snapshot/cli: Fix snapshot status xml output

2016-08-23T07:11:54+00:00

snap status --xml errors out if a brick is down and
doesn't have pid. It is handled in the cli of the snap
status where "N/A" is displayed in such a scenario.
Handled the same in xml

snap status  --xml fails as the writer is
not initialised for the same. Using GF_SNAP_STATUS_TYPE_ITER
instead of GF_SNAP_STATUS_TYPE_SNAP for all snap's
status to differentiate between the two scenarios.

Added testcase volume-snapshot-xml.t to check
all snapshot commands xml outputs

Snapshot/xml:xml output for snapshot clone

2016-07-29T10:09:41+00:00

Snapshot clone is used to create a regular volume from snapshot.
Currently snapshot clone is not supporting xml outout.

This change introduce a xml output for snapshot clone command

glusterd/snapshot: free resource from the owner of memory

2016-06-14T10:47:48+00:00

We are freeing memory from a function which is not the
owner of the memory.

Free should happen from the owner of resources.

glusterd/snapshot: remove quota related options from snap volfile

2016-06-03T06:08:56+00:00

enabling inode-quota on a snapshot volume is unnecessary, because
snapshot is a read-only volume. So we don't need to enforce quota
on a snapshot volume.

This patch will remove the quota related options from snapshot
volfile.

clone/snapshot: Save restored_from_snap for clones

2016-04-25T08:42:46+00:00

Bricks of cloned volumes are lvm bricks mounted in
/run/gluster, which on reboot of the node gets
cleared. Hence, these brick paths need to be recreated
on glusterd restart and the appropriate lvms are
mounted.

snapshot/quota: Copy quota.cksum during snapshot operations

2016-04-22T05:51:08+00:00

A volume having a quota.conf file, should always have
a quota.cksum file too. Based on this above assumption
modifying glusterd_copy_quota_files() to always copy
quota.cksum, if quota.conf is present.

This change will be reflected when a snapshot is created,
restored and cloned.

glusterd: use string comparison for realpath checks in glusterd_is_brickpath_available

2016-02-29T11:55:23+00:00

glusterd_is_brickpath_available () used to call realpath() for checking the
whether the new brick path matches with the existing ones. The problem with this
is if the underlying file system is bad for any one of the existing bricks then
realpath() would fail and we wouldn't allow to create the new brick even if it
should be allowed.

Fix is to use string comparison with having a new field real_path in brickinfo
to store the absolute path
