Hi folks,

We need add on left side New tab - Manage Cluster tab

Please add on Manage Cluster tab - button Start Maintenance and Stop Maintenance (periodically, you may need to perform maintenance on a subset of your cluster, or resolve a problem that affects a failure domain (e.g., a rack). If you do not want CRUSH to automatically rebalance the cluster as you stop this process for maintenance).

Start Maintenance button has execute next commands (install ceph flags):

ceph osd set noout

ceph osd set nodown

ceph osd set noup

ceph osd set norecover

Stop Maintenance button has execute next commands (remove ceph flags):

ceph osd unset noout

ceph osd unset nodown

ceph osd unset noup

ceph osd unset norecover

Also need additionally verify this situation(automatically rebalance) before reboot/shutdown from console.
