Re: [ovirt-users] hosted engine deploy failed 3.5 centos 6.5 host FC20 vm

29 Oct 2014

      OK I seem to be having some fundamental confusion about this migration.

I have an existing ovirt 3.5 (upgraded from 3.4) setup with  a Data Center
containing four clusters, 3 VM clusters for 3 differenc classes of CPU
hosts (Penryn, Nehalem, and SandyBridge).  I also have a  gluster storage
cluster.

There are 4 storage domains, an Export domain (Export-Dom1) nfs v1, and ISO
domain (Gluster-ISOs) posix FS v1, a Data domain (Gluster Data) GlusterFS
V3, and a Data (Master) (Gluster-VM-Store) GlusterFS v3.

As Gluster replica 2 is not considered adequate for the hosted-engine
storage I created a volume in the gluster store and exported it as NFS.
This is what I planned to use as the storage pool for the hosted engine.
So far so good.

I have tried the deployment several times now,  and it fails with the
following:

RuntimeError: Cannot add the host to cluster None
The hosted-engine host cluster name it seems is set to "None", and then
fails to add the host as there is no cluster "None" in the restored
engine.  Presumably the storage domain would need to be added too, however
I don't ever seem to see any message about this

I recall being prompted for a data-center name and even a storage-domain
name, but not a cluster name, so am I missing a step.  I could use some
guidance as I am stumped.  Is there some pre-migration tasks I am failing
to do in the original engine?

After belatedly realising that no engine for EL7 is planned for 3.5 I
tried using FC20:
I used a database called engine with user engine on the VM to restore to.
The engine-backup restore appeared to complete with no errors save the
canonical complaint about less that 16GB of memory being available.
However on completion the host the hosted-engine-deploy threw this error:
Failed to execute stage 'Closing up': The host name
    "ovirt-admin-hosted.xxxxx.xxx.edu

I have a functional copy of my original engine in the VM but it is not
hosted.
Any ideas/Pointers?
- seems like you're restoring the engine on machine with different URL, so
the certificates from the backup don't match
