Hi,
At the beginning of february I successfully installed oVirt 3.6.2 (with hosted
engine) on 3 hosts, which are using 1 storage server with GlusterFS.
2 hosts (with Intel CPU) are using HA and are hosting the engine; the 3rd host
(AMD CPU) was added as host from oVirt web administration panel, without hosted
engine deployment (I don't want the engine running on this host).
About 10 days ago I tried to reboot my oVirt environment (i.e. going to global
maintenance, shutting down the engine, turning off all the hosts, starting them
again, then setting maintenance mode to "none").
After the reboot, everything was fine with the Intel hosts and the hosted
engine, but AMD host (the one without HA) was not operational.
I tryed to activate it, buti t failed with the following error:
"Host failed to attach one of Storage Domains attached to it."
If I log into my AMD host and I check the logs, I see that the storage domain
which is not mounted is the one of the hosted engine (but this could be
correct, since this host won't run the hosted engine).

The only difference in "mount" is that the hosted-engine storage domain is not
loaded on the host which should not run the engine. The other domains are
mounted correctly.
What could I do to solve this issue?
