* mgmt/glusterd : snapshot list, minor fixes.Sachin Pandit2013-11-281-24/+75
| | | | | | | | | This patch fixes the below mentioned issue. Snapshot list : Listing number of snaps available. Display proper message if snapshot not present. Change-Id: Iabfc47430a9c89fb5114e33e9feb7ef21973fc6a Signed-off-by: Sachin Pandit <spandit@redhat.com>
* mgmt/glusterd: do not use the root of the snaped device as the brick pathRaghavendra Bhat2013-11-221-4/+24
| | | | | | | | | | | | | | | | | | Suppose a volume's brick has the path /export/brick/vol/dir and lvm of that brick is mounted at /export. Now snap of that brick is taken, and is mounted on a path (say /run/gluster/snaps/<snapname>) While creating the brick for the snap volume, /run/gluster/snaps/<snapname> (i.e the mount point of the snap lvm) should not be used as the export directory. The directory path remaining after the mount point of the original lvm should be appended to the snap lvm mounted path and should be used as the export directory (ex: /run/gluster/snaps/<snapname>/brick/vol/dir in this case). Its because the volume-id of the original volume and other extended attributes wont be set on the root. It will be in the same path as the original lvm.

* snapshot: Snapshot restoreRajesh Joseph2013-11-151-36/+709
| | | | | | | | | | | | GL-31: Ability to restore snapshot Implemented snapshot restore for thin logical volume. As of now snapshot restore for CG is not tested. Testing for snapshot restore of a volume is done by changing the snapshot create process to create a thick snapshot. This is done because --merge option to restore thin volume is not working in the latest kernel. Change-Id: Ia3ded7e6c4da5957a74e269a25ba3200e6fb2d8b Signed-off-by: Rajesh Joseph <rjoseph@redhat.com>
