quota: start aux mount from glusterd with inet address

2016-01-22T11:27:14+00:00

This is a backport of http://review.gluster.org/#/c/13255

With below patches, quota aux mount now
uses unix domain socket to connect to
glusterd
http://review.gluster.org/#/c/12645/
http://review.gluster.org/#/c/12819/

When USS is enabled, snapd protocol client tries to
connect to glusterd with inet and fails,
because remote-host option by client process
is set to UDS file

This patch starts the aux client process from glusterd
with inet address

cli : 'gluster volume help' output sorted alphabetically

2015-11-02T10:03:28+00:00

'gluster volume help' output is not sorted alphabetically.
This makes little harder for the user to search or get to know of
few gluster volume commands usage just from gluster cli.

glusterd/shared_storage: Provide a volume set option to create and mount the shared storage

2015-06-05T09:20:26+00:00

     Backport of http://review.gluster.org/#/c/10793/

Introducing a global volume set option(cluster.enable-shared-storage)
which helps create and set-up the shared storage meta volume.

gluster volume set all cluster.enable-shared-storage enable

On enabling this option, the system analyzes the number of peers
in the cluster, which are currently connected, and chooses three
such peers(including the node the command is issued from). From these
peers a volume(gluster_shared_storage) is created. Depending on the
number of peers available the volume is either a replica 3
volume(if there are 3 connected peers),  or a replica 2 volume(if there
are 2 connected peers). "/var/run/gluster/ss_brick" serves as the
brick path on each node for the shared storage volume. We also mount
the shared storage at "/var/run/gluster/shared_storage" on all the nodes
in the cluster as part of enabling this option. If there is only one node
in the cluster,  or only one node is up then the command will fail

Once the volume is created, and mounted the maintainance of the
volume like adding-bricks, removing bricks etc., is expected to
be the onus of the user.

On disabling the option, we provide the user a warning, and on
affirmation from the user we stop the shared storage volume, and unmount
it from all the nodes in the cluster.

gluster volume set all cluster.enable-shared-storage disable

quota: support for inode quota in quota.conf

2015-05-08T06:54:33+00:00

Currently when quota limit is set, corresponding gfid
is set in quota.conf. This patch supports storing
inode-quota limits in quota.conf and also stores
additional byte for each gfid to differentiate
between usage quota limit and inode quota limit.

NFS-Ganesha: Handling CLI commands when NFS-Ganesha keys are set

2015-05-03T11:34:42+00:00

When ganesha.enable is set to on and features.ganesha is
enabled, there are a few behaviour changes that should
be seen in other volume operations.

1. ganesha.enable can be set to 'on' only
when features.ganesha is set to 'enable'

2.When gluster vol is started, and if ganesha.enable
key was set to 'on', it should automatically export the volume
via NFS-Ganesha.

3.When ganesha.enable is set to 'on', and a volume
is stopped, that volume should be unexported via NFS-Ganesha.

4. gluster vol reset 
If ganesha.enable was set to on, then unexport the
volume via NFS-Ganesha.

5. gluster vol reset all
If features.ganesha is set to enable, as part
of reset all, set it to disable. This translates
to teardown cluster.

All the above problems are fixed by checking the global key
and value, depending on the value, specific functions are called.
And also, functions related to global commands
are moved to cli-cmd-global.c

Commit phase of features.ganesha enable/disable
runs the ganesha-ha.sh setup/teardown respectively.
Before the script begins, it is important that the
NFS-Ganesha service starts on all the HA nodes.
Having the start service commands in the
commit phase could lead to problems.
Moving the pre-requisite service start
commands to the 'stage' phase.

glusterd: Move brick order check from cli to glusterd.

2014-09-24T12:29:43+00:00

Previously the brick order check for replicate volumes on volume
create and add-brick was done by the cli. This check would fail
when a hostname wasn't resolvable and would question the user
if it was ok to continue. If the user continued, glusterd would
fail the command again as the hostname wouldn't be resolvable.
This was unnecessary.

This change, moves the check from cli into glusterd. The check
is now performed during staging of volume create after the
bricks have been resolved. This prevents the above condition
from occurring.

As a result of this change, the user will no longer be
questioned and given an option to continue the operation
when a bad brick order is given or the brick order check
fails. In such a case, the user can use 'force' to bypass
the check and allow the command to succeed.
