I am suspecting that there is a bug in 12.2.8-0ubuntu0.18.04.1. We have too ceph client n01 and n03 with following software versions.
# n01 ceph-common: Installed: 12.2.8-0ubuntu0.18.04.1 Candidate: 12.2.12-0ubuntu0.18.04.2 # n03 ceph-common: Installed: 12.2.11-0ubuntu0.18.04.2 Candidate: 12.2.12-0ubuntu0.18.04.2 # n01 uname -a Linux n01 4.15.0-43-generic #46-Ubuntu SMP Thu Dec 6 14:45:28 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux # n03 uname -a Linux n03 4.15.0-54-generic #58-Ubuntu SMP Mon Jun 24 10:55:24 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux Problem: N01 can mount its RBD after reboot whereas N03 can’t. To verify that it is something on client side, I upgrade n01 to have the same package version to n03 including ceph-common. And n01 does indeed fail to mount its CEPH RBD partition. Syslog shows messages like the following: Sep 6 12:52:33 n01 kernel: [ 875.160275] rbd: rbd0: no lock owners detected Sep 6 12:52:33 n01 kernel: [ 875.161069] rbd: rbd0: client2508785 seems dead, breaking lock Sep 6 12:52:33 n01 kernel: [ 875.161723] rbd: rbd0: blacklist of client2508785 failed: -13 Sep 6 12:52:33 n01 kernel: [ 875.161724] rbd: rbd0: failed to acquire lock: -13 Sep 6 12:52:33 n01 kernel: [ 875.161956] rbd: rbd0: no lock owners detected Sep 6 12:52:33 n01 kernel: [ 875.162755] rbd: rbd0: client2508785 seems dead, breaking lock Sep 6 12:52:33 n01 kernel: [ 875.163415] rbd: rbd0: blacklist of client2508785 failed: -13 Sep 6 12:52:33 n01 kernel: [ 875.163415] rbd: rbd0: failed to acquire lock: -13 Sep 6 12:52:33 n01 kernel: [ 875.163645] rbd: rbd0: no lock owners detected Sep 6 12:52:33 n01 kernel: [ 875.164431] rbd: rbd0: client2508785 seems dead, breaking lock Sep 6 12:52:33 n01 kernel: [ 875.165082] rbd: rbd0: blacklist of client2508785 failed: -13 Sep 6 12:52:33 n01 kernel: [ 875.165082] rbd: rbd0: failed to acquire lock: -13 Sep 6 12:52:33 n01 kernel: [ 875.165355] rbd: rbd0: no lock owners detected [signature_1482564062] Vang Quy Le Special Consultant in Data Science and Infrastructure T: (+45) 9940 7710 | Email: [email protected]<mailto:[email protected]> Kontor 0-1-91 | Selma Lagerløfs Vej 300 | DK-9220 Aalborg Ø |
