root directory

Rob O'Connor — Mon, 05 May 2003 15:06:30 GMT

Hey everyone:
Well, my weekly seeking help from you guys. The root directory on my system is getting filled. I can't find what's is causing the problem or the files that needs to be clean. The directory that suspected is /etc. The '/' contains the following:
dev
bin
sbin
Mail
dead.letter
etc
.elm
.kshrc
. etc...
I was wondering if anyone has any suggestions on which files to clean. The '\' has 260mb of which close 250mb is used. Driving me nuts! Thanks.

Henry

Hi Henry,

# cd /
# find . -type file -size +1000 -exec ls -l {} \;

will locate your big file in /

Hope it helps,

Robert-jan.

hi,
Try to sue large files using find.
#find / -size 10000 -print

You can change the value 10000 to any value you want.
Another trick is to look at /dev/rmt. Sometimes big files are created when someone type a wrong tape address to do a backup.

best regards.

Hi Henry:

Look for a non-special file in '/dev'. A backup that mis-keyed '/dev/rmt/om' instead of '/dev/rmt/0m' is a common mistake and lead to a very inflated root directory.

Regards!

Run a "du -sk /*" to see where you need to concentrate your efforts. If it is in /etc, then drill down with "du -sk /etc/*" and keep drilling down into subdirectories until you find the offendor.

I would suggest looking for recent files. Do ing a

find / -xdev -mtime 0 -print

will list file sthat have changed in the last 24 hours.

find / -xdev -mtime 0 -exec ls -ld {} \;

will give you a ls -l style listing of each files. It's an easy way to find any non-device files in /dev, as well (look for files with size > 0).

Thanks everyone. Special thanks to Mr. Goossens for the find command. Turns out oracle had mounted a directory on root. Whew!

Hi Henry,

glad I could help, there is little alarm bell in my head at this moment "oracle had mounted a filesystem in root" same id as root or are you using sudo for mounting cdrom's.

Yes it is. I am very concern with that. I just came on last month and still not familiar with the system. As soon as the files on root is cleared, the files will be linked back to oracle directories.
