/dev/root file system full

[Juquin_3]

Hi ,

#dmesg => vxfs : mesg 001 /dev/root file system full (1 block extent)
but #bdf /dev/root = 90 %.
There is not a core file in / , /etc/fstab and /etc/mnntab is good.
Is the File system / corrupted ? How can i resolve this problem?
Thanks

Hi,

search for large files in the root filesystem:

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

good luck,
Thierry.

Hi,

Check /dev directory for some big file.
specially /dev/rmt

Hi,
dmesg shows that at a certain time since last reboot, your root file system was full. The message does not go away from dmesg when the problem is solved, which it apparently has been, as your dbf reports 90%.
If you boot the message will go away and the dmesg buffer will start collecting new messages. So there is probably no problem right now.

regards,
John K.

I will try,

mv /etc/mnttab /etc/mnttab.old.`date +%m%d%y`

mount -a
bdf

Hi Juquin,

If you still have a problem following reboot it may be worth trying the following command (after first cding into the affected directory):

du -k|sort -k1,1nr|pg

This will show you which sub-directories are taking up the most disc space. This is where you're likely to find large files to get rid of.

... and if it turns out that you are truly out of space, a quick alternative is to move some large files or directories to another filesystem, then put links to the new location from root with the

ln -s

command.
( sloppy and not as fast, but works in a pinch)

then, when you have time, an ignite copy and reboot, increase size of /
