snapshot/handshake: store description after strdup

2018-08-20T02:55:43+00:00

problem:
During a handshake, when we import a friend data
snap description variable was just referenced to
dictionary value.

Solution:
snap description should have a separate memory allocated
through gf_strdup

performance/open-behind: don't use anonymous fds for reads by default

2018-08-02T12:13:11+00:00

anonymous fds interfere with working of read-ahead as read-ahead won't
be able to store its cache in fd. Also, as seen in bz 1455872,
anonymous fds also affect performance of large file sequential reads
as the cost of opening fd for each read on brick stack is
significant. So, have a proper fd which enables read-ahead to store
its cache and brick stack to reuse the fd during reads.

With this change test
tests/bugs/snapshot/bug-1167580-set-proper-uid-and-gid-during-nfs-access.t
fails consistently. The failure can also be seen with open-behind
off. bz 1611532 has been filed to track the issue with test. Thanks to
Rafi  for assistance provided in debugging test
failure.

snapshot : remove stale entry

2018-07-12T04:35:58+00:00

        During snap delete after removing brick-path we should remove
        snap-path too i.e. /var/run/gluster/snaps/.

        During snap deactivate also we should remove snap-path.

glusterd/snapshot : fix the compare snap logic

2018-02-10T12:40:14+00:00

In one of the case in commit cb0339f there's one particular case where
after removing the old snap it wasn't writing the new snap version and
this resulted into one of the test to fail spuriously.

snapshot : snapshot creation failed after brick reset/replace

2017-11-28T07:27:29+00:00

Problem : snapshot creation was failing after brick reset/replace

Fix : changed code to set mount_dir value in rsp_dict during prerequisites
      phase i.e glusterd_brick_op_prerequisites call and removed form prevalidate
      phase.

snapshot: Issue with other processes accessing the mounted brick

2017-10-23T10:05:02+00:00

Added code for unmount of activated snapshot brick during snapshot
deactivation process which make sense as mount point for deactivated
bricks should not exist.

Removed code for mounting newly created snapshot, as newly created
snapshots should not mount until it is activated.

Added code for mount point creation and snapshot mount during snapshot
activation.

Added validation during glusterd init for mounting only those snapshot
whose status is either STARTED or RESTORED.

During snapshot restore, mount point for stopped snap should exist as
it is required to set extended attribute.

During handshake, after getting updates from friend mount point for
activated snapshot should exist and should not for deactivated
snapshot.

While getting snap status we should show relevent information for
deactivated snapshots, after this pathch 'gluster snap status' command
will show output like-

Snap Name : snap1
Snap UUID : snap-uuid

	Brick Path        :   server1:/run/gluster/snaps/snap-vol-name/brick
	Volume Group      :   N/A (Deactivated Snapshot)
	Brick Running     :   No
	Brick PID         :   N/A
	Data Percentage   :   N/A
	LV Size           :   N/A

glusterd: Gluster should keep PID file in correct location

2017-08-11T07:36:41+00:00

Currently Gluster keeps process pid information of all the daemons
and brick processes in Gluster configuration file directory
(ie., /var/lib/glusterd/*).

These pid files should be seperate from configuration files.
Deletion of the configuration file directory might result into serious problems.
Also, /var/run/gluster is the default placeholder directory for pid files.

So, with this fix Gluster will keep all process pid information of all
processes in /var/run/gluster/* directory.
