Hello list, After running cache tiers for years and years, we decided to turn off caching on a mostly dormant cluster. Given an installation using Pacific, we followed the instructions as dictated on: https://docs.ceph.com/en/pacific/rados/operations/cache-tiering/#removing-a-... So, we set the "hot" tier to cache-mode proxy (as the documentation mentions) and simply waited for a bit. Since nothing really seemed to happen, we did a manual flush using cache-flush-evict-all (also as the documentation mentions). So far, so good. The end result is a cache tier with still quite some (>81k) objects within. Running cache-flush-evict-all again renders errors such as: failed to flush /rbd_data.d9d54166ef438d.0000000000020899: (2) No such file or directory rbd_data.d9d54166ef438d.000000000001a511 This is not what is expected. What are we looking at? And, how to move forward in removing the cache? Thanks for your help and wisdom! Cheers, Kees P.S. The introduction text speaks of readproxy and not proxy. This confusing since the instruction text speaks of proxy.
