[Linux-cluster] post_fail_delay versus deadnode_timeout



hi

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 recommended?

post_fail_delay and diskdump has come up previously, with some good answers from David
http://www.redhat.com/archives/linux-cluster/2006-June/msg00037.html

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).
