I tried to flush the cache with "rados -p cache-bkp-foo cache-flush- evict-all", but it blocks on the object "rbd_data.f66c92ae8944a.00000000000f2596".
This is the object that's stuck in the cache tier (according to your output in https://pastebin.com/zrwu5X0w). Can you verify if that block device is in use and healthy or is it corrupt?

Could you, please paste the output of pg 37.9c query pt., 21 wrz 2018 o 14:39 Olivier Bonvalet <ceph.l...@daevel.fr> napisał(a):In fact, one object (only one) seem to be blocked on the cache tier (writeback). I tried to flush the cache with "rados -p cache-bkp-foo cache-flush- evict-all", but it blocks on the object "rbd_data.f66c92ae8944a.00000000000f2596". So I reduced (a lot) the cache tier to 200MB, "rados -p cache-bkp-foo ls" now show only 3 objects : rbd_directory rbd_data.f66c92ae8944a.00000000000f2596 rbd_header.f66c92ae8944a And "cache-flush-evict-all" still hangs. I also switched the cache tier to "readproxy", to avoid using this cache. But, it's still blocked.
