History

John Fulton 6e7c0b6a94 Create two loop devices for bluestore and filestore The ceph-loop-device role was changed [1] to create an LVM structure on the loop device but only for versions which can use that structure for bluestore. However, the zuul.branch variable doesn't work as expected to differentiate versions so remove the code that uses it. In place of switching on the version create two loop devices, then legacy jobs which don't support LVM can use the loop device without LVM. Call the legacy loop device /dev/loop3 so older jobs get the expected name.

ceph-loop-device

This roles creates the /dev/loop3 and /dev/loop4 (default) loop devices required when you have Ceph services in the deployment. The first device is used for legacy jobs which use Ceph Filestore. The second loop device has three logical volumes created on it for use with Ceph Bluestore.

Role Variables

ceph_loop_device: /dev/loop4 ceph_loop_device_legacy: /dev/loop3 ceph_loop_device_file: /var/lib/ceph-osd.img ceph_loop_device_file_legacy: /var/lib/ceph-osd-legacy.img ceph_logical_volume_group: ceph_vg ceph_logical_volume_wal: ceph_lv_wal ceph_logical_volume_db: ceph_lv_db ceph_logical_volume_data: ceph_lv_data
