Hi everyone, it seems there have been several reports in the past related to BlueStore OSDs crashing from unhandled errors in _txc_add_transaction:
http://lists.ceph.com/pipermail/ceph-users-ceph.com/2019-April/034444.html http://lists.ceph.com/pipermail/ceph-users-ceph.com/2019-January/032172.html http://lists.ceph.com/pipermail/ceph-users-ceph.com/2018-December/031960.html http://lists.ceph.com/pipermail/ceph-users-ceph.com/2018-December/031964.html Bug #38724 tracks this, has been fixed in master with https://github.com/ceph/ceph/pull/27929, and is pending backports (and, I dare say, is *probably* misclassified as being only minor, as this does cause potential data loss as soon as it affects enough OSDs simultaneously): https://tracker.ceph.com/issues/38724 We just ran into a similar issue with a couple of BlueStore OSDs that we recently added to a Luminous (12.2.12) cluster that was upgraded from Jewel, and hence, still largely runs on FileStore. I say similar because evidently other people reporting this problem have been running into ENOENT (No such file or directory) or ENOTEMPTY (Directory not empty); for us it's interestingly E2BIG (Argument list too long): https://tracker.ceph.com/issues/38724#note-26 So I'm wondering if someone could shed light on these questions: * Is this the same issue as that which https://github.com/ceph/ceph/pull/27929 fixes? * Thus, since https://github.com/ceph/ceph/pull/29115 (the Nautilus backport for that fix) has been merged, but is not yet included in a release, do *Nautilus* users get a fix in the upcoming 14.2.3 release, and once they update, would this bug go away with no further intervention required? * For users on *Luminous*, since https://tracker.ceph.com/issues/39694 (the Luminous version of 38724) says "non-trivial backport", is it fair to say that a fix might still take a while for that release? * Finally, are Luminous users safe from this bug if they keep using, or revert to, FileStore? Thanks in advance for your thoughts! Please keep Erik CC'd on your reply.
