[ceph-users] Removing pool in nautilus is incredibly slow

Hello, I am running ceph nautilus 14.2.8 I had to remove 2 pools (old cephfs data and metadata pool with 1024 pgs). The removal of the pools seems to take a incredible time to free the space (the data pool I deleted was more than 100 TB and in 36h I got back only 10TB). In the meantime, the cluster is extremely slow (a rbd extract takes ~1h30 mn for a 32 GB image and writing 10MB in cephfs takes half a minute !!) which makes the cluster almost unusable. It seems that the removal of deleted pg is done by deep-scrubs according tohttps://medium.com/opsops/a-very-slow-pool-removal-7089e4ac8301 Also it has been reported that this could be a regression in nautilushttps://lists.ceph.io/hyperkitty/list/ceph-users@ceph.io/thread/W4M5XQRDBLXFGJGDYZALG6TQ4QBVGGAJ/#W4M5XQRDBLXFGJGDYZALG6TQ4QBVGGAJ But I couldn't find a fix or a way to speedup (or slow down) the process and get back the cluster to a decent reactivity. Is there a way ? Thanks F.
