Jewel is just around the corner and the first release candidate just came out yesterday (tagged: v10.1.0). If you are not familiar with BlueStore yet, checkout my recent article: Ceph Jewel Preview: A New Store Is Coming, BlueStore.

Start by edit your group_vars/all with the following content:

ceph_dev: true
ceph_dev_branch: v10.1.0
monitor_interface: <your interface>
public_network: <your subnet>
osd_objectstore: bluestore
ceph_conf_overrides:
  global:
    enable experimental unrecoverable data corrupting features: 'bluestore rocksdb'
    bluestore fsck on mount: true
    bluestore block db size: 67108864
    bluestore block wal size: 134217728
    bluestore block size: 5368709120

Just one more step, jump into group_vars/osds and activate the fith OSD scenario using:

bluestore: true

That’s all, now run ansible as usual: ansible-playbook site.yml. Wait a little bit and you should see the following:

$ ceph -v
 ceph version 10.1.0 (96ae8bd25f31862dbd5302f304ebf8bf1166aba6)

$ ceph -s
