Hi, first time on this list, so hi everybody! We saw these crashes with 14.2.9 and upgraded today to 14.2.10. No crashes so far since the upgrade (but it's running for only a few hours now). To answer the question: no, we don't run bluestore compression. But to add some more questioning: In the bug report/fix https://tracker.ceph.com/issues/46443 it is mentioned that this is a bug in the linux kernels monotonic timer implementation. However it is not mentioned if this was ever reported to the upstream linux kernel, or if there is a fix available for the kernel itself. Has anyone information regarding a bug report against the kernel? Did someone very this bug against the latest upstream kernel? If this is not the case, we will try to reproduce with upstream and possibly report it as a bug, because I think it is important to fix this upstream (if it is a problem with non distro kernels). -- Mit freundlichen Grüßen / Regards Sven Kieske Systementwickler Mittwald CM Service GmbH & Co.
