glusterd, rda: If parallel readdir is enabled, split the cache limit

2017-01-23T08:00:24+00:00

With patch http://review.gluster.org/#/c/16072/ readdir-ahead can be
loaded as a child of dht. i.e. there can be more than one instance
of readdir-ahead in client process. In this case the rda-cache-size
should be split among all the readdir-ahead instances. Also the
value of rda-request-size is considered as the minimum cache size
of any readdir-ahead instance.

glusterd: Change the volfile to have readdir-ahead as a child

2017-01-18T04:05:11+00:00

          of dht

As mentioned in feature page http://review.gluster.org/#/c/16090/
readdir-ahead will be optionally placed below dht.

There are two options:
1. performance.readdir-ahead
2. performance.parallel-readdir

If only option is enabled, then readdir ahead is placed at its
original place as an ancestor of dht. If both the options 1 and 2
are enabled then readdir ahead is placed as a child of dht.

Also changes have been made to retain the rebalance, quotad,
snapd vol files to remain unchanged.

tier : Tier as a service

2017-01-17T04:49:47+00:00

tierd is implemented by separating from rebalance process.

The commands affected:

1) Attach tier will trigger this process instead of old one
2) tier start and tier start force will also trigger this process.
3) volume status [tier] will show tier daemon as a process instead
of task and normal tier status and tier detach status works.
4) tier stop implemented.
5) detach tier implemented separately along with new detach tier
status
6) volume tier volname status will work using the changes.
7) volume set works

This patch has separated the tier translator from the legacy
DHT rebalance code. It now sends the RPCs from the CLI
to glusterd separate to the DHT rebalance code.
The daemon is now a service, similar to the snapshot daemon,
and can be viewed using the volume status command.

The code for the validation and commit phase are the same
as the earlier tier validation code in DHT rebalance.

The “brickop” phase has been changed so that the status
command can use this framework.

The service management framework is now used.
DHT rebalance does not use this framework.

This service framework takes care of :

*) spawning the daemon, killing it and other such processes.
*) volume set options , which are written on the volfile.
*) restart and reconfigure functions. Restart is to restart
the daemon at two points
        1)after gluster goes down and comes up.
        2) to stop detach tier.
*) reconfigure is used to make immediate volfile changes.
By doing this, we don’t restart the daemon.
it has the code to rewrite the volfile for topological
changes too (which comes into place during add and remove brick).

With this patch the log, pid, and volfile are separated
and put into respective directories.

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

2016-05-19T16:40:04+00:00

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.
