# This playbook shrinks Ceph OSDs using ceph-disk.
|
||||
#
|
||||
# It can remove any number of OSD(s) from the cluster and ALL THEIR DATA
|
||||
#
|
||||
# Use it like this:
|
||||
# ansible-playbook shrink-osd-ceph-disk.yml -e osd_to_kill=0,2,6
|
||||
# Prompts for confirmation to shrink, defaults to no and
|
||||
# doesn't shrink the cluster. yes shrinks the cluster.
|
||||
#
|
||||
# ansible-playbook -e ireallymeanit=yes|no shrink-osd-ceph-disk.yml
|
||||
# Overrides the prompt using -e option. Can be used in
|
||||
# automation scripts to avoid interactive prompt.
