glusterd/shared_storage: Use /var/lib/glusterd/ss_brick as shared storage's brick

2015-07-07T05:55:48+00:00

     Backport of http://review.gluster.org/#/c/11533/

The brick path we use to create shared storage is
/var/run/gluster/ss_brick.

The problem with using this brick path is /var/run/gluster
is a tmpfs and all the brick/shared storage data will be wiped
off when the node restarts. Hence using /var/lib/glusterd/ss_brick
as the brick path for shared storage volume as this brick and
the shared storage volume is internally created by us (albeit on
user's request), and contains only internal state data and no user data.

While creating/deleting shared storage volume, add/remove the shared storage
entry from /etc/fstab, so as to ensure availability of the shared storage,
even after a node reboot

NFS-Ganesha: Automatically export vol that was exported before vol restart

2015-06-18T17:24:42+00:00

Consider a volume that is exported via NFS-Ganesha. Stopping this
volume will automatically unexport the volume. Starting this volume
should automatically export it. Although the logic was already there,
there was a bug in it. Fixing the same by introducing a hook script.

Also with the new CLI options, the hook script S31ganesha-set.sh
is no longer required. Hence, removing the same.
Adding a comment to tell the user that one of the CLI
commands will take a few minutes to complete.

This is a backport of the patch merged on master,

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

Hook scripts should exit with correct exit status.

2014-08-31T18:05:04+00:00

When volume set options other than nfs-ganesha.host and nfs-ganesha.enable
are executed, the hook script S31ganesha-set.sh should exit with
exit status 0. The present behaviour results in an error message in
one of the logs that could be  misleading.

Similarly, hook script S30samba-set.sh should exit with
exit status 0 if samba is not installed. Fixing the issue
with a minor change in the script.

build: make GLUSTERD_WORKDIR rely on localstatedir

2014-08-07T08:17:29+00:00

- Break-way from '/var/lib/glusterd' hard-coded previously,
  instead rely on 'configure' value from 'localstatedir'
- Provide 's/lib/db' as default working directory for gluster
  management daemon for BSD and Darwin based installations
- loff_t is really off_t on Darwin
- fix-off the warnings generated by clang on FreeBSD/Darwin
- Now 'tests/*' use GLUSTERD_WORKDIR a common variable for all
  platforms.
- Define proper environment for running tests, define correct PATH
  and LD_LIBRARY_PATH when running tests, so that the desired version
  of glusterfs is used, regardless where it is installed.

gluster vol set nfs-ganesha.enable off fails to unexport volume.

2014-08-05T10:33:40+00:00

 Due to a parameter type change in upstream nfs-ganesha
( v2.1 and above ), gluster vol set  nfs-ganesha.enable
 off doesn't unexport the volume in question if it was already
exported.
A minor change in the hook script would result in the
expected behaviour.
