Add ceph client with rbd mount To store the video data we use the existing ceph storage. We add a 10 GBE card to the server, install a ceph client, create an rbd image and mount that image as video disk into our video server and frigate container.
Restarting servers After we rebooted the cluster-12 node many virtual machines were stuck in the freezed state.
Resize placement groups (64 -> 128) The automatic algorithm now calculated an optimum of 128 placement groups, so we resize again.
Reduce placement groups After removing all movies we need to reduce the number of placement groups to 64.
Recreate smb storage (only backup) As we screw up our file storage by overloading it we need to remove all files and disks and recreate it from scratch.
Remove VMs including disks to fix storage shortage After copying to many media files onto our NAS server, so we need to free some space.
