To find the 10 largest files, use:

find / -xdev -exec ls -la {} \; sort +4 -nrb | head -10

From the / filesystem

du . -xdev -ka | sort -nr more

This will list filesin the root FS in ascending order by size and will not cross filesystems.

find / -xdev -size +1000000c

That will give you files greater than 1 meg.

Be careful what you delete.

If it's a process that's killing you, you can use the following to see what processes are generating a lot of CPU (and therefore maybe a lot of disk in root):

ps -ef | cut -c42-80| sort -nr | head

Hi:

In addition to the techniques already presented, look for ordinary files in '/dev/' -- files whose mode in an 'ls' listing begin with "-" instead of 'c' or 'b'.

A common mistake is to mistype a backup device filename. Instead of '/dev/rmt/0m' you type '/dev/rmt/om' and create an ordinary file of vast size.

Hy priyarajan,

1.- run attach script

2.- View file /tmp/root.txt and create directorys for applications, etc.

hi priyarajan,

did you check for any "core" files in /

e.g.

# ll core
-rw------- 1 root root 484972 Feb 8 11:08 core
# file core
core: core file from 'bootpd' - received SIGSEGV
# rm core

a) Trim your application and system log files located in /var/ directory
b) Cleanup unneeded patches as cleanup -c2
c) Find core files and delete them.
d) Chances to have source or depots files in .tar.gz or .tar file format. If you don't want to have them move to some other machine or delete it.

Hi,

Use
find / -xdev -size + -exec ll {}\;

will list all files > size mentioned.

check /etc/lvmconf/*.conf.old and delete them.

thanks

Hi
You may use
find / -xdev -size + -exec ll {}\;
will list all files > size mentioned.

Other things cud be

1. check /dev directory, especially if you just tried some backup
2. look for core* files in the / filesystem.
3. Ensure that all the filesystems on the system are mounted. e.g., if u have a filesystem /xyz and it is not mounted, the users/processes can still write to this filesystem eatinginto the / space.
4. check /etc/lvmconf/*.conf.old and delete them.
5. You can also trim the /var/adm/syslog/syslog.log and any other logfile in this path
