[ovirt-users] Moving hosted engine storage
I'm moving a 4.3 cluster to new storage, and I'm down to the hosted engine. I am reading the following: https://www.ovirt.org/documentation/migrating_from_a_standalone_manager_to_a_self-hosted_engine/ https://www.ovirt.org/develop/developer-guide/engine/migrate-to-hosted-engine.html https://lists.ovirt.org/pipermail/users/2017-January/078739.html The last mentions a couple of options added to engine-backup to filter out the old hosted engine parts, but where do I use them? It looks like they only apply during restore, but from the last time I rebuilt the engine (mvoing from CentOS 6 to CentOS 7), I thought I just provided the backup file to hosted-engine --deploy and it handled the restore. Is there a way to pass those options to hosted-engine --deploy, or should I do like the example and just deploy a brand new engine, then log in and manually apply the backup (and filter options) then? Just trying to make sure I understand current (well, current for 4.3) best practice for replacing the hosted engine's storage array (iSCSI in this case, if that matters). -- Chris Adams ___ Users mailing list -- users@ovirt.org To unsubscribe send an email to users-le...@ovirt.org Privacy Statement: https://www.ovirt.org/privacy-policy.html oVirt Code of Conduct: https://www.ovirt.org/community/about/community-guidelines/ List Archives: https://lists.ovirt.org/archives/list/users@ovirt.org/message/YTBWNAOZB6TXTSP2RCDUIE4MQHMUILXC/
[ovirt-users] Moving Hosted Engine Storage
Hello, I've read various posts[1] on this list, but I must confess that I am still not entirely clear on the process for moving a hosted engine to a new storage domain (in my case I want to move from an existing NFS server to a new iSCSI target). Some of what i've read make me slightly concerned it's a risky operation and in my situation I am just prototyping and retaining the existing engine will be saving some time rather than mission critical. Is anyone able to outline the steps to me? thanks, Dan [1] https://lists.ovirt.org/pipermail/users/2017-June/082466.html The Networking People (TNP) Limited.

Re: [ovirt-users] Moving hosted engine storage
Hi Garry, unfortunately it is not so easy. The ovirt-engine instance has a record with the storage domain setup that needs to be modified. You also have to tell VDSM to mount the storage domain from a different place. And you will probably have to restart all the affected hosts at the same time to do that cleanly. I am CCing Sandro who is maintaining the hosted-engine-setup tool and probably knows more about where else is the storage domain location stored. -- Martin Sivák msi...@redhat.com Red Hat Czech RHEV-M SLA / Brno, CZ - Original Message - Hi guys, Has anyone successfully moved hosted-engine before? I built 3.4 hosted-engine on CentOS a couple of weeks back, over gluster NFS with a keepalived, per Andrew's procedure. I want to switch to kernel NFS on localhost:/hosted-engine, and retain gluster underneath, just for mirroring. Should have been simple, drop gluster NFS, mount the glusterfs locally on each host, alter hosted-engine.conf, fire up hosted-engine. Not so good, the all-zeros storage pool just wouldn't come online. I have logs, though anyone who recognises this would know it without. I have a few other vms running, isolated on one host for convenience. A rebuild is not out of the question. Would appreciate any pointers from the community.
