file system full

[Mazen Al-Jarrah]

hi everyone,

my root file system / is getting full what files should I delete to reduce it...?

thanks

[Steven E. Protter]

cd /
du -k | sort -rn | more

This will list files largest to smallest.

You've got a big one most probably and you need to delete it.

In practice no files should be stored on / only mountpoints to other filesystems.

Hi
Do this (delete core file):
#find / -name "core" -exec rm {} \;
and (listing of the largest directories first):
#du / | sort -r -n | grep ^....[0-9]
or (list any files in / (or files in directories below /) that have been accessed in less than 4 days)
#find / -atime -4 -exec ll {} \;

Regards

Hi:

Start by looking for non-special (regular) files in the /dev directory. A common mistake is to mistype 'om' instead of '0m' leaving a backup image as a regular file named '/dev/rmt/om'.

Regards!

thanks for your prompt input,
but after sorting out the list, it is showing me that the biggest directory is the current one which is root /

what is next...?

You can do this

#cleanup -c 1

will delete patches that have been superseded at least once (directory /var/adm/sw, /var file system)

Post the bdf result

[Mazen Al-Jarrah]

I found a big file under /dev/rmt
created with a typing mistake that was causing the file system to be full.

Hi,

I would recommend you to move put the /var out of the root vg and mount it in another dedicated VG. Mostly people follow this. What is the size of the root VG. If it has sufficient free space, u can increase the size of /var filesystem.

Post o/p of these commands

#vgdisplay vg00
#bdf
#ioscan -fnC disk
#vgdisplay

You can even have automised script which takes care of log purging in a regular interval.

Check for any core files in the root directory. # file `find / -name "core"` and delete those you dont need. Also you can uninstall unwanted softwares from your server using,

# swlist <>
# swremove
