There seems to be a pretty severe bug with using hosted engine on gluster.
If the host that was used as the initial hosted-engine --deploy host goes away, the engine
VM wil crash and cannot be restarted until the host comes back.
This is regardless of which host the engine was currently running.
The issue seems to be buried in the bowels of VDSM and is not an issue with gluster
itself.
The gluster filesystem is still accessable from the host that was running the engine. The
issue has been submitted to bugzilla but the fix is some way off (4.1).
Can my hosted engine be converted to use NFS (using the gluster NFS server on the same
filesystem) without rebuilding my hosted engine (ie change domainType=glusterfs to
domainType=nfs)?
What effect would that have on the hosted-engine storage domain inside oVirt, ie would the
same filesystem be mounted twice or would it just break.
Will this actually fix the problem, does it have the same issue when the hosted engine is
on NFS?
