glusterd: populate brickinfo->real_path conditionally

2016-04-11T18:39:16+00:00

glusterd_brickinfo_new_from_brick () is called from multiple places and one of
them is glusterd_brick_rpc_notify where its very well possible that an
underlying brick's file system has crashed and a disconnect event has been
received. In this case glusterd tries to build the brickinfo from the brickid in
the RPC request, however the same fails as glusterd_brickinfo_new_from_brick ()
fails from realpath.

Fix is to skip populating real_path if its a disconnect event.

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: making detach start fail when brick on hot tier is down

2016-03-03T11:51:14+00:00

Currently detach tier start happens even when a hot brick is down
this might lead to data loss.

This patch prevents the detach tier start from being executed
successfully if a brick in hot tier is down

cluster/tier make cache mode default for tiered volumes

2015-11-17T12:18:17+00:00

The default mode for tiered volumes must be cache. The current
test mode was for engineering and should ordinarily not be used
by customers.

glusterd: brick failed to start

2015-11-16T09:19:58+00:00

brick volfiles are generated in post validate, if
it is running version higher than GLUSTER_3_7_5,
else will be running in syncop.

If the code fall back to syncop, and volume is stopped
then we were returning the operation with out generating
volfiles.

cluster/tier enable CTR on attach tier

2015-10-30T12:21:43+00:00

CTR is currently disabled by default, and must be manually enabled
for tiering to start. This is an overhead on the administrator and
easy to overlook. Enable it automatically when a tier is attached.

tiering/glusterd: keep afr/ec xlators name constant

2015-10-09T04:21:07+00:00

afr uses the translator name for locking purpose,
so it is mandatory to keep afr/ec xlators name constant
across graph change

currently when a tier is attached, afr names are appended
either with hot or cold. ie that breaks the above
mentioned constraint.

glusterd/add-brick: change add-brick implementation to v3 framework

2015-10-07T09:09:36+00:00

add-brick commit first happens on local node and followed by peers.
As part of the commit of local-host glusterd will send the updated
volfiles to the clients connected to the local-host even before the
commit of peers happen. If any of the newly added brick was hosted
by any peer, that brick won't be started when client (connected to
local-host) try to send fops.

By changing to v3 framework we can send post validate ops
after commit operation that helps to send volfile fetch request only
after completing commits on all nodes.
