To replace a defective OSD, delete it from UI, physically add a new disk, then in UI press + button next to the new disk and add it as OSD.
It is possible to reboot a node without doing any additional actions, since the system is highly available and will deal with failures and recoveries.
But optionally, it is better but not a must:
- Move any paths of services from node to be rebooted to another node. This is not a must, but will make client i/o freeze for a shorter time.
- In UI Maintenance menu, set the no out flag before stopping the node, and return it to normal when node is up. This is not a must, but tells Ceph not to bother initiating a recovery since you know the node will be up soon. However if the node will be down for a long time, do not do this as you do want the normal recovery ( recreating lost replica) to go on.
