root file system usage

[Camel_1]

Hi there,

bdf shown / usage us 200MB however du only shown 100MB.

=>du -ksx /
101392 /
=>bdf /
Filesystem kbytes used avail %used Mounted on
/dev/vg00/lvol3 256000 205941 49984 80% /

Is there anyway I can figure which process are occupying the space?

Thanks

you can download and use lsof which will list all open files on / but you will come up with a huge list of processes, the easy way out is to reboot the hard way is to list all open files on / or you can list them all with fuser -cu that will list all proceses on / (still same logic apply, a huge list).

thanks guys.

lsof / and fuser return a huge list, it is hard to locate the problem.

And lsof -aL1 / return nothing.

Any other contribution please.

>>>And lsof -aL1 / return nothing. Any other contribution please.<<<

The command for locating that process is...

# lsof +aL1 /

...NOTE it's a plus "+" not minus "-" for the token specifier.

cheers!

Did you have a filesystem previously unmounted, which sits under /? If the filesystem was unmounted, and stuuf was written there, then you mount said filesystem, you will have used space in /, but will not be able to see it at all.

Hope it helps
