Hi Nadiia, Although I don’t have this issue, I think you can apply the fix manually. You just need to use “cephadm exec” to get into the mgr container, and change one line of python code as in https://github.com/ceph/ceph/pull/37141/files#diff-5f6d300f6d71c1b58783257d5dc652d507376cb018f227ab6fa3521db3fc55feR467 Make backup before you do so. I have not tried this. 在 2020年11月3日,21:51,Nadiia Kotelnikova <kotelnikova9314@xxxxxxxxx> 写道: Hi, i am experience the same problem. Could you please advise something how to resolve this issue? The fix should be shipped with 15.2.6 version of "ceph-common" or ceph version? I have my cluster in docker containers and systemd services. How can I upgrade cluster to 15.2.6 if the command for upgrading fails? sudo ceph orch upgrade start --ceph-version 15.2.5 Error ENOENT: Module not found _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx
