[Ocfs-users] OCFS Questions

[Wim Coekaerts]

if you have a few controllers so that there are multiple queues you
should be ok.

run     vmstat 1 10 when not much is going on and email that ?
if you have no io wait if oracle is not running but it's just mounted,
little or a lot of io won't be a problem
