glusterd-ganesha : copy ganesha export configuration files during reboot

2016-05-18T13:55:39+00:00

glusterd creates export conf file for ganesha using hook script during
volume start and ganesha_manage_export() for volume set command. But this
routine is not added in glusterd restart scenario.
Consider the following case, in a three node cluster a volume got exported
via ganesha while one of the node is offline(glusterd is not running).
When the node comes back online, that volume is not exported on that node
due to the above mentioned issue.
Also I have removed unused variables from glusterd_handle_ganesha_op()
For this patch to work pcs cluster should running on that be node.

quota/glusterd: enhance quota enable and disable process

2016-04-29T10:11:35+00:00

Previously quota crawl was done from the single mount point,
this is very slow process if there are huge number of files exists
in the volume

This RFE will now spawn crawl process for each brick in the
volume, and  files are looked in parallel independently for each
brick. This improves the speed of crawling process for
entire files-system

This patch also fixes below problem
* Previously, mountdir was created under '/tmp'.
  If someone tries to cleanup '/tmp'/ directory
  then it is very dangerous that we loose volume data
  So create a mount point under /var/run/gluster/tmp
  instead

* Previously, file-system crawl is performed from all the nodes,
  which is a redundant operation and performance will degrade
  The problem is fixed with this patch

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

glusterd: set decommission_is_in_progress flag for inprogress remove-brick op on glusterd restart

2016-02-23T05:42:31+00:00

While remove brick is in progress, if glusterd is restarted since decommission
flag is not persisted in the store the same value is not retained back resulting
in glusterd not blocking remove brick commit when rebalance is already in
progress.

Tier: "tier start force" command implementation

2015-12-23T00:24:11+00:00

The start command doesnt restart the tier deamon if the deamon
is running at one node. hence to bring up the tierd on the nodes
where the deamon is down, the force command is implemented.
It skips the check for tierd running.
