uss/gluster: Send success on parent lookup of entry-point.

2015-01-08T09:17:13+00:00

When a lookup sent to snapview-server for entry-point directory
protocol server first tries to resolve gfid of a parent directory.

looking up the parent gfid from a latest snapshot can fail if the
volume is a restored volume. As this gfid is already looked-up by
snapview-client, we can return success for the parent gfid.

uss: CIFS gives error while accessing .snaps directory.

2015-01-08T09:16:02+00:00

CIFS sends getxattr call while accessing .snaps directory.
snapview server should return ENODATA if getxattr is called
on .snaps folder. Also flush on .snaps folder should be handled.

Windows client sends and getxattr call on the parent folder
of .snaps with a special key to get the real filename of a file.
This is used by samba to do case insensitive check of files.

Fixed few FreeBSD compilation error.

uss/gluster: Move all uss related logs into subfolder.

2014-12-19T06:53:23+00:00

For USS we have 1 snapd log per volume and as many snap logs for volume.
For example if there are 4 volumes having 256 snaps each and USS is
enabled than total number of logs under /var/log/glusterfs for USS would
be 1028 logs.

Total logs = (4(snapd per volume) + 4(volumes)*256(snaps)) = 1028

Hence, it makes sense to move into into sub-folder structure like

/var/log/glusterfs/snaps//

USS : Display only the activated snapshots.

2014-12-19T06:53:03+00:00

Instead of displaying all the snapshots in the uss world,
it is better if we display only the activated snapshots.

snapview-server: register a callback with glusterd to get

2014-09-18T17:59:30+00:00

 notifications

* As of now snapview-server is polling (sending rpc requests to glusterd) to
  get the latest list of snapshots at some regular time intervals
  (non configurable). Instead of that register a callback with glusterd so that
  glusterd sends notifications to snapd whenever a snapshot is created/deleted
  and snapview-server can configure itself.

rebase of the patch http://review.gluster.org/#/c/8150/
