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 huxiaoyu@xxxxxxxxxxxx _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx
