<br>
I have
three nodes
with glusterfs
as storage
domain. For
some reason i
see that
vm.conf from
/var/run/ovirt-hosted-engine-h<wbr>a
is missing and
due to this on
one of my host
i see that
Hosted Engine
HA : Not
Active. Once i
copy the file
from some
other node and
restart
ovirt-ha-broker
and
ovirt-ha-agent
services
everything
works fine.
But then this
happens again.
Can some
please help me
identify why
this happens.
Below is the
log i see in
ovirt-ha-agent.logs.<br>

Once the
engine
correctly
imported the
hosted-engine
storage
domain, a
couple of
OVF_STORE
volumes will
appear there.<br>
Every
modification
to the engine
VM
configuration
will be
written by the
engine into
that
OVF_STORE, so
all the
ovirt-ha-agent
running on the
hosted-engine
hosts will be
able to
re-start the
engine VM with
a coherent
configuration.<br>
<br>
Till the
engine imports
the
hosted-engine
storage
domain,
ovirt-ha-agent
will fall back
to the initial
vm.conf.<br>
<br>
In you case
the OVF_STORE
volume is
there,<br>
but the agent
fails
extracting the
engine VM
configuration:<br>

So it tries to
rollback to

also that one
seams to miss
some values
and so the
agent is
failing:<br>

Both of the
issue seams
storage
related, could
yuo please
share your
gluster logs?<br>

Simone, i ran the following steps and i see that vm.conf file is
missing.<br>
<br>
1) Installed three nodes with glusterfs as storage domains.<br>
<br>
2) Configured power management on all the nodes and ran the command
'poweroff -f' on one of the node.<br>
<br>
3) Engine tried to fence the host and it logged the message 'Host is
rebooting' but this never came up.<br>
<br>
4) After some time i manually powered on the host and once the host
is up i see that Hosted Engine HA : Not active.<br>
<br>
5) I see the following error message in broker.log and vm.conf file
is missing.<br>
