Hi,
you should unpause your cluster (ceph osd unpause) so all services can
read again. The other flags are probably also safe to unset since all
OSDs seem to be up.
Regards,
Eugen

Hi all,
I have 4-nodes ceph cluster.
After I shutted down my cluster, I tried to start it again, but failed due
to
ceph orch xxx (such as status) commands hung.
How sould I recover from this problem ?
root@ceph-manager:/# ceph orch status ==> hung
