cli/glusterd: add/remove brick fixes for arbiter volumes

2016-05-24T08:35:57+00:00

Backport of: http://review.gluster.org/14126

1.Provide a command to convert replica 2 volumes to arbiter volumes.
Existing self-heal logic will automatically heal the file hierarchy into
the arbiter brick, the progress of which can be monitored using the
heal info command.

Syntax: gluster volume add-brick  replica 3 arbiter 1


2. Add checks when removing bricks from arbiter volumes:
- When converting from arbiter to replica 2 volume, allow only arbiter
  brick to be removed.
- When converting from arbiter to plain distribute volume, allow only if
  arbiter is one of the bricks that is removed.

3. Some clean-up:
- Use GD_MSG_DICT_GET_SUCCESS instead of GD_MSG_DICT_GET_FAILED to
log messages that are not failures.
- Remove unused variable `brick_list`
- Move 'brickinfo->group' related functions to glusted-utils.

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 / afr : Enable auto heal when replica count increases

2016-03-21T17:51:00+00:00

In replicate volumes, when a brick is added to a replicate
group, heal to the new brick should be triggered.
Also, the new brick should not be considered as source for
healing till it is up to date.

Previously, extended attributes had to be set manually on
the bricks for this to happen. This patch is part 1 patch
to automate this process.

tier/shd: make shd commands compatible with tiering

2015-10-12T11:57:06+00:00

tiering volfiles may contain afr and disperse together
or multiple time based on configuration. And the
informations for those configurations are stored in
tier_info. So most of the volgen code generation
need to be changed to make compatible with it.

quota : volume-reset shouldn't remove quota-deem-statfs

2015-08-07T12:58:10+00:00

Volume-reset shouldn't remove quota-deem-statfs, unless
explicitly specified, when quota is enabled.

1) glusterd_op_stage_reset_volume ()
   'gluster volume set/reset ' features.quota/
   features.inode-quota' should not be allowed as it is deprecated.
   Setting and resetting quota/inode-quota features should be allowed
   only through 'gluster volume quota  enable/disable'.

2) glusterd_enable_default_options ()
   Option 'features.quota-deem-statfs' should not be turned off
   with 'gluster volume reset ', since quota features
   can be set/reset only with 'gluster volume quota 
   enable/disable'.

But, 'gluster volume set features.quota-deem-statfs'
can be turned on/off when quota is enabled.

glusterd: Stop/restart/notify to daemons(svcs) during reset/set on a volume

2015-08-07T06:22:53+00:00

problem : Reset/set commands were not working properly. reset command returns
success but it not sending notification to svcs if corresponding graph modified.

Fix: Whenever reset/set command issued, generate the temp graph and compare
with original graph and do the fallowing actions
1.) If both graph are identical nothing to do with svcs.
2.) If any changes in graph topology restart/stop service by calling
svc manager.
3)  If changes in options send notify signal by calling glusterd_fetchspec_notify.

SSL improvements: ECDH, DH, CRL, and accessible options

2015-08-05T11:51:43+00:00

- Introduce ssl.dh-param option to specify a file containinf DH parameters.
  If it is provided, EDH ciphers are available.

- Introduce ssl.ec-curve option to specify an elliptic curve name. If
  unspecified, ECDH ciphers are available using the prime256v1 curve.

- Introduce ssl.crl-path option to specify the directory where the
  CRL hash file can be found. Setting to NULL disable CRL checking,
  just like the default.

- Make all ssl.* options accessible through gluster volume set.

- In default cipher list, exclude weak ciphers instead of listing
  the strong ones.

- Enforce server cipher preference.

- introduce RPC_SET_OPT macro to factor repetitive code in glusterd-volgen.c

- Add ssl-ciphers.t test to check all the features touched by this change.
