Hi,
there's plenty of information available online, e.g. the Red Hat docs
[1], mailing list threads [2].

Zitat von huxiaoyu@xxxxxxxxxxxx:
Dear Cepher，
We are informed that the power supply of one 10-node ceph cluster
will be cut off for a period of maintenance time. Is there a ceph
command to put Ceph in a maintenace status, so that I can safely
turn off each node of Ceph cluster?
Any suggestions, comments would be highly appreciated
best regards,
samuel
