Yesterday my ceph nautilus 14.2.15 cluster had a disk with unreadable
sectors, after several tries the OSD was marked down and rebalancing
started and has also finished successfully. ceph osd stat shows the osd
now as "autoout,exists".
Usually the steps to replace a failed disk are:
1. Destroy the failed OSD: ceph osd destroy {id}
2. run ceph-volume lvm create --bluestore --osd-id {id} --data /dev/sdX
... with a new disk in place to recreate a OSD with the same id without
the need to change the crushmap or auth info etc.
Now I still wait for a new disk and I am a unsure if I should run the
destroy-command already now to keep ceph from trying to reactivate the
broken osd? Then I would wait until the disk has arrived in a day or so
and then use ceph volume to create a new osd?
If the rebalance is complete, then I would destroy the old OSD now - as
you say, if the system reboots or somesuch you don't want the OSD to try
and restart on a fail{ed,ing} disk.
