Hi all, I have a cluster used purely for storing rbd images. I spent the last few days tracking down why the increase in storage did not match what I imported, and found it was caused by this: $ sudo rbd rm test-root 2016-12-21 14:46:38.479281 7fa1e17d8760 -1 librbd: Image uses unsupported features: 48 Removing image: 100% complete...done. $ echo $? $ 0 Checking with rbd df before and after I noticed that only one object was deleted (probably the header) and the total usage did not decrease. The scripts that I used only checked the return code of rbd so assumed successful deletion. Run them enough times and suddenly you're wondering where 100TB has gone... A bit of background, the cluster runs Jewel, but the rbd client used to delete these images was the one from Hammer. I was wondering if this is a known issue?
