Hello Proxmox Team, I'm wondering why there is no option "migrate" for the shutdown_policy available.
I looked a bit through the code and found create_migrate_worker() in PVE/API2/Nodes.pm, which is used in mass migration. Can't this be used in PVE/HA/LRM.pm when shutdown_policy = "migrate"? You know that servers take from 1 to 10 minutes to reboot. So the interruption by freezing, shutting down and starting on another node in HA setup seems not logic to me and will take a long time to recover the service. -> shutdown of databases, mounts, guest os -> shutdown of host -> start on other host Migration would keep the service running all the time - I guess in HA activated Environments online migration is mostly possible - and would also accelerate the shutdown of the host, because the VMs don't have to shut down on that host. Defining the Target Node could rely on the HA Groups priority and if not in HA you could still freeze and shutdown a VM or migrate to least used node - I remember Thomas already wrote about this and the problems behind - or even ask where to migrate. Right now the only way to keep services in HA online all the time through a node reboot, is to change the HA Group, so the service gets correctly migrated by crm. But that also has to be undone after the reboot. Okay, right now LXC came to my mind... I know there's no online migration, but am speaking for KVM now. ;-) Freeze is also applicable here. Probably it's not that easy to implement as I think on top, but do you already think of a feature like this? Or is there any other way to update my HA activated Cluster without service downtime and without the HA Group changing? Thanks so far for PVE! <3 Peace Bastian -- Bastian Sebode Fachinformatiker Systemintegration LINET Services GmbH | Cyriaksring 10a | 38118 Braunschweig Tel. 0531-180508-0 | Fax 0531-180508-29 | http://www.linet-services.de LINET in den sozialen Netzwerken: www.twitter.com/linetservices | www.facebook.com/linetservices Wissenswertes aus der IT-Welt: www.linet-services.de/blog/ Geschäftsführung: Timo Springmann, Mirko Savic und Moritz Bunkus HR B 9170 Amtsgericht Braunschweig USt-IdNr.
