I may have to recreate it -- I switched back to an all in one engine afte=
r my
setup started refusing to run the engine at all. It's no fun
losing your =
engine!

This was a migrated-from-standalone setup=2C maybe that caused additional=

I experienced the exact same symptoms as Jason on a from-scratch installati=
on on two physical nodes with CentOS 6.5 (fully up-to-date) using oVirt 3.4=
.0_pre (latest test-day release) and GlusterFS 3.5.0beta3 (with Gluster-pro=
vided NFS as storage for the self-hosted engine VM only).
I roughly followed the guide from Andrew Lau:
http://www.andrewklau.com/ovirt-hosted-engine-with-3-4-0-nightly/
with some variations due to newer packages (resolved bugs) and different ha=
rdware setup (no VLANs in my setup: physically separated networks=3B custom=
second nic added to Engine VM template before deploying etc.)
The self-hosted installation on first node + Engine VM (configured for mana=
ging both oVirt and the storage=3B Datacenter default set to NFS because no=
GlusterFS offered) went apparently smooth=2C but the HA-agent failed to st=
art at the very end (same errors in logs as Jason: the storage domain seems=
"missing") and I was only able to start it all manually with:
hosted-engine --connect-storagehosted-engine --start-poolhosted-engine --vm=
-start
then the Engine came up and I could use it=2C I even registered the second =
node (same final error in HA-agent) and tried to add GlusterFS storage doma=
ins for further VMs and ISOs (by the way: the original NFS-GlusterFS domain=
for Engine VM only is not present inside the Engine web UI) but it always =
failed activating the domains (they remain "Inactive").
Furthermore the engine gets killed some time after starting (from 3 up to 1=
1 hours later) and the only way to get it back is repeating the above comma=
nds.
I always managed GlusterFS "natively" (not through oVirt) from the commandl=
ine and verified that the NFS-exported Engine-VM-only volume gets replicate=
d=2C but I obviously failed to try migration because the HA part results in=
active and oVirt refuse to migrate the Engine.
Since I tried many times=2C with variations and further manual actions betw=
een (like trying to manually mount the NFS Engine domain=2C restarting the =
HA-agent only etc.)=2C my logs are "cluttered"=2C so I should start from sc=
ratch again and pack up all logs in one swipe.
Tell me what I should capture and at which points in the whole process and =
I will try to follow up as soon as possible.
Many thanks=2CGiuseppe
