space issue regarding /var/adm/crash

[sanjayhp]

Hello,

Thank you in advance. In HP-UX 11.31 /var space is created 8GB. My memory is 12GB. Can any body explain,

/var/adm/crash space occupation if any crash dump happened?

As i understood from fourms that 25% of RAM space could be suffiecent for /var/adm/crash,

does 8 GB space for /var sufficient along with crash in /var/adm/crash?

Thak you

Sanjay

Hi Sanjay,

Yes, 8GB of space in /var is sufficient for crash dump of /var/adm/crash mount point.

It is still a good practise to create the mount point of /var/adm/crash with a size of 25% of RAM space if you the luxury of space.

In our system with 30GB LUN for the root disk, we have 8GB of space for /var and the system has not complaint even when there were crash.

Thanks,
Srikanth

Depends what leads up to the crash. A large amount of system activity may write a lot of data to log files in /var. I would always recommend having /var/adm/crash in a dedicated lvol.
