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 =3D> hosted-engine -clean-metadata. I ge=
t 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 ol=
d one... I think this information is not correctly reported by web interfac=
e, because this path doesn't exist anymore, and hosted VM is working !
Does anyone knows how to fix that ?

Objet : RE: Moving Hosted Engine NFS storage domain

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, w=
ith a plan similar to yours.

But I don't like to stay on a failure, so I will give a second chance by fo=
llowing your plan :)

Objet : [ovirt-users] Moving Hosted Engine NFS storage domain

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=3Dnewnfs:/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.

I can conn=

 storage domain has an incorrect path, it is still
 pointing to old one… I think this information is not correctly repor=
