[Ocfs2-users] Fence the node when out of quorum, make FS RO instead of restart?

[Vineeth Thampi]

Hi,

On the same topic, I need to set the filesytem as OCFS2_OSB_HARD_RO
(Instead of a soft RO) in case I want to have an alternative to restart the
node in case of heartbeat failure or network failure?

Thanks,

Vineeth
