Root directory full after crash

[Martin Talero]

Hi,
I have a root directory full after two crash dump on HP-UX 11.31.

Filesystem kbytes used avail %used Mounted on
/dev/vg00/lvol3 1048576 1048504 72 100% /
I can't determine where are the file created on root directory (/). I already delete the crash dump allocated on /var/adm/crash after send to HP.

Could you help me please?

[Pete Randall]

Run find:

find / -name core

then remove.

Pete thanks for your response, but I has been already deleted the crash dump allocated on /var/adm/crash after send to HP.

And there are no more core.

[Don Morris_1]

The kernel configuration at the time of the crash is typically saved to a "crashconfig" configuration under /stand. If you don't have much space for extra configurations, this could be your issue.

`kconfig` (Lists configurations -- see if there is a crashconfig listed).

`du /stand/crashconfig` (See how much space it is taking if present).

Since you already sent the crash off to HP, and especially if the crashconfig is simply your current configuration anyway (you've made no changes to tunables, patches, etc.) and you don't need the extra copy:

`kconfig -d crashconfig` (Will delete said backup crash configuration).

Shalom Martin,

/var/adm/crash is normally mounted on the /var file system and clearing the crash dump has no impact on / the root file system.

cd /

du -k | sort -rn | more

Find the big directories, make sure they are not part of mounted file systems (bdf) and find the place to look for stuff to delete.

Finding and locating core files is very likely to help with / 100% condition.

can you post the output of "ll /"?

Hi,

some open file will be there use lsof command.

If possible take one more reboot.

Hi,
I can see there is 2 directory CD and SD_CDROM check this out I think some thing is there in these directories because I can see there is no mount point in bdf output.

Post this out put

find / -size +10000 â exec ls â lrt {} \; | sort â rn | more
