Hi,
I have some issues with hosted engine (oVirt 3.4 prerelease repo on
CentOS 6.5).
My setups is the following:
2 hosts (will be 4 in the future) with 4 GlusterFS shares:
- engine (for hosted engine)
- iso (for ISO domain)
- ovirt (oVirt storage domain)
I had a split-brain situation today (after rebooting both nodes) on
hosted-engine.lockspace file on engine GlusterFS volume which I resolved.
hosted engine used engine share via NFS (TCP) as glusterfs isn't
supported for oVirt hosted engine, yet. I'll switch to GlusterFS as soon
as oVirt will support it (I hope this will be soon as RHEV 3.3 is
already supporting GlusterFS for hosted engine).
First of all ovirt-ha-agent fails to start on both nodes:
# service ovirt-ha-agent start
Starting ovirt-ha-agent: [ OK ]
# service ovirt-ha-agent status
ovirt-ha-agent dead but subsys locked

If I want to start my hosted engine, I receive the following error in
vdsm logs, which makes absolutly no sense to me, as there is plenty of
disk space available:

Could you give me some information on how to fix the ovirt-ha-agent and
then hosted-engine storage issue? Thanks a lot.
Btw, I had some issues during installation which I will explain in
separate emails.
