Would appreciate any thoughts. Have been trawling posts for 2 days and not having any significant luck.
Only started getting partition full erors approx 12 hours after a reboot, has been fine for months prior to that.

Code:
[email protected] [/]# df -h
Filesystem            Size  Used Avail Use% Mounted on
/dev/sda5             9.7G  9.5G   34M 100% /
tmpfs                 1.9G     0  1.9G   0% /dev/shm
/dev/sda1             291M  138M  138M  51% /boot
/dev/sda8             258G   13G  233G   6% /home
/dev/sda7             3.9G   73M  3.6G   2% /tmp
/dev/sda2             9.9G  6.8G  2.6G  73% /usr
/dev/sda3             9.9G  1.3G  8.2G  14% /var
xxx.xxx.xxx.xxx:/mnt/tank/skunkworks/tank.xxx.com
                      200G   23G  178G  12% /mnt/backups
backup is on / but it's linked to /home/backup but it's empty/not in use
I also have remote /mnt/backup and this is where backups are directed

nothing at all dramatic when doing a ls in /root

fstab looks like this

also if I'm in / and do a

Code:
ls -lR | less
and then scroll through everything, nothing at all jumps out at me as an especially big file.

have done a
Code:
yum clean all
no mention of disk errors in /var/log/messages at all

lost+found is empty

I've been through pretty much everything and removed what I could.
I'm think I'm now getting snow blind

hoping someone here can make further suggestions?
I haven't tried a reboot yet, thinking that's next.

you can start with this:
Code:
du -h --max-depth=1 /
then you will see what directory is taking the most space.
Just ignore those that are mounted, i.e. /home /tmp /usr /var

thanks for the help!

running du -h --max-depth=1 / now it got down to /tmp and then looks like it's either still working or died, will let it run and report back.

I also don't have a /home/cpbackuptmp/ dir at all anywhere on the machine.

well du -h --max-depth=1 / has been running for about 9 hours now and just seems to have stopped..
output is currently as below
any further thoughts greatly appreciated
the 15-20 meg of space I cleared up last night by removing a bunch of small stuff seems to have been filled again now

I tried unmounting the nfs mount /mnt/backups in case that had anything to do with it.
no change

I also just rebooted.
no change.


any further thoughts greatly appreciated.
