/var/adm/crash

[ramesh_4]

Can anyone pls explain me how to set up /var/adm/crash.

Is there a way to configure it to compress /var/adm/crash while it poduces the crash.

Hi:

If you are running 11.x, a good overview is provided in /usr/share/doc/sys_crash.txt.

Hi Ramesh,

Take a look at /etc/rc.config.d/savecrash and /etc/rc.config.d/crashconf. These are the configuration files for the crashdumps made during boot time. Also check the savecrash and crashconf MAN pages.

Take a look at the file;

/etc/rc.config.d/savecrash

This has all the configurable options as to how to save a dump, if needed. Compress or not, how much space to use etc etc.

Do dump to /var/adm/crash you either need enough space on the /var filesystem (free space = memory size) or often it has its own filesystem set to the size of memory, eg. 1GB. You can create a new filesystem for it the usual way with lvcreate.

Last ensure you have the dump option set in /stand/system and build a new kernel. Most common option is dump lvol.
See man config for more info.
