this. The first is if you are using a lot of snapshots. Deleting
snapshots is a very expensive operation for your cluster and can cause a

We have been having similar performance issues across several ceph
clusters. When all the OSDs are up in the cluster, it can stay HEALTH_OK
for a while, but eventually performance worsens and becomes (at first
