[ovirt-users] Move from Gluster to NFS

Fri Feb 26 17:45:32 UTC 2016

Hi Snadro,

How can I remove the host from the engine, if I’m re-deploying the engine?

I don’t get it :)

Best,

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 ☺

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.

Kind regards,

You will not be able to move it between storage that is way I suggested the backup and restore path.

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,

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

Dear all,

I currently have a self-hosted setup with gluster on 1 node.
I do have other data centers with 3 other hosts and local (sharable) NFS storage. Furthermore, I have 1 NFS export domain.

We would like to move from Gluster to NFS only on the first host.

Does anybody have any experience with this?

Thank you,

Christophe
