Ceph disk upgrade procedure
- I will use osd.32 in this example
- Find your OSD physical device path (/dev/sdxx)
cephadm ceph-volume lvm list
Look for devices section next to ====== osd.32 =======
Mine is /dev/sdaj - Mark OSD for an upgrade as out. Data will be moved off it to other disks in the cluster.
ceph osd out 32 - Remove OSD from cluster.
ceph orch osd rm 32 - Optional: Wipe LVM from the device
ceph orch device zap [servername] /dev/sdaj --force - Optional: Shred the data on the device
shred -n0 -vfz /dev/sdaj - Remove the device and insert the new one into the server
- Create OSD for new disk
ceph orch daemon add osd [servername]:data_devices=/dev/sdaj - All done
