[pve-devel] [PATCH ha-manager 1/4] fix #7133: manager: group migration: skip update for resources without group

[Daniel Kral]

The HA group migration is executed if the HA groups config is still
present in the HA config directory and individually updates every HA
resource, even if none of those are part of a HA group.

The call to update_service_config(...) for the HA resources without
group assignments cause unnecessary updates to the config and can become
costly with higher HA resource counts, which might prevent the CRM to
update its watchdog in time, so skip these updates.
