[ovirt-users] Moving Hosted Engine NFS storage domain

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:Metadata 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 ?
Regards,
Lionel BEARD

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 :)

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.
