   could i somehow create
links to make sure the existing stuff..

i suppose ad0s5 would have to be mounted something like /usr/ports2

then i could make links (is this symlinks or hard links?) from everywhere in /usr/ports  to /usr/ports2  for any
ports i install from now on so they would be loaded in /usr/ports2 but i would have a link from /usr/ports
to /usr/ports2 so they would install correctly?

if you could, please elaborate _specifically_ rather than these useless general statements that reak of
"its too complicated for you to understand just give up and throw the *@#& puter out the window"
David PiniellaCommented:
it is impossible to just "append" the empty space to an already-created partition; this is why gheist keeps referring to what you want to do as "resizing" -- there's no other way for you to do this.
kayveyAuthor Commented:
what the hell is "growfs" then?  you guys keep giving nonanswers that are not very informative.

what about making hardlinks (or symlinks.. sheesh.. how clear a question is that and no answer?)
to a new filesystem mounted on "/usr/ports2"

obviously building a bunch of ports is what is eating up my disk space and it seems to me
mounting another partion on "/data" is not going to solve that because things need to
be found in the $PATH and fine you adjust it but it is hullaballoo when it is a gigantic
make install with all its approved $PATHs

i'm really getting irritated with this.  i am sick of hearing an answer like "its complicated"  so be
clear and enumerate the complications in a definitive matter.
If you have no valuable data on your disk - burn 5.4  cd form iso image and boot it, rest is pretty straightforward...
kayveyAuthor Commented:
okay.. now let me try to paraphrase what you just said.. please correct me if i am wrong...

1) make a "mirror" (namely an "iso image?" .. i will have to google that to understand the steps)
     i.e. a "copy" (i don't really know the difference between a "copy" and a "mirror" other than
      a "mirror" seems to me to be a copy of something that is posted on an FTP site  in case one
      site is down, ppl can download from the other..   )

2)  the "iso image" is something i end up burning on a cd (good.. this will be an impetus for me to
     learn to burn cd's in freeBSD.. that's covered in my book.. i have confidence that will go
     smoothly, but if it doesn't, it will be a good use of my time because in arizona i will definitely
     be able to use this method of data transfer to remain connected to this place and the professor
     who i am supposed to be learning to program middleware from)

3)   now i will have a bootable CD that will have everything installed from my stable freeBSD 5.4
     version. i will be able to obliterate my ad0s2 partition and let my ad0s1 partition eat it up..
     thereby nearly doubling the size of my ad0s1 partition.. does this mean that ad0s3 will still
     be there and i will have a 13th floor phenomenon missing ad0s2 partition?

4) i will want to recreate the freeBSD 5.4 filesystem on a new partition, ad0s5. i know i am going to
    want to do this based on what i know right now, because i have a knoppix bootable CD and i was
    not impressed trying to run an OS from a CD.. data transfer i am pretty sure (not becuase i looked
    up specs, because i experienced the sluggish feel) of CD is far inferior to HD data transfer.

  now.. a possible hitch (or not).. there are links from  my freeBSD 5.4 to freeBSD 6.0  i guess i feel
  okay about that becuase if i am killing 5.4 i won't be killing my home directory, which resides
  on freeBSD 6.0 (a.k.a.  /mnt-for-6.x/usr/home/kayve when running freeBSD 5.4)   will these links
   still werk when i copy the freeBSD 5.4 back to the new partition ad0s5?  

   so this "iso image" thing.. does it mean i don't have to reinstall everything?
David PiniellaCommented:
I understood gheist's suggestion to be that you reinstall from a 5.4 disk that you burn yourself from an ISO image. "rest is pretty straightforward" == repartitioning is easy when you're reinstalling. to do what you just posted (making an ISO of your currently installed system) is not hard, but it's unlikely that it'd fit on a CD and you certainly couldn't boot from it without some serious reconfiguring (RAM disks and loopback filesystems and the like...)

hardlinks will not work with different filesystems/partitions -- a hardlinked file has to share the inode of the "parent" file, so this is not possible.

if a total re-install is completely impossible for you, I can suggest one more work around, although I honestly don't know how good it'd work for you:

.  make a new disk, format, partition, label, etc
.  make it your /usr/ports2 partition or whatever
.  change your cvsup configs to point all your source to be downloaded there instead of /usr
.  cvsup your ports collection and it should show up there.

I don't recommend that you do that because you can potentially mess up your INDEX and pkg db In Fairly Serious Ways.

growfs is complex and few questions about how to deal with it readily present "yes/no" answers. You probably didn't want to hear that, but that's the way it is. See http://ezine.daemonnews.org/200111/growfs.html for some tips on how to use it. (to condense: the empty space needs to be right after the partition you're growing, you'll want to reboot into single-user, remember there's no man pages in single-user mode so print out what you think you'll need, you'll need to label it before you grow it, etc.)

also, look at the last section in this article: http://www.freebsdwiki.net/index.php/Partitioning_Tips_and_Tricks -- the default FreeBSD install does something similar with /home and /usr/home -- /home is really a link, do a ls -lad against /home sometime to see  it.

it's not straightfoward because i have x and other things rudy did including the netwerk configuration that werks.  the only
way i get a wire is what rudy did.

i would need a DVD to put the 2GB i have on freeBSD 5.4  obviously it is not trivial to "reinstall" not for me.
obviously there is a lot that has been done to have more than doubled what was once on a CD.. maybe it was
largely extraction.
i hate installations.  i am having a hell of a time getting java installed.  i don't want to @*#& things up rudy
is gone and it took us 2 weeks to get me to where i am.. i can't afford the downtime i have to make sure i
have something up and running for my mico project starting in september.

what i don't want to hear _AGAIN_ is ".. growfs is too complex for you never mind.." what i want to hear is
how to proceed.  fine.. i will look at that specific link.. that is obviously a vast improvement over what has been
told to me before.

okay was this what you were talking about?

Use soft links to your advantage!

Don't forget that you can use ln to do really nifty things with your drives and partitions. For example if you've taken the first tip's advice and made a relatively small /usr partition and a very large /data partition, you might want to move the ports tree - which can occupy several gigs of space if you build lots of ports and aren't meticulous about cleaning out old distfiles and work directories - into the larger /data partition. But instead of trying to laboriously fix the entire system so that it looks in /data/ports instead of /usr/ports, what you can do instead is mv /usr/ports /data/ and then ln -s /data/ports /usr/ports - now it looks and works as though the ports tree is still in the default location, but in fact it's operating from the bigger partition!

can i now create ad0s5 and make it /data and mount it and do this procedure and everything will werk right?
Okay, you've got a lot of work ahead of you to get all this sorted out.  But it's doable.  Here is what you should do.

First, /stand/sysinstall --> config --> fdisk.  Create a new partition, 10G in size.  Mount it as "tempdisk".

Second, boot from the 5.4 install CD and select "Fixit mode".  From the command prompt:

# chroot /dist
# mount_devfs devfs /dev
# mkdir /mnt/olddisk
# mkdir /mnt/newdisk

Now we're ready to move your data from your old OS install to this new partition for temporary storage so that we'll be able to clean up your partitioning issues without losing your configurations.  NOTE: we are assuming here that your original "/" was mounted at /dev/ad0s1, and your "new /tempdisk" mounted at /dev/ad0s5 after you did your fdisking.  DOUBLE CHECK THIS!

# mount /dev/ad0s1 /mnt/olddisk
# mount /dev/ad0s5 /mnt/newdisk
# cp -Rpv /mnt/olddisk /mnt/newdisk

This will take a while - probably an hour or two, depending on the speed of your drive and system.  The "v" argument will let you watch filenames go blizzing by so you don't have to worry that your system might be locked up.  Once that's done, we're ready to actually start fixing things.  NOTE: WE WILL BE KEEPING ALL YOUR DAEMONS AND SERVERS AND CONFIGS.  So don't panic at this next step.

Boot from the 5.4 Install CD, and this time, tell it you want to install FreeBSD.  Pick standard installation.  Now this is the scary part, but remember, we saved all your data.  Delete your old ad0s1 partition.  If you don't want to dual boot anymore, delete ad0s2 as well.  Just DON'T delete ad0s5, or whatever your new partition wound up being that you just copied all your data to.  Once you've deleted ad0s1 and maybe ad0s2, select "A" to let FreeBSD automatically size your new ad0s1 to all the space remaining on the drive.  Then select "Q" to proceed to disklabeling.

It will ask you about boot managers.  If you kept ad0s2, select boot manager.  If you didn't keep ad0s2, select none.

Now in the disklabeling section, JUST HIT A.  It will automatically make slices for / /tmp /var /usr and swap, with designations like ad0s1a ad0s1b and so forth and so on.  DON'T GET FANCY HERE.  Just let it do the default.  Hit Q after you've hit A and made the slices.

Now it's ready to start installing.  Again, don't get fancy - what you do here actually doesn't even really matter much, so don't try to do anything funky.  Just pick default options and get through this cleanly, we're going to wipe out the actual OS installation with your old OS anyway.

Once you've booted into your new OS installation, drop to single user mode by typing init 1.  Now you're ready to get all your old data back.

# mount -rw /
# mount -rw /usr
# mount -rw /var
# mkdir /mnt/tempdisk

Again, we're assuming here that the full devicename of the partition you created for temporary storage and copied all your files to was /dev/ad0s5.

# mount -rw /dev/ad0s5 /mnt/tempdisk

Now we're ready to get all your old stuff back.  Some of these steps are likely to take a while.

# cp -Rpv /mnt/tempdisk/olddisk/etc /
# cp -Rpv /mnt/tempdisk/olddisk/var /

Those two probably didn't take too long.  This one's going to be the pokey one.

# cp -Rpv /mnt/tempdisk/olddisk/usr/local /usr

Once that's done, you're ready to reboot again, and now you'll have a normal partitioning arrangement, but everything will be as it was when you left it.  shutdown -r now, and check.  If anything's still not working right, that would be because Rudy did something weird with install locations, and you may need to drop back to single user mode and cp -Rpv /mnt/tempdisk/olddisk/usr / ... but DON'T do that unless you absolutely have to, you'll end up reverting to some things you don't want to from your old installation (assuming it's pre-5.4) if you do.

Once you've satisfied yourself that everything is working fine, go back into /stand/sysinstall and fdisk and delete the ad0s5 temporary partition, and create a new partition that's the size of the entire remainder of the hard drive.  Don't mess with the boot loader (leave untouched).  In Disklabel, create a single slice to use the entire partition, and mount it as "data".

Finally, you have a relatively normal configuration - fairly reasonably sized /, /usr, /var, /tmp partitions with all your old stuff but in all the right places, and the rest of your drive accessible as /data.

Good luck.
OK, on looking back at your df output in THIS thread, it looks like you are mounting stuff as /dev/ad0s1a, not just /dev/ad0s1.  In which case, that's how you should be referring to it in any of the stuff in my above instructions.

Always compare carefully with what you really see in your own mount table.

Again, good luck.

rm -rf /usr/obj/*

okay.. my take is that i should:

1) cd /usr/ports
2) rm -rf */*/work
3) make clean
4)  rm -rf distfiles/*

but right now i am making k3b in /usr/ports/sysutils..

umm.. is that included in */*/work?
it doesn't seem i better make clean in /usr/ports while that's running..

arg.. maybe not even the distfiles one

okay.. a clarification for mr.  jrssystemsnet ..

yer amendment post notes the correct /dev/ad0s1a  thingy dingy..

i didn't really do that, it is some sort of freeBSD standard i don't know exactly why it happened, but
note that when i created the nonbootable swap on the third partition it became known
as /dev/ad0s3c  but that happened not based on me giving it such a designation but following
some directions that never had anything to do with naming the device explicitly (at least
that i observed) with  some comand that contained any strings such as "ad0s3c" or "ad0s1a" or whatever..

so now i am a little tripping about designationing /dev/ad0s5 as is, or perhaps
/dev/ad0s5c or /dev/ad0s5d or /dev/ad0s5a  or whatever..

any thoughts?

today i have designated time to perhaps explore new werlds on my HD, but meanwhile
my k3b dvd burner port make is still cooking....

i am going to keep tri-booting for now (i have uncle bill on partition 4, which is sort of important for now
as i have been able to do a few things like access my SD drive.. umm.. i ferget there might have been a
few things.. but also get a dialup connection at home has been a big one.. )

i needed freeBSD 5.4 to mount the dvd drive.. umm.. i think i have java installed on 6.0, and also mico..
very soon i need to do my distributed project i will be in big big trouble if i can't accomplish that..

i really like my swap on partition 3.. at least as long as i have two freeBSD boots.. heh {:}  i will probably
keep it even if i do move to only one freeBSD boot just to be novel..


i can't think of why i really decided to post this message  {:P
kayveyAuthor Commented:
i just thought of one thing..

ad0s1a is freeBSD 6.0
ad0s2a is freeBSD 5.4

so maybe i should step on ad0s2a and reboot a freeBSD 5.4 there step on it substitute ad0s2a everywhere
where ad0s1a is?

yeah.. that feels right to me.
kayveyAuthor Commented:
i just realized the freeBSD 6.0 installation is the one that needs the memory..

therefore.. i need to use the freeBSD 6.0 disks to do all of this, don't i?

arr..  {:P

you are talking about /dev/ad0s1(a) and freeBSD 5.4 as if they are one and the same.

this is not correct...

/dev/ad0s1a is freeBSD 6.0 and is 80% utilized
/dev/ad0s2a is freeBSD 5.4 and is 32% utilized

i wish this danged make would finish

About cleaning space - either way does, I simply posted quicker way.

I think that what gheist meant by "too many forks" is that doing a "make clean && make distclean" creates many child processes during the cleaning of the various ports and the "&&" adds another fork still...make clean and make distclean "politely" clean up your work dirs and his suggestion of rm'ing the distfiles dir will do almost the same thing in a faster (if less gentle) way. I have a pretty fast machine and don't mind doing a make distclean, but it DOES take time.

making a /data dir with lots of space and then making /usr a link to /data will effectively mean that /usr has a lot of space.
kayveyAuthor Commented:
what freeks me out is if i have a /usr already, then additionally do a command like
ln -s /usr /data (am i transposing? i don't know which path is real and which is
a link)  the thing that freeks me out is what if the directory
/usr actually exists in like the one partition..then i add the partition /data and now
/usr is supposed to point to /data but /usr is real.. a link is like an emphemeral
thing that doesn't really exist except pointing to something real... sort of like a
pointer in c:

int * p
p = malloc(4);

p doesn't exist, but the stuff malloced does..

now it seems to me if you have an actual /usr directory _and_ you want to make /usr
exist as a pointer to something else called /data, yer filesystem is not going to know
what you mean by /usr.. does it mean the real /usr, or does it mean /data

therefore.. i don't see wtf a thing called /data should exist.. the new partition
should just be all of /usr
