a common and often overlooked reason is to set a feasible
stop action timeout value. If this value is too small
than the stop actions times out which leads to node
stonithing.
Look at resources which might take a long time to stop
properly (even when under load). Only one example: dismou

Hello,
I'm deploying a clustered pop/imap server with mailboxes stored in a
SAN connected with fibre channel.

required for backups.
