Ceph OSD Service Update
From this dialog select the OSDs to be serviced. Under normal circumstances, simply restarting the ceph-osd daemon will allow it to rejoin the cluster and recover. However if an OSD is unresponsive, ensure that you have eliminated other troubleshooting possibilities before restarting OSDs.
