Cinder has added support for creating and managing volume consistency
groups. This first patch adds this functionality into Horizon.
Subsequent patches will add features to utilize these consistency
groups - such as for creating snapshots.
Background/setup info:
This feature provides a Horizon interface to the Cinder consistency
groups (CG) API. CGs allow a user to group a set of volumes together,
and then perform actions on all of the volumes in one command.
For example:
- Create CG snapshot. This will pause all volume I/O and create a
snapshot for each volume in the CG at the same point in time.
- Create CG from another CG. This will clone a new set of volumes based
on the current state of all volumes in the original CG.
- Create CG from CG snapshot. This will clone new set of volumes based
on the saved state of all snapshots from the original CG snapshot.
This patch is limited to just creating consistency groups. A second
and final patch will add the snapshot features.
To run the patch, you will need to enable some consistency group
policies, which currently are defaulted to "none", which means they
are disabled.
The policies are set in /etc/cinder/policy.json - they need to be set
to the following:
"consistencygroup:create" : "rule:admin_or_owner",
"consistencygroup:delete": "rule:admin_or_owner",
"consistencygroup:update": "rule:admin_or_owner",
"consistencygroup:get": "rule:admin_or_owner",
"consistencygroup:get_all": "rule:admin_or_owner",
"consistencygroup:create_cgsnapshot" : "rule:admin_or_owner",
"consistencygroup:delete_cgsnapshot": "rule:admin_or_owner",
"consistencygroup:get_cgsnapshot": "rule:admin_or_owner",
"consistencygroup:get_all_cgsnapshots": "rule:admin_or_owner",
Once this is done, you will need to restart all 3 of the cinder
services in "screen -r" (c-api, c-sch, and c-vol).
The new panel is a tab named "Volume Consistency Groups" and is
located in "Project -> Volumes".
