feature/snapshot : Interface to delete all snapshots belonging to a system as-well-as to a particular volume

2014-09-23T09:01:04+00:00

Problem :
With the current design we can only delete a single snapshot.
And the deletion of volume which contains snapshot is not allowed.
Because of that user might be forced to delete all the snapshots
manually before he is allowed to delete a volume.

Solution:
Following is the interface with which user can delete
all the snapshots of a system or belonging to a particular volume.

        Syntax : gluster snapshot delete all

        *To delete all the snapshots present in a system

        Syntax : gluster snapshot delete volume 

        *To deletes all the snapshot present in a volume specified.

========================================================================
Sample Output:

Case 1 : Deleting a single snapshot.
[root@snapshot-24 glusterfs]# gluster snapshot delete snap1
Deleting snap will erase all the information about the snap. Do you still want to continue? (y/n) y
snapshot delete: snap1: snap removed successfully

-----------------------------------------------------------------
Case 2 : Deleting all the snapshots in a Volume.
[root@snapshot-24 glusterfs]# gluster snapshot delete volume vol1
Volume (vol1) contains 9 snapshot(s).
Do you still want to continue and delete them?  (y/n) y
snapshot delete: snap2: snap removed successfully
snapshot delete: snap3: snap removed successfully
snapshot delete: snap4: snap removed successfully
snapshot delete: snap5: snap removed successfully
.
.
.

-----------------------------------------------------------------
Case 3 : Deleting all the snapshots in a system.
[root@snapshot-24 glusterfs]# gluster snapshot delete all
System contains 4 snapshot(s).
Do you still want to continue and delete them?  (y/n) y
snapshot delete: snap7: snap removed successfully
snapshot delete: snap8: snap removed successfully
snapshot delete: snap9: snap removed successfully
snapshot delete: snap10: snap removed successfully

cli/glusterd: Added support for dispersed volumes

2014-07-11T17:34:24+00:00

Two new options have been added to the 'create' command of the cli
interface:

    disperse [] redundancy 

Both are optional. A dispersed volume is created by specifying, at
least, one of them. If 'disperse' is missing or it's present but
'' does not, the number of bricks enumerated in the command
line is taken as the disperse count.

If 'redundancy' is missing, the lowest optimal value is assumed. A
configuration is considered optimal (for most workloads) when the
disperse count - redundancy count is a power of 2. If the resulting
redundancy is 1, the volume is created normally, but if it's greater
than 1, a warning is shown to the user and he/she must answer yes/no
to continue volume creation. If there isn't any optimal value for
the given number of bricks, a warning is also shown and, if the user
accepts, a redundancy of 1 is used.

If 'redundancy' is specified and the resulting volume is not optimal,
another warning is shown to the user.

A distributed-disperse volume can be created using a number of bricks
multiple of the disperse count.

mgmt/glusterd: display snapd status as part of volume status

glusterd/snapshot: Activation and De-activation of snapshot

2014-05-02T16:27:46+00:00

Previously, snapshots by default were activated on creation and there was
no option to activate or deactivate them on demand.

This will allow the user to activate and deactivate on demand.
The CLI goes as follows

1) Activate the snap using a command "gluster snapshot activate  [force]"
2) Deactivate the snap using a command "gluster snapshot deactivate "

Note: Even now the snapshot will be activated during creation.

cli: Add options to the CLI that let the user control the reset of

stats

"volume profile info" automatically clears incremental stats. There
isn't a command to:
- fetch stats without clearing incremental stats and
- clear cumulative and incremental stats

This change introduces two arguments (i.e. peek and clear). 'clear'
will wipe both incremental and cumulative stats. 'peek' fetches stats
without wiping incremental stats.

'volume profile info peek' - fetches incremental and cumulative stats
                             without wiping incremental stats

'volume profile info incremental peek' - fetches incremental stats
                                     without wiping incremental stats

'volume profile info clear' - clears both incremental and cumultiave
