[ceph-users] ceph rbd and pool quotas

Hi guys, quick question in regards to ceph -> rbd -> quotas per pool. I'd like to set a quota with max_bytes of a pool so that I can limit the amount a ceph client can use, like so: ceph osd pool set-quota pool1 max_bytes $(( 1024 * 1024 * 100 * 5)) This is all working, e.g., if data gets

Hi, I have problem with CephFS on writing big size file. I have found that my OpenStack Nova backup was not working after I change the rbd based mount of /var/lib/nova/instances/snapshots to CephFS based (mounted on /etc/fstab on all Nova compute nodes). I couldn't relize the cause until I tried

I guess I missed the fact that you were using the "rbd_id" object -- notifications are sent against image header "rbd_header.". A notification is only sent prior to creating a snapshot when the exclusive-lock feature is used and an active client owns the lock. Otherwise, you'll just receive an
