[Gluster-users] volume start: gv01: failed: Quorum not met. Volume operation not allowed.

Hey All,

In a two node glusterfs setup, with one node down, can't use the second 
node to mount the volume.  I understand this is expected behaviour? 
Anyway to allow the secondary node to function then replicate what 
changed to the first (primary) when it's back online?  Or should I just 
go for a third node to allow for this?

Also, how safe is it to set the following to none?

cluster.quorum-type: auto
cluster.server-quorum-type: server


[root at nfs01 /]# gluster volume start gv01
