Re: [ovirt-users] latest CentOS libvirt updates safe?

2016-06-27 Thread Pavel Gashev 
Upgrading libvirt doesn’t touch running VMs, if there are no active VM 
operations (start/stop/snapshots/migration). I upgrade libvirt/qemu/vdsm on the 
fly. Just stop the engine to make sure that nothing will interrupt the upgrade.

Didn't test, I think this will work:

1. Shutdown all other VMs (as you already did)
2. Move to global maintenance: hosted-engine --set-maintenance --mode=global
3. Cleanly shutdown engine vm
4. stop HA daemons: service ovirt-ha-agent stop ; service ovirt-ha-broker stop
5. yum update what you need/want
6. Reboot (perhaps not always needed)
7. See that HA daemons started
8. Exit global maintenance: hosted-engine --set-maintenance --mode=none
9. Start engine vm (or see that HA starts it)

In this case you cannot put the host into maintenance, since hosted
engine is running on this host.

The safest way is to put a host into maintenance before updating.
All vms will be migrated to other hosts before the host is deactivated.

Some packages like sanlock cannot be updated while host is connected
to storage; trying to update them may kill sanlock, which will cause the
watchdog to reboot your host, killing your vms.
