# We need many operations to remove OSDs as written in Documentation/ceph-osd-mgmt.md.
# This job can automate some of that operations: mark OSDs as `out`, purge these OSDs,
# and delete the corresponding resources like OSD deployments, OSD prepare jobs, and PVCs.
#
# Please note the following.
#
# - This job only works for `down` OSDs.
# - This job doesn't wait for backfilling to be completed.
#
# If you want to remove `up` OSDs and/or want to wait for backfilling to be completed between each OSD removal,
# please do it by hand.
