/ filessystem FULL

[Henry Chua]

My /root filesystem seems to be full, but is there anything I can do to free some of its spaces. there seems to be very little files I can clear to free spaces....

Thank you all for your kind advises..

There are a few places you can look.

core files (find / -xdev -name core -print)
du /dev (could have a bad /dev/rmt file)
du /etc (excessive logging in EMS- /etc/opt/resmon/persistance)

Hi Henry,

the command that can come in handy would be

#du -kx / |sort -n

It will list all the directories sorted by their sizes with the bigger ones at the end. Look in those directory. Often application directories created with non-root owners can fill up / filesystem inadvertantly. Sometimes special files like /dev/null, /dev/rmt/0m, /dev/vgxx/* files will become regular files thus filling up /. Above 'du -kx' should show them.

There is a nasty little way space can be occupied but invisible.

lets say we got a folder called /var
There is usually a filesystem mounted there.

Lets say we figure out how to umount it or it fails to mount at boot.

Then 100 MB of data get copied in.

We realize the system is screwed and reboot. This time it mounts.

Is that 100 MB sitting in the unmounted /var folder visible? No. Is it taking up space? Yes.

When all else fails, you may need to take the system into single user mode when no filesystems are mounted and look around.

To do that, boot, intervene at the 10 second prompt(at console)

hpux -is

Single user mode.

Check out those folders.

Have a look at /var and /etc directory.
Check for /tmp too

Use #du -kx /|sort -n
and checkout which directory covers more space.checkout that directory using
#du -kx |sort -n

cleanup some space this way.
U can even move some lager files to some other filesystem and and create symbolic link to it.This should be done if the file cannot be deleted.

I agree with the suggestions about using du -k piped to sort, but I always use the option sort -nr so that the largest entries are at the top - I find this more useful.

hi,

check on the root file system with the following command to find large files.

find / -size +1000000c -exec ll {} \;

or

find / -xdev -size +1000000c -exec ll {} \;

one common error is that when doing tar backup if you are giving backup device incorrect ,it will create a tar file in /dev/rmt.check for that.

regds,

While in a directory with a lot of entries, this will give a list of the largest files. Often they can be trimmed, moved, or deleted.

ll $1 | sort -n -r -k 5,5 | more

[twang]

to find recenty created large files:
# find $DIR_TO_SEARCH -type f -size +$FILE_SIZE -mtime -$DAYS_SINCE_CREATED -exec ls -ls {} \; | sort -n -r | tee output.log
