# This playbook was made to automate Ceph servers maintenance
|
|
|
|
|
# Typical use case: hardware change
|
|
|
|
|
# By running this playbook you will set the 'noout' flag on your
|
|
|
|
|
# cluster, which means that OSD **can't** be marked as out
|
|
|
|
|
# of the CRUSH map, but they will be marked as down.
|
|
|
|
|
# Basically we tell the cluster to don't move any data since
|
|
|
|
|
# the operation won't last for too long.
