/root drained up all the disk space

ben randall · 07-08-2009, 11:04 PM

hi all..
i'm manages 4 CentOS server farms which serves around 2000 clients.
All the servers in a good condition except for the server no.4.
the server's hard disk is drained up pretty fast,even after clearing cache,disk usage is still around 90%.
After investigating where all the space gone,i found that /root directory consumes 86Gb,which is 87% of total disk space..But i haven't found any suspicious files inside /root..
please help..
any ideas is highly appreciates..Thank you in advanced.

I'm a little confused. You are saying that 87% of /root disk space is filled up but are are not sure what is causing it?

Have you done a "du -h /roor/" to see how big those files actually are? Sounds like to me you have some more cleaning to do.

thanks Biggen.."du -h /root/" produce a very long output..mostly comes from /root/.trash.
how to permanently clear all the files?

Empty the trash ???
You should first note what's in there, & fix the problem, otherwise you'll be doing this again ... and again ...

How the heck do you get so much in /root? Or your client?

I have always associated .trash with a GUI, but that might have changed. So the question would be why there is a GUI on a server?

all those files are originates from SARG..it keep storing data but didn't reuse the directory..so,i remove the files.that was the problems.so,i get rid of SARG,since it doesn't important to the system anymore.

You could try

to purge all the files from the trash

Code:

rm -rf --preserve-root /root/.trash/*

and then, to prevent anything from putting anything in your trash ever again, make the .trash directory immutable (unwritable)

Code:

chattr +i /root/.trash

chattr +i /root/.ssh

Right idea, but wrong directory.

That will prevent him from ever saving new host keys again.

Yes you are right, I meant to write .Trash, of course, occupational hazard I guess because I find myself making .ssh folders immutable quite often.
