Description Dan Lambright 2015-03-04 14:15:09 UTC

Description of problem:

Tiering volume creation needs to be refactored to be more like existing similar code.

We wish to form a graph that has two (sub) volumes that can be independently constructed and finally merged with tiering xlator at the root of the final graph. This is analogous to how NFS forms a graph containing separate graphs for each volume in the cluster and merges it with NFS server xlator at the root.

1. tier stop and tier status commands
2. default values for tier options
3. gluster op version < 3.7 should not write info file? If nodes are of different versions.
4. GF_CLUSTER_TYPE_MULTIPLE
