Re: [ovirt-users] Disabling migration when there is a problem with storage
I found that setting the cluster's 'Resilience Policy' to 'Do Not Migrate Virtual Machines' seems to have the desired effect while still letting me manually and via 'Maintenance' migrate VM's Thanks all *** *Mark Steele* CIO / VP Technical Operations | TelVue Corporation TelVue - We Share Your Vision 800.885.8886 x128 | mste...@telvue.com | http://www.telvue.com twitter: http://twitter.com/telvue | facebook: https://www.facebook.com/telvue ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users
Re: [ovirt-users] Disabling migration when there is a problem with storage
When a storage error occurs, VMs should pause, not migrate. However, if the VMs were io-idle, then pause (qemu EIO) might have not been triggered before hosts started dropping into non-op. ...which triggered a migration storm for HA-enabled VMs, racing with VMs pausing somehow (can't tell without diving into the logs for sure). I haven't seen it happen in any of my setups, probably a new issue On Wed, Feb 3, 2016 at 9:39 AM, Mark Steele wrote: > Hello, > > I'd like to know if there is a way to configure ovirt (oVirt Engine > Version: 3.5.0.1-1.el6) to NOT migrate VM's when there is a problem with > attached storage. > > Scenario - our storage array that hosts all our VM disks failed.

Re: [ovirt-users] Disabling migration when there is a problem with storage
Hi Mark, You can disable VM migration: When editing a vm, in the 'Host' tab there is 'Migration option' drop-down where you can choose 'Do not allow migration' or 'Allow manual migration only'. Hope this helps.
