deploy it on a second host, restore the backup, remove the first host from
the engine and then re-add it.

We're discussing this kind of migrations with storage guys. We haven't a
supported procedure to do this yet.
Above procedure should work except that if you're going to re-use the first
host you'll need to remove it from the engine before trying to attach it
again from he-setup.

We will probably need to backup and restore the HE vm after doing a clean
install on NFS.

Re: [ovirt-users] Move from Gluster to NFS

[Christophe TREFOIS]

Hi Yaniv,

Would you recommend doing a clean install or can I simply move the HE from the 
gluster mount point to NFS and tell HA agent to boot from there?

What do you think? 

Thank you,

Re: [ovirt-users] Move from Gluster to NFS

[Christophe TREFOIS]

Is there a reason why this is not possible?

Can I setup a second host in the engine cluster and move the engine with 
“storage” to that host?

So, what you would recommend is:


1.   Move all VMs from engine host to another Host

2.   Setup NFS on the empty HE host

3.   Shutdown the HE, and disable HA-proxy and agent

4.   Re-deploy the engine and restore from backup the HE

5.   Enjoy ?

Thank you for any help on this,
I really don’t want to end up with broken environment ☺

Kind regards,
