Hi all,
I have a problem regarding upgrading Ceph cluster from Pacific to Quincy
version with cephadm. I have successfully upgraded the cluster to the
latest Pacific (16.2.11). But when I run the following command to upgrade
the cluster to 17.2.5, After upgrading 3/4 mgrs, the upgrade process stops
with "Unexpected error". (everything is on a private network)
ceph orch upgrade start my-private-repo/quay-io/ceph/ceph:v17.2.5
I also tried the 17.2.4 version.
cephadm fails to check the hosts' status and marks them as offline:

}
The strange thing is I can rollback the cluster status by failing to
not-upgraded mgr like this:
ceph mgr fail
ceph orch upgrade start my-private-repo/quay-io/ceph/ceph:v16.2.11
Would you happen to have any idea about this?
Best regards,
Reza
