What you could try is to increase the delete_sleep for the OSDs.
ceph tell osd.* injectargs '--osd_delete_sleep 30'
I had a customer that ran into similar issues, terrible performance on snapshot
removal. They ended up setting it to 30 to reduce the impact on performance.
You might start at a lower level and see how it affects your cluster.

Hello,
i have this state right now (see below). If i remove the nosnaptrim
flag, my IO dies and i dont know why.
When i remove all of my snapshots, will snaptrim then go away, too?
