Reclaiming space on / volume

[Terry Barkoulas]

In trying to solve another problem I noticed that I have run out of disk space on the / volume on one of our servers. I am relatively new to Unix so this may something of an inane question, but can someone tell me if is safe to delete/move the core file that is at the root of the file system since it is taking up to 3MB on the / volume. Also is there a way to "tell" the system to dump core files to another volume

Yes, you can delete/move it - you might want to see what caused it:

file /core

coredumps occur in the current directory that a process was running.

I don't think you can direct them elsewhere...

If space is tight, you may want to make_tape_recovery, then reboot, boot the tape, and resize your root disk.

Hi Terry,

Here's a command to tell you what the largest files/dirs are in a filesystem.

du -akx / | sort -nr | more

largest will be at the top.

Rgds,
Jeff

Thanks for the command Jeff. I found the output interesting to say the least. I am somewhat perplexed by it though since it seems that listing also includes files from another file system on another server. Is it possible to mount other file systems especially from other servers and make them part of the root filesystem.

Sorry about that guys, it seems a file from a restore that went awry caused that entry. Nonetheless thank you guys for your help.
