Hi,
If device mounted is not coming up, you can replace with new disk and ceph
will handle rebalancing the data.
Here are the steps if you would like to replace the failed disk with new
one :
1. ceph osd out osd.110
2. Now remove this failed OSD from Crush Map , as soon as its removed from
crush map , recovery process will start.
ceph osd crush remove osd.110
3.delete keyrings for that OSD and finally remove OSD
ceph auth del osd.110
ceph osd rm 110
4. Once recovery is done and ceph status is active+clean, remove the old
drive and insert new drive say /dev/sdb
5 Now create osd using ceph-deploy: (or the way you added osds at first)
ceph-deploy osd create <node>:/dev/sdb --zap-disk
Thanks
Sahana
