At home I've a very small gluster cluster (2 nodes) with a few volumes.
Basically I've set up gluster volumes for "irreplaceable" content that
is replicated to a few systems - for example, photos. But one system is
currently out due to a failed PSU. I'd like to keep the volume
accessible to the rest of my network, but as Read Only. The
cluster.server-quorum-ratio looks to bring the volume off line if the
quorum isn't met. Since nearly all the access to these files is Read
Only anyway I can just defer the writes, is there a tunable that will
automatically put the volume into Read Only when the quorum isn't met
and then bring it back to Read Write automatically when enough bricks
check in?
tldr; cluster.server-quorum-ratio looks to bring volumes off line when
the quorum isn't met, I'd rather go Read Only than off line.
