I found that /fact is not enough space,
can I "free" /mis and then "give" to /fact?
How ?

You will need to back up the data on /dev/dsk/c0t4d0,

then reformat the disk using format, and restore the data to the freshly pastioned disk.

Using format directly will destroy the data on the disk.

Any other method without backup data?

Depending on your flavor of Unix and the packages you have installed you could try the command "growfs".

To find out more try "man growfs" for the online manual pages or look to your administrator guide.

Typically this command is available on most platform but occasionally (as is the case with Solaris) there must be add on packages installed ...in the case of Solariris it would be the online disk suite or volume manager.

Good Luck !

Just a followup ...I assume you have already went through and manually cleaned up this filesystem right ??

Looking for large "core" files, tmp files, JUNK files ..etc ...

Especially core files ...they can get quite large !

symbolic linking a large /fact directory to /mis may suffice for your purposes

Symbolic likns wouldnt work until the target filesystem was removed ...cant link 2 existing filesystems to eachother ... am I wrong ?? dont think I am ?

jonkeCommented:
I think ozo just means move over a reallly large file into /mis. Delete it from /fact, and create a symbolic link in its place. It's a messy quick fix, butmuch easier and quicker than repartioning the disk.

You can symbolic link from one partition to another without a problem.

jonkeCommented:
Try this:

mv /mis/largefile /fact/largefile
ln -s /fact/largefile /mis/largefile

Looks good !
Logout...just so you understand why you are linking as well as moving the file.
MV will actually place the file or directory into a new filesytem space, however your apps may still be pointing to the old location therefore you need to use the symbolic link to ensure that the move is transparent to your apps.

well done guys, quick simple accurate.

Unmount the mis file system and mount it as a
sub dir of fact file system. then you can use this space as /fact/xyz.
