Hi everyone,
If I choose to use the "non-collocated" scenario and Bluestore in
Ceph-Ansible, how could I define the size of the partitions on a
dedicated device used for the DB and WAL by multiple OSDs?
Like this in global_vars:
ceph_conf_overrides:
global:
bluestore_block_db_size: "{{
hostvars[inventory_hostname]['ceph_bluestore_block_db_size'] |
default('32212254720') }}"
bluestore_block_wal_size: "{{
hostvars[inventory_hostname]['ceph_bluestore_block_wal_size'] |
default('1073741824') }}"
Now you can define wal/db sizes for each host via
'ceph_bluestore_block_db_size' and 'ceph_bluestore_block_wal_size' or
use defaults (1Gb for wal, 28Gb for db).
