filesystem problem

[Midrange]

Hi there, i have two problems on my server.

1. the / filesystem always reach 100%. I have checked the files under 100 there is no major changes like the smit.log, etc..the only files that is increasing is the file on the /etc/lpp/diagnostics/diagrpt* but with minimal size.

my question is , our filesystem like /oracle which is mounted on another disk should not affect the size of the /fileystem ? Even though if i used ls -l under the / it will show to me that directory name.


2. I always received a mail with power supply problem but when i run diag there is no hw error. No error log report also on the errpt command. How can i get rid of that mail since i checked it already thru diag?

thanks.

1. Check files that are being modified daily:

find / -type f -xdev -mtime -1 -print | xargs du -ka | sort -rn

Run that a few days in a row (save the output, but not in / though and compare the results.

If /oracle is a separate filesystem, it will not affect the utilization of /

2. check cron. The system can add a cron entry to send a message.

thanks Glenn, we have done that. We managed to see the files but those files are not increasing with a big amount compare to the / filesystems.

Have you checked hidden files?

Also take a look in /dev , There shouldn't be any large regular files present.

find /dev -type -f -size+1000 -ls

If you find any, post the output of the find cmd here.

Hi,

Be sure all your other filesystem are mounted.
Sometime a filesystem on (say /mnt/yourfilesystem) is not mounted for some reason and the files writen by the application to this filesystem goes to /mnt/yourfilesystem directory witch belongs to / filesystem

p5wizard, yes i have check hidden files but no files have a huge amount and there is no output on the cmd you gave under the /dev directory.

aau, all filesystem are mounted ..

tnx

Well then perhaps you just need a bigger / filesystem...

What is its size now?


Another thought: have you deleted a large file some time ago? Perhaps that file was still in use and it is not really deleted, just invisible to you (and to ls, find, ...)

See if the free space reappears after a reboot.

Check /var. Sometimes log files grow liek Topsy (the problem being to find out why). Spool files can also get their underwear in a twist. I take it no core files are appearing?
