[amber]:[green]: * Almost done with: os/bluestore: allow ceph-bluestore-tool to coalesce BlueFS backing volumes [#core] https://github.com/ceph/ceph/pull/23103 Got a preliminary approval from Sage but still working on bringing in the latest updates. * Submitted : os/bluestore: debug_omit_block_device_write isn't always respected [#core] https://github.com/ceph/ceph/pull/24545 * Did some investigation and proposed the redesign to fix inability to recover from ENOSPC in BlueFS. [#core] https://tracker.ceph.com/issues/36268 https://marc.info/?l=ceph-devel&m=153935051621191&w=2 Got a positive feedback, will probably start implementing soon. * Started to track and collect information on a potential BlueStore issue which results in slow responsive OSD and high disk unitilsation under scrubbing and probably other read load. [#core] Corresponding ticket is: https://tracker.ceph.com/issues/36284 We've seen somewhat similar behavior for CONA and iirc another customer. Also I could several issues with the similar symptoms at ceph-users. Will try to investigate a bit more with Wido (guy from the community)who has suffering cluster at the moment. |
