Subject: [pve-devel] [PATCH-SERIES ha-manager] avoid rebalance-on-start for newly added already running service
Date: Fri, 14 Apr 2023 14:38:26 +0200	[thread overview]
Message-ID: <20230414123830.60720-1-f.ebner@proxmox.com> (raw)

As reported in the community forum[0], the current behavior when
adding an already running service to HA is wrong. If rebalance
selected a different node, the service would be stopped, offline
migrated and started again. Since the rebalance-on-start is only
intended to trigger on the stopped->start transition[1], this series
makes sure the service is not migrated at all for rebalance-on-start
if already running.
