Created attachment 1154727 [details] renaming snap crash Description of problem: Seeing both rbd rename and rbd bench write crash when executed in parallel Version-Release number of selected component (if applicable): 10.2.0-1 How reproducible: Once Steps to Reproduce: 1. Create an RBD Image. rbd image 'testing2': size 102400 MB in 25600 objects order 22 (4096 kB objects) block_name_prefix: rbd_data.10af238e1f29 format: 2 features: layering, exclusive-lock, object-map, fast-diff, deep-flatten, journaling flags: journal: 10af238e1f29 mirroring state: disabled 2. Create 100 Snapshot. 3. Rename all snapshot for i in {1..100}; do rbd snap rename None/testing2@snappy$i None/testing2@snap$i; done 4. rbd bench-write -p None --image testing2 --io-size 10240 --io-pattern rand Run both step 3 and 4 in parallel. Actual results: Both starting execution, but after a while both "rbd snap rename" and "rbd bench-write" crashed (PFA) Expected results: There should not be any crash. PFA, both logs (bench-write.log and renaming_snap.log)
