Hi,
I've been hitting some problems with my drbd / iscsi-target clusters, resources
dropping in to FAILED (unmanaged) states etc. I'm after a bit of a sanity check
on the config below.
Firstly, I know the timesouts and intervals are lacking / too short on some
resources. I'm also looking for advice on this. It's not clear to me what an
interval
would do on a start / stop operation?
