Clueless about Kdump
I have 2 Linux clusters....so 4 machines.
The first 2 machines (1&2) are functioning fine, 3 & 4 are having some problems in that one of them has randomly crashed 2 or 3 times over the course of the last 2 weeks.
I was told to check for "kdumps". I read up on the KDump utility and fwiw machines 1 & 2 have the /usr/lib/debug directory and stepping down through this directory brings me to a file "vmlinux". Machines 3 & 4 have no such directory. Does that mean that Kdump is not installed/setup on 3 and 4?
How can I tell? And how can I activate it?
Also, does anyone have a clue how to analyse kdump files? (but that's probably a separate issue. Right now I just need to make sure that machines 3 & 4 have some auditing done for the next time one of them falls over.
