Re: About Gluster cluster availability when one of out of two nodes is down

Is it not the default behavior that if a volume looses quorum, the files are still available in read-only mode?  If so, it makes sense to me that this behavior would continue after a reboot.  Otherwise the user is going to be very confused.

Currently on a two node set up, if node B goes down and node A is rebooted brick process(es) on node A doesn't come up to avoid split brains. However we have had concerns/bugs from different gluster users on the availability with this configuration. So we can solve this issue by starting the brick process(es) if quorum is not enabled. If quorum is enabled we'd not. Although quorum option really doesn't make sense in a two node cluster, but we can leverage this option to get rid of this specific situation.

I'd like to know your feedback on this and then I push a patch right away.
