[Gluster-users] failover

[Lindsay Mathieson]

You probably have quorum problems – with 2 nodes its not safe to write to a node when one is down due to the possibility of it being up but uncontactable, so potentially both nodes could be written too, leading to split brain issues.

Ideally you should setup three nodes, replica 3 with client quorum enabled. So long as any *two* nodes stay in contact, they can be written to.

Alternatively two nodes plus one arbiter node will work as well.

Hi,
I am just testing a KVM frontend with VMs and using a backend 2 node gluster setup mount with glusterfs.  this runs fine, but my understanding was that if the gluster node the front end is attached to goes down the client swaps to the other node and carries on?
So I switched gluster node 1 off and the VM just froze, so I am missing something?  or am I wrong and it cant autofailover?
