Public bug reported: Hi,
The bug is as mentioned in the Ceph upstream: https://tracker.ceph.com/issues/67221 and also Linux upstream: https://github.com/torvalds/linux/commit/ccda9910d8490f4fb067131598e4b2e986faa5a0 Under some situations, the libcephfs forgets the acquired capabilities and thus gets evicted by the Ceph MDS. I would like to see if a backport will be available for Ubuntu 22.04 LTS (Jammy) Ceph Quincy client (17.2.x). Logs on the client: Dec 19 04:32:45 *** kernel: libceph: mds0 (1)***:6801 socket closed (con state OPEN) Dec 19 04:32:46 *** kernel: libceph: mds0 (1)***:6801 session reset Dec 19 04:32:46 *** kernel: ceph: mds0 closed our session Dec 19 04:32:46 *** kernel: ceph: mds0 reconnect start Dec 19 04:32:46 *** kernel: ceph: mds0 reconnect denied Dec 19 04:32:46 *** kernel: libceph: mds0 (1)***:6801 socket closed (con state V1_CONNECT_MSG) Dec 19 04:32:47 *** kernel: ceph: mds0 rejected session Logs on the server: Dec 19 04:30:17 *** ceph-mds[1408372]: log_channel(cluster) log [WRN] : client.911386 isn't responding to mclientcaps(revoke), ino 0x1004e6bede5 pending pAsLsXsFs issued pAsLsXsFs, sent 240.313055 seconds ago Dec 19 04:32:44 *** ceph-mds[1408372]: log_channel(cluster) log [INF] : Evicting (and blocklisting) client session 911386 (v1:***:0/362122962) The Ubuntu client version: Description: Ubuntu 22.04.5 LTS Release: 22.04 Package: libcephfs2/jammy-updates,jammy-security,now 17.2.7-0ubuntu0.22.04.2 amd64 [installed,automatic] What expected to happen: * There shall be no 'client isn't responding to ... pending pAsLsXsFs ...' messages, and no eviction. What happened instead: * The error appeared and the client is evicted.
