Hi,
I have tried these steps :
- Stop Hosted VM
- # vdsClient -s localhost forcedDetachStorageDomain <hosted_storage domain>
- Domain is now detached
- # hosted-storage –clean-metadata
- # hosted-storage –vm-start
But, hosted domain path is still the old one.
If I run :
# vdsClient -s localhost getStorageDomainsList <hosted_storage domain>
The path is correct !!
So I don’t know where the wrong path is stored.
If the engine imported the hosted-engine storage domain in the past, that storage domain is in the engine DB with the wrong path. If you bring down everything and reboot your hosts, ovirt-ha-agent will mount the hosted-engine-storage domain with the new path under hosted-engine.conf. At this point ovirt-ha-agent can start the engine VM. When the engine will come up it will try to mount all the storage domain in the datacenter as for regular hosts. This will mean that it will try to remount also the hosted-engine storage domain (cause the domain uuid is the same!) from the old path since it's still configured like that in the engine DB.
I think the only way is to reinstall Hosted VM from scratch.
You can try to manually force a new path in the DB.
@ Staniforth Paul, your procedure is not working L

Hi,
Path is neither shared not mounted anymore on previous NFS server, but storage domain is still up and cannot be removed…
Is there a possibility to remove it from command line ?

Hi,
I am not able to do that, "Remove" button is greyed. And it is not possible to place it into maintenance mode because hosted VM is running on it...
Any clue?
You must create a situation where vdsm would fail to monitor that domain. I.e stop sharing that path or block it and then the status will allow you to force remove
Thanks.

Hi,
I have followed these steps :
- Stop supervdsmd + vdsmd + ovirt-ha-agent + ovirt-ha-broker
- Modify config file
- Copy files (cp better handles sparse files than rsync)
- Umount old hosted-engine path
- Restart services
- Hosted VM doesn’t start => hosted-engine –clean-metadata. I get an error at the end, but now I am able to start Hosted VM :
o ERROR:ovirt_hosted_engine_ha.agent.hosted_engine.HostedEngine:Metad ata for current host missing.
I can connect to oVirt interface, everything seems to be working fine, but the Hosted storage domain has an incorrect path, it is still pointing to old one… I think this information is not correctly reported by web interface, because this path doesn’t exist anymore, and hosted VM is working !
Does anyone knows how to fix that ?
You have to do a "force remove" in the UI (without clicking the destroy checkbox) of that storage. Then it should be reimported automatically.

Hi,
I’m trying to move Hosted storage from one NFS server to another.
As this is not a production environment, so I gave a try with no success, with a plan similar to yours.
But I don’t like to stay on a failure, so I will give a second chance by following your plan J

Hello,
we would like to move our NFS storage used for the HostedEngine.
Plan would be
enable global maintenance shut-down HostedEngine VM edit /etc/ovirt-hosted-engine/hosted-engine.conf on hosts
storage=newnfs:/newnfsvolume
copy storage domain from old to new nfs server start HostedEngine VM run engine-setup on HostedEngine VM disable global maintenance
Has anyone had any experience doing this?
Have I missed any steps out
we are currently running oVirt 3.6.2
Thanks,
Paul S.
