Had two Ceph pools for RBD virt disks, vm_images (boot hdd images) + rbd_data (extra hdd images). Then while adding pools for a rados GW (.rgw.*) suddenly health status said that my vm_images pool had too few PGs, thus I ran: ceph osd pool set vm_images pg_num <larger_number> ceph osd pool set vm_images pgp_num <larger_number> Kicking off a 20 min rebalancing with a lot of IO in the Ceph Cluster, eventually Ceph Cluster was fine again, only almost all my PVE VMs ended up in stopped state, wondering why, a watchdog thingy maybe... /Steffen
