Being a gumby on Linux, i have a couple of questions about the root disk. I am from a Solaris background.

How is it partitioned up ? Do you use 8 partitions like Solaris ?

Are the filesystems the same ? (/var, /opt, /home, etc) ??

Where is a crash dump stored (/var/crash ???)

Where are the log files stored (/var ???)

I will STFW but need some info vvv quick.

Hi,

I'll try to help a bit...

I think linux is stuck with 16 partitions on the same HD. The filesystems are similar to solaris, e.g. /var, /opt, /etc, etc.etc..

For crash dumps, see http://www.linux.org/docs/ldp/howto/Linux-Crash-HOWTO/howitworks.html.

hen a kernel encounters certain errors it calls the "panic" function which results from a unrecoverable error. This panic results in LKCD initiating a kernel dump where kernel memory is copied out to the pre-designated dump area. The dump device is configured as primary swap by default. The kernel is not completely functional at this point, but there is enough functionality to copy memory to disk. After dump finishes copying memory to disk, the system re-boots. When the system boots back up, it checks for a new crash dump. If a new crash dump is found it is copied from the dump location to the file system, "/var/log/dump" directory by default. After copying the image, the system continues to boot normally and forensics can be performed at a later date.

Same deal as solaris, it writed system cores to /var/log/dump

log files are all stored in /var/log.

Hope this helps a bit...

Cheers Dave, that is very helpful. Am installing RedHat AS 2.1 to be specific.

It's getting a bit too sunny. Time to get the beers from the fridge, methinks.
