# This playbook use to recover Ceph OSDs after ssd journal failure.
|
||
# You will also realise that it’s really simple to bring your
|
||
# OSDs back to life after replacing your faulty SSD with a new one.
|
||
#
|
||
# You should define `dev_ssds` variable for host which change ssds after
|
||
# failture.
|
||
#
|
||
# For example in host_vars/hostname1.yml
|
||
#
|
||
# dev_ssds:
|
||
# - device_name: sdd
|
||
# partitions:
|
||
# - index: 1
|
||
# size: 10G
|
||
# osd_id: 0
|
||
# - index: 2
|
||
# size: 10G
|
||
# osd_id: 1
|
||
# - device_name: sdf
|
||
# partitions:
|
||
# - index: 1
|
||
# size: 10G
|
||
# osd_id: 2
|
||
#
|
||
# @param device_name: The device name of new ssd
|
||
# @param partitions: The custom partition layout of new ssd
|
||
# @param index: The index of this partition
|
||
# @param size: The size of this partition
|
||
# @param osd_id: Which osds's journal this pattition for.
