does the broker automatically sync the change you made in /etc/ovirt-hosted-engine/hosted-engine.conf to the other ha hosts or did you omit a step? On 6 November 2014 11:10, Groten, Ryan <Ryan.Groten@stantec.com> wrote:
I went through this a couple months ago. Migrated my hosted-engine from one NFS host to another. Here are the steps that I documented from the experience. There is probably a better way, but this worked for me on two separate hosted-engine environments.
1. Make a backup of RHEV-M 2. Migrate VMs off all hosts that run hosted-engine (except hosted-engine itself) 3. Put hosted-engine hosts in maintenance mode (except host that's running hosted-engine) 4. Put hosted-engine in global maintenance mode 5. Shutdown hosted-engine 6. Stop ovirt-ha-agent and ovirt-ha-broker services on all hosted-engine hosts 7. On each hosted-engine host: a. service ovirt-ha-agent stop b. service ovirt-ha-broker stop c. sanlock client shutdown -f 1 d. service sanlock stop e. umount /rhev/data-center/mnt/<hosted-engine-share> f. service sanlock start 8. mount new NFS share on /hosted_tgt 9. mount old NFS share on /hosted_src 10. Copy data (make sure sparse files are kept sparse): a. rsync --sparse -crvlp /hosted_src/* /hosted_tgt/ 11. Edit /etc/ovirt-hosted-engine/hosted-engine.conf and change path: storage=10.1.208.122:/HostedEngine_Test 12. Make sure permissions are vdsm:kvm in /hosted_tgt/ 13. umount /hosted_tgt 14. umount /hosted_src 15. Pick one hosted-engine host and reboot, then run: a. hosted-engine --connect-storage (make sure the new NFS is mounted properly) b. hosted-engine --start-pool (wait a few seconds then try again if you get an error) c. service ovirt-ha-broker start d. service ovirt-ha-agent start e. hosted-engine --vm-start

So is this the workflow?
set the hosted-engine maintenance to global shutdown the engine VM make changes via virsh or editing vm.conf sync changes to the other ha nodes restart the VM set hosted-engine maintenance to none
- well, not official, because it can cause a lot of troubles, so I would not recommend it unless you have a really good reason to do it.
I'd like to move my ovirt-engine VM to a new NFS storage. I was thinking to adopt this workflow for this use-case (in combination with rsync to mirror the old storage).
Do you think this would succeed or is there another (and maybe "supported") way to move ovirt-engine to a different storage?
