glusterfsd: allow subdir mount

2017-08-04T05:26:42+00:00

Changes:

1. Take subdir mount option in client (mount.gluster / glusterfsd)
2. Pass the subdir mount to server-handshake (from client-handshake)
3. Handle subdir-mount dir's lookup in server-first-lookup and handle
   all fops resolution accordingly with proper gfid of subdir
4. Change the auth/addr module to handle the multiple subdir entries
   in option, and valid parsing.

How to use the feature:

`# mount -t glusterfs $hostname:/$volname/$subdir /$mount_point`
Or
`# mount -t glusterfs $hostname:/$volname -osubdir_mount=$subdir /$mount_point`

Option can be set like:

`# gluster volume set  auth.allow "/subdir1(192.168.1.*),/(192.168.10.*),/subdir2(192.168.8.*)"`

Updates #175

Fixes quota aux mount failure

2017-05-08T06:15:55+00:00

The aux mount is created on the first limit/remove_limit/list command
and it remains until volume is stopped / deleted / (quota is disabled)
, where we do a lazy unmount. If the process is uncleanly terminated,
then the mount entry remains and we get (Transport disconnected) error
on subsequent attempts to run quota list/limit-usage/remove commands.

Second issue, There is also a risk of inadvertent rm -rf on the
/var/run/gluster causing data loss for the user. Ideally, /var/run is
a temp path for application use and should not cause any data loss to
persistent storage.

Solution:
1) unmount the aux mount after each use.
2) clean stale mount before mounting, if any.

One caveat with doing mount/unmount on each command is that we cannot
use same mount point for both list and limit commands.
The reason for this is that list command needs mount to be accessible
in cli after response from glusterd, So it could be unmounted by a
limit command if executed in parallel (had we used same mount point)
Hence we use separate mount points for list and limit commands.

core: run many bricks within one glusterfsd process

2017-01-31T00:13:58+00:00

This patch adds support for multiple brick translator stacks running
in a single brick server process.  This reduces our per-brick memory usage by
approximately 3x, and our appetite for TCP ports even more.  It also creates
potential to avoid process/thread thrashing, and to improve QoS by scheduling
more carefully across the bricks, but realizing that potential will require
further work.

Multiplexing is controlled by the "cluster.brick-multiplex" global option.  By
default it's off, and bricks are started in separate processes as before.  If
multiplexing is enabled, then *compatible* bricks (mostly those with the same
transport options) will be started in the same process.

features/trash: Create trash directory only when it is enabled

2017-01-20T12:12:20+00:00

Previously trash directory was being created as part of volume
start operation. And also the user/admin could not delete this
directory from volume even if it is not needed. This patch will
fix the same. From now onwards creation and enforcement on trash
directory will come into pictrure only when trash translator is
enabled. Similarly exact same behaviour is reflected on internal-op
directory inside trash directory.

performance/write-behind: guaranteed retry after a short write

2016-05-04T12:01:46+00:00

* Don't mark the request with a fake EIO after a short write.
* retry the remaining buffer at least once before unwinding reply to
  application. This way we capture correct error from backend (ENOSPC,
  EDQUOT etc).

Thanks to "Vijaikumar Mallikarjuna" for the test
script.

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

Next step in eventual deprecation of glusterfs nfs server in favor
of ganesha.nfsd.

Also replace several open-coded strings with constant.

tests: Add mechanism for disabled tests

2016-03-10T07:19:40+00:00

Requirements:
Should be able to skip tests from run-tests.sh run.
Should be granular enough to disable on subset of OSes.

Solution:
Tests can have special comment lines with some comma separated values
within them.

Key names used to determine test status are
G_TESTDEF_TEST_STATUS_CENTOS6
G_TESTDEF_TEST_STATUS_NETBSD7
Some examples:
G_TESTDEF_TEST_STATUS_CENTOS6=BAD_TEST,BUG=123456
G_TESTDEF_TEST_STATUS_NETBSD7=KNOWN_ISSUE,BUG=4444444
G_TESTDEF_TEST_STATUS_CENTOS6=BAD_TEST,BUG=123456;555555
You can change status of test to enabled or delete the line only if all the
bugs are closed or modified or if the patch fixes it.
