du locked up and crashed hardrive FreeBSD 7.0

I have an ASUS laptop

http://www.monkeyview.net/id/965/fsck/dmesg/PB12001901.vhtml

with three hardrives in various state of software and hardware distress, but I get by. Right now, I am
running

# uname -a
FreeBSD kayve-PC 6.2-RELEASE FreeBSD 6.2-RELEASE #0: Fri Jan 12 11:05:30 UTC 2007 root@dessler.cse.buffalo.edu:/usr/obj/usr/src/sys/SMP i386
# killall moused
# moused -p /dev/ums0

on a hardrive that makes scary sounds when it over heats.

my shell happens to be pointing to

# pwd
/mnt/usr/home/kayve/cs162

which is one of the four partitions (that was actually a boo boo.. I should have made only one partitiion)
of a newer hardrive that is the subject of this question. I have mounted it on /mnt/usr

I was in a frantic session of svn-ing and java-ing and decided to do a du command. it scrolled and scrolled
and then suddenly everything froze. after that, I haven't been really able to boot that hard drive. I did
a vipw and got my user back, and the way it was booting I would get a character based prompt (no
X) but then after logging in and getting my prompt I would type "startx" and I would get KDE. after
rebooting multiple times it seems I can usually get a prompt (although it rebooted between
the username and password once) .

Here is the interesting output of fsck_ffs -y.. I did this instead of just fsck because fsck "couldn't find
the filesystem type" and I did the -y "constitutive yes" because of what you see...

# moused -p /dev/ums0
# fsck_ffs -y /mnt/usr
** /dev/da0s4 (NO WRITE)
** Last Mounted on /mnt/usr
** Phase 1 - Check Blocks and Sizes
INCORRECT BLOCK COUNT I=2779162 (4 should be 0)
CORRECT? no

An interesting thing about the whole du thing is that it seems like it fails in the exact same directory, and
I have done the du command while booting THIS harddrive and it deadlocks in a very similar way but this
disk is still able to reboot after that.

I have yet to try the obvious deletion of the nasty directory.. I'll probably get around to doing that when I
have timeto make a backup. {:}

If that's the solution.. EASY POINTS for someone!

Kayvey, don't tell me you STILL have that 'about to breakdown months ago' HD in your laptop?

Sounds like an unhealthy hard drive, indeed.... You may want to get your important stuff off of it and get a new one.

ASKER

Here is another snippet, waiting for it to finish:

# mount /dev/da0s4 /mnt/usr
# fsck_ufs -y /mnt/usr
** /dev/da0s4 (NO WRITE)
** Last Mounted on /mnt/usr
** Phase 1 - Check Blocks and Sizes
INCORRECT BLOCK COUNT I=2779162 (4 should be 0)
CORRECT? no

fsck_ufs: cannot alloc 871186332 bytes for inoinfo
#

I am wondering if this error could be related to something in my laptop other than the hard drive. also,
the du fails on that same directory. when I get home I could take a picture of that. the fact that
it is looking for 0.87TBytes reminds me of something that was happening on a THIRD hard drive..
I have some pictures of that online...

ASKER

this is the hard drive I am running now. It is my oldest of the three..

http://www.monkeyview.net/id/965/fsck/inst_world/p5240182.vhtml

it has a broken vista partion and

this is my second hard drive:

http://www.monkeyview.net/id/965/fsck/newhd/PC010317.vhtml

that's the one that is running vista. it has a broken FreeBSD on the other partition

I don't know if I have a picture of the newest hard drive, it has 160GB, all devoted to FreeBSD 7.0..
let me search a bit more....

ASKER

here is the newest hard drive, the one that had this du error of which I speak

http://www.monkeyview.net/id/965/fsck/torrent/p5120227.vhtml

here I am swapping

TeRReF:
The "about to breakdown months ago hardrive" I never threw out! right now it runs my only good
freeBSD! I feel like I have correlated it's clunking sounds well with time of use. It gets hot, and starts
clunking. Last night I forgot to hold down the power button and it stayed on in my backpack all the
way home accross the Bay on BART (I guess that takes a total of around an hour to walk down
the hill thru the Berzerkeley campus.. wait for a train. 26 minutes to Civic Center SF, I don't know another
20 minutes on the Haight Street buses.. I got home and it still had that freek weird pixelated gnome shutdown
screen..

http://www.monkeyview.net/id/965/fsck/ubcd/pb220076.vhtml

right now, I am in the SFSU puter lab, with the new 160GB drive with the du error mounted on
/mnt/usr.. I just updated /etc/fstab so maybe I can boot up with it plugged in?
# cat /etc/fstab
# Device Mountpoint FStype Options Dump Pass#
/dev/ad0s2b none swap sw 0 0
/dev/ad0s2a / ufs rw 1 1
/dev/ad0s2e /tmp ufs rw 2 2

/dev/ad0s2f /usr ufs rw 2 2
/dev/ad0s2d /var ufs rw 2 2
/dev/acd0 /cdrom cd9660 ro,noauto 0 0
#

right now I am using my NexStar-3 hard drive enclosure to USB mount (/mnt/usr) the 160GB drive
and I can access my files (and run fsck just fine)

some advice about fixing and/or diagnosing this bad hard drive was given on this question:

https://www.experts-exchange.com/questions/23798042/can't-svn-commit-to-https-repository.html

ASKER

jeeee hoo see fat!

I just had to reboot multiple times.. I finally took the /etc/fstab entry out.. I HOPE that I don't crash
again..

I just wanted to say.. umm. you DO realize I sorta messed up on that hard drive in terms of I
accidently made 4 partitions instead of 4 slices so I have a different partition for swap, / /usr and
what, /var? when it boots it asks me what to boot on, F1-F4 all Freebsd..

anyway..

::phew:: gotta go!

ASKER

I think one of these files is the culprit

I think I did that. I came up with a new idea.

you can't see it on this link:

http://www.monkeyview.net/id/965/fsck/torrent/p5120215.vhtml

but the new hard drive is marked "600mA" while an older one I have is
marked "1A"

Did I fry my new hard drive with too many amps? {:(

Okay, you are saying that fsck should work, but I have done it multiple times and it always says this:

fsck_ufs: cannot alloc 871186332 bytes for inoinfo

I tried deleting the directory du froze on, and it just froze on another directory. My FEELING
is that I DID do an fsck on it unmounted at least once, but I will try at least one more time.

My idea is that the amperage incompatibility caused me to ruin my hard drive, but you are
saying that doesn't make sense. When I bought the second hard drive (120GB), the guy
at central computers was all insecure about advising me since I was using FreeBSD I was
supposed to know. The whole experience for me was unpleasant enough I decided I
would rather keep my mouth shut, so the next time when I bought the newest (160GB)
hard drive, the one that needs the fsck for this question, I didn't bother asking anybody,
I just went in there and pointed, "I'll have THAT one," and they sold it to me say no more.

I should have RTFM the library of congress that is computers, I guess.

"My idea is that the amperage incompatibility caused me to ruin my hard drive, but you are

Right! This doesn't make sense; you can't push Amperes into something that doesn't want it unless you use a too high voltage, which is nonsensical in this situation. Computers have pretty good power management generally.

You may have to realise that you're dealing with HDs that are on the edge and not totally reliable. Why waste your time on this? Copy important data off those thingies, get new drives as necessary and get on with a normal computer usage.
/RID

ASKER

I am not rich like you. I will not buy any more hard drives from central computers.

ASKER

The old clanky hard drive is in the machine now. You are insulting my hardware I bought for $89. Great.
Is this because I was clinging to IDE technology (that's all I have for now).

Sugar momma promises to buy me a new puter for XMas. Do you have recommendations for better
hardware? I want to keep doing this hard drive swap thing. She doesn't want to mess with the
No OS nonsense we did this time. I guess I will get something running vista because I don't think
I want impaired performance with wine running ChessBase. The number of chess positions is
estimated at 10^120. ChessBase might be the reason this hard drive is clunky. I was running
it all night to try to assess a chess position when it started making noises. I don't feel like messing
with the dual boot crap any more. I like carrying around my handy screwdriver. Umm.. long story
short I want to get an extra hard drive and now they have been giving us openSolaris. I feel like
taking a crack at that. I'll be putting that in an additional hard drive the sugar momma is buying.
Also, do they have laptops that have swappable motherboards nowadays? That would be cool.

ASKER

btw, I accidently put the FreeBSD 7.0 160GB IDE hard drive we are diagnosing into the boot position just
before. It allowed me to log me into the character based part (you know, like with the beastie). Startled by
my mistake, I paused, then went ahead and typed "startx." I thought it was going to go up for a while,
but then it rebooted. I hit "4" and went into single user mode. Typed "fsck."

looked exactly like the output of the below "fsck_ufs" command:

# killall moused
m# # moused -p /dev/ums0
# fsck /dev/da0s4
fsck: Could not determine filesystem type
# fsck_ufs /dev/da0s4
** /dev/da0s4
** Last Mounted on /usr
** Phase 1 - Check Blocks and Sizes
INCORRECT BLOCK COUNT I=2779162 (8 should be 0)
CORRECT? [yn] y

fsck_ufs: cannot alloc 871186332 bytes for inoinfo

err.. correction.. I think it checked /dev/da0s1 first and it was fine.

Putting a computer in the freezer?? If you do that the condensation will ruin it for sure!

I wasn't going to leave it in for long.. umm.. heh {:}

well.. I pulled the nexStar out of the puter getting up to go to the fridge. Maybe I
would have put it in the fridge. Big computer facilities have really power AC units,
I know..

/usr/src/tools/tools/recoverdisk was running a reaall long time. Could you make out
the output data? The tabular format got a little messed up by my cut and paste operation.
Do those numbers look right for a 160GB HD? Here, let me fix it for you:

# ./recoverdisk /dev/da0s4

Also this didn't exist:

/usr/ports/sysutils/ffs2recov

I was figuring I would try again, but right now I am running the intermediary (120GB) HD..
let me reacquaint you with my disks:

relative age capacity dual boot? partition 1 partition 2 notes
oldest 60GB yes FreeBSD 6.2 Vista makes the

umm.. I made a boo boo I guess. the FreeBSD 7.0 KDE HD is not _really_ operational, of course..
I HAVE been getting a shell but X won't start.

My old friend kayve!

In your initial post you did irrepairable damage by mounting file systems and fscking it while mounted.
It is up to you to decide if you reinstall or restore from backup. There are no other options.
Do not get mad at me - it is now your fault, not coincidence.

ASKER

I don't believe you. You have been wrongly accusing me of using less than perfect English. I don't understand why you hate me, but you obviously hate me. My professor said I might be able to fix it.

ASKER

Okay maybe you are not lying.

http://en.wikipedia.org/wiki/Fsck

However, I believe you have the skills to fix "severe data corruption/loss," but for unknown reasons
you hate me, just like many other computer scientists aaaalllllll hate each other.

2442045 records of 6536 bytes each iso only 149GB. Is that a problem?

Drives are sold using decimal terabytes.
it is 160GB in marketing catalog
that yields 149 binary GB

Problems are at 128GB, 32GB,8GB,2GB,1TB (binary xB)

ASKER

I have to get out my screwdriver and put the 160GB hard disk in the computer instead of in
the nexSTAR?

http://www.monkeyview.net/id/965/fsck/torrent/p5120226.vhtml

Make sure you have only target disk and install cdrom when installing. otherwise you may lose more data than you wish.

ASKER

I should burn this disk:

ftp://ftp.freebsd.org/pub/FreeBSD/releases/i386/ISO-IMAGES/7.0/7.0-RELEASE-i386-livefs.iso

or this one?

ftp://ftp.freebsd.org/pub/FreeBSD/releases/i386/ISO-IMAGES/7.0/7.0-RELEASE-i386-bootonly.iso

ASKER

I can boot to single user mode with no disk. I have not run fsck -f (although I did use -y). I need
cd "target?" to fix hard disk is what you are saying?

ASKER

When you say "target disk" you mean the abused 160GB hard drive I guess?

ASKER

So "only target disk" means I get out my screwdriver and swap the "clunker" 60GB FreeBSD 6.2 that I
am currently running out of the master slot

http://www.monkeyview.net/id/965/fsck/torrent/p5120212.vhtml

and put the 160GB FreeBSD 7.0 abused by fsck disk into that slot. I need "install cd" which I think
is one of two options above. I boot up on cd instead of hardrive 160GB FreeBSD 7.0 and do the
fsck's as directed? Or boot up on 160GB FreeBSD abused by fsck and then put the cd in or using
my MBR direct booting to master hard drive?

CD1 is smallest that does without network connection.

ASKER

So I want bootonly, and I should screwdriver in the "target disk" into the master slot?

Maybe I shouldn't be using the term "master" because I do not fully understand it. The thing I felt like
clarifying is that in this picture:

http://www.monkeyview.net/id/965/fsck/torrent/p5120212.vhtml

you seem me unscrewing the bottom of my laptop where the hard drive goes. Right now,
the disk that is screwed in there is the 60GB running FreeBSD 6.2 disk that is "clunky" but
not "abused by fsck."

My understanding is that I should unscrew this and take the disk out of the "nexStar"

http://www.monkeyview.net/id/965/fsck/torrent/p5120226.vhtml

which IS the 160GB disk running FreeBSD 7.0 that is abused by fsck and screw that into
the actual laptop frame which is depicted in the first URL on this post.

When a disk is screwed into "nexStar" it appears as /dev/da0
When a disk is screwed into the laptop frame, it appears as /dev/ad0

Just a review of what I posted before:

# cat /etc/fstab
# Device Mountpoint FStype Options Dump Pass#
/dev/ad0s2b none swap sw 0 0
/dev/ad0s2a / ufs rw 1 1
/dev/ad0s2e /tmp ufs rw 2 2
/dev/da0s4 /mnt/usr ufs rw 2 2 <<----took out this line
/dev/ad0s2f /usr ufs rw 2 2
/dev/ad0s2d /var ufs rw 2 2
/dev/acd0 /cdrom cd9660 ro,noauto 0 0

You see the /etc/fstab that I actually have edited I think. I think I had to take out the line
with the /dev/da0s4 which is currently the 160GB FreeBSD 7.0 disk that is abused by
fsck, but by using my screwdriver, I can make that disk appear in my /dev ls as ad0 instead.
That is what I am assuming I should do.

What are you talking about?

ASKER

I "abused" my 160GB hard drive. I am running a _DIFFERENT_ hard drive. I used a purple USB linked
hard drive enclosure called a nexSTAR to run a bus from one hard drive to the other. I am operating
under the assumption that I am to reinstall the fsck abused 160GB hard drive into my laptop case

(have you looked at the two pictures in the URLs I gave you above? that would be simplest)

and then I can boot on the 160GB hard drive running FreeBSD 7.0 that needs an fsck instead
of running the 60GB hard drive running FreeBSD 6.2 that is in the laptop case now. I guess you
said it didn't matter what I boot, so perhaps I could do either. I just don't want to make any mistakes
and abuse my hardware more. Single user mode was mentioned, and the only way I know how
to do single user mode is to get my screwdriver out and put the right hard drive in the laptop...although
I guess I could envision mounting a /dev/da0s4, er.. I mean NOT mounting it but following the
instructions you gave very carefully that is listed above.

thanks for the clarifcation! ACK! {:) I should have realized...

I felt like commenting on this. I am taking a few courses at UC-Berkeley lately, and
this summer they told us a better system of doing this stuff:

Kilo = 1000 KiBI = 1024
Mega =1000 000 MeBI = 1024 * 1024
(etc all the way up to "yobi")
People should adopt this system! {:) It would avoid these problems!

Okay. I just realized I made a typo:

you seem me unscrewing the bottom of my laptop

seem = see

Sorry about that.

ASKER

When you told me to mount my hard drive with a screwdriver, I thought this is what you meant!

ASKER

okay. the procedure has been followed. Newest hard drive screwed into laptop. Bootonly disk provided
confusing irritations with sysinstall. Tried fixit mode in sysinstall. Was I supposed to let it install?

# fsck -f -y /usr
** /dev/da0s4 (NO WRITE)
** Last Mounted on /mnt/usr
** Phase 1 - Check Blocks and Sizes
INCORRECT BLOCK COUNT I=2779162 (4 should be 0)
CORRECT? no

fsck_ufs: cannot alloc 871186332 bytes for inoinfo
#

This is what it looked like. It takes maybe 20 seconds to run. I type the command fsck -f -y /usr
and that exact thing happened again. It didn't run for 1h15m it gave me my prompt back. All
other filesystems (/, and /var) were okay. I didn't do the swap partition. Btw.. I accidently
configured this hard drive to have 4 partitions instead of 4 slices so MBR comes up and says

FreeBSD press f1
FreeBSD press f2
FreeBSD press f3
FreeBSD press f4

Also, I didn't allocate one area of disk to any partitions, approximately 10% thinking that would
help things. All this configuration happened many months ago before I managed to install
KDE and run anything. I am just clarifying the configuration.

ASKER

The guy downstairs said I need to kernel debug core. I found this page:

http://www.freebsd.org/doc/en/books/developers-handbook/kerneldebug-gdb.html

He mounted my /var partition from the USB nexstar and found the crash directory. I mounted
my /usr partition on /mnt/nexstar and found that path they were talking about in the handbook..
so I managed to make the kdgb work.

"swapon" gave USAGE: error, but "swapon -a" seemed to know what it was doing...

but the fsck -y -f /usr did the exact same thing.. maybe It thought for a solid minute or
two instead of 20 seconds. Maybe that was because I was staring at it.

# top | grep dd

Should it be on top? Will it ever end?

ASKER

You can't tell from the above command line dump, but "top | grep dd" returned absolutely nothing.

Your filesystem is so tricky broken I'd suggest you fill bug report at FreeBSD to fix it, and for your computing experience install fresh OS on that computer.

It is actually a customized kernel, it may crash because of you. Why not GENERIC kernel?

You might be able to fix filesystem using OpenBSD or NetSBD CD-s. But otherwise reinstall.

ASKER

I think KV_KERN is because of acd0 only. It should be mostly the same as GENERIC

do my extra options mess things up?

I guess I don't want to use this?

You should not place the output directory on the same block
device you are trying to rescue files from. This might add the
same file to the block device ahead of the current reading posi-
tion, causing magicrescue to find the same file again later. In
the worst theoretical case, this could cause a loop where the
same file is extracted thousands of times until disk space is
exhausted. You are also likely to overwrite the deleted files
you were looking for in the first place.

-r recipe
Mandatory. Recipe name, file, or directory. Specify this as
either a plain name (e.g. "jpeg-jfif") or a path (e.g.
recipes/jpeg-jfif). If it doesn't find such a file in the cur-
rent directory, it will look in ./recipes and PREFIX/share/magi-
crescue/recipes, where PREFIX is the path you installed to, e.g.
/usr/local.

If recipe is a directory, all files in that directory will be
treated as recipes.

Browse the PREFIX/share/magicrescue/recipes directory to see

I'm not trying to rescue. I'm not sure what that was suggested on

Okay I give up examining the inode. I am just going to do the stuff in single user mode fsdb:

http://phaq.phunsites.net/2007/07/01/ufs_dirbad-panic-with-mangled-entries-in-ufs/

If you do not need files on broken system then just reinstall with something useful. Otherwise boot off installation CD of either OpenBSD or NetBSD and run their fsck.

dd will not fix anything at least the way you use it.

Are you trying to look stupid or you just are like that?

I can't dump my data unless I get another hard drive. Why is it stupid to try to learn better techniques??

I know now I need to learn better mirroring techniques. I know I could just reinstall. I want to reinstall but I guess my "problem" is that I am a pack rat. Right now the guy downstairs showed me a cool thing with kgbd and now I have discoved I can do what I wanted to with fsdb.

Is it safe to run fsdb not in single user mode?

I know I could burn dvds but I don't want to make that mess. Maybe I will try to get my stuff on hard disk
2 and reinstall that first.

I do not look into your pictures - they are on slow server and overly huge. Use ee-stuff to post them.

It is obvious bug in that fsck you are using it allocates 800MB of RAM. I beg you try OpenBSD's or NetBSD's fsck to see if bug is generic or specific.

OpenBSD has ffs recovery tool designed for you that lets you bring up even after overwriting beginning of disk.

1) since you were able to read whole disk odds are high you will install Linux till the state you are able to use smartctl or smartd to judge disk health.
2) for sake of bug reporting use G4U to transfer sick partition for safekeeping and bug reporting to some ftp server that has reasonable space
3) I am not in rat packing business - do you eat them over there in US?

ASKER

I don't know why you keep insiting on insulting me. I was using dd to see what was
in the inode to decide if I could just delete it or not.

ASKER

insiting = insisting

fsck -y includes saving inodes under lost+found, so you can examine their content after fsck. It is fsck bug it crashes allocating enormous amount of ram. so I suggest ignoring insults and getting OpenBSD, NetBSD, FreeBSD 6.3 or RatBSD if you choose so that you can check filesystem with working fsck.

It is actually more useful if you image your current failing disk and examine it later.

For reference: fsck counts blocks from beginning of filesystem aka BSD partition aka Disklabel partition like da5s3i

Are you able to burn ISO images into CD-RW so that you can diagnose your laptop without extra finance?

fsck -n prefers data-losing way.

I did a clri 975064 in fsdb (not shown, but on monkeyview)
quit fsdb and fsck_ufs -y -f still didn't work (looked same as other runs)
went back into fsdb

fsck has always talked about INCORRECT BLOCK COUNT I=2779162
so I thought it would be good to go to that inode.

GEN=ffffffff.. very large unsigned or negative signed number. Doesn't seem right, does it?

I guess I didn't take pictures but inode 2779161 was okay and 2779163 and 2779164 also
had strange GEN.

This is going to be moot I guess. Maybe I should just give you points for the not really helping advice of blowing everything away, or maybe that was good advice.

You gave enough advice to certainly deserve points.

It seemed they were just giving a 'boot from CD' situation. I don't like all those awful sounds coming from my CD drive! I decided to just put a FreeBSD 7.0 on that free Partion. It felt easier like something I knew better. Sorry about that. Maybe I will try the boot from CD to fsck at some point. For now, maybe I am happy to have a
nonbootable but mountable hard drive for future backups.

Download Mandriva One or Kubuntu - they boot from CD to make use of your Clunked OMPUTER (tm). Owing to technological differences they boot and install without that much CD head movements.
