We are trying to capture diskdumps when a lock_dlm kernel panic happens
and need to increase either post_fail_delay or deadnode_timeout to
prevent the dumping node from being fenced.
Is there any advantages or disadvantages to using either? Which is
post_fail_delay and diskdump has come up previously, with some good
answers from David
note: for capturing a "sysrq t", we manually increase deadnode_timeout,
and decrease it back again, but don't have this luxury with a kernel
panic (which can happen at any time).
