glusterd-volgen.c: remove BD xlator from the graph

2019-06-18T12:09:09+00:00

The BD xlator was removed some time ago. Remove it from the graph.
We can also remove the caps settings - only the BD xlator
was using it.

Lastly, remove the caps (which only BD was using) and the document
describing the translator.

glusterd/tier: gluster upgrade broken because of tier

2019-06-03T13:31:54+00:00

Problem: While tier code was removed, the is_tier_enabled
related to tier wasn't handled for upgrade.
As this option was missing in the info file, the checksum
mismatch issue happens during upgrade.
This results in the peer rejections happening.

Fix: use the op_version check and note down the is_tier_enabled
always. This way it will be dummy key, but the future upgrades
will work fine.

NOTE: Just having the key from 3.10 to 7 will cause issues when
upgraded from 5 to 8 or any such upgrade which skips the version
where we handle it.

glusterd/tier: remove tier related code from glusterd

2019-05-27T07:50:24+00:00

The handler functions are pointed to dummy functions.
The switch case handling for tier also have been moved to
point default case to avoid issues, if reintroduced.

The tier changes in DHT still remain as such.

glusterd/store: store all key-values in one shot

2019-05-08T06:46:24+00:00

Instead of saving each key-value separately, which is slow (
especially as we fflush() after each!), store them all as one
string and write all together.

Implements https://github.com/gluster/glusterfs/issues/629

glusterd: Fix coverity defects & put coverity annotations

2019-05-02T08:06:06+00:00

Along with fixing few defect, put the required annotations for the defects which
are marked ignore/false positive/intentional as per the coverity defect sheet.
This should avoid the per component graph showing many defects as open in the
coverity glusterfs web page.

glusterd: get-state command should not fail if any brick is gone bad

2019-02-05T14:40:25+00:00

Problem: get-state command will error out, if any of the underlying
brick(s) of volume(s) in the cluster go bad.

It is expected that get-state command should not error out, but
should generate an output successfully.

Solution: In glusterd_get_state(), a statfs call is made on the
brick path for every bricks of the volumes to calculate the total
and free memory available. If any of statfs call fails on any
brick, we should not error out and should report total memory and free
memory of that brick as 0.

This patch also handles a statfs failure scenario in
glusterd_store_retrieve_bricks().

glusterd: manage upgrade to current master

2019-02-04T03:47:15+00:00

Scenarios tested:

* Upgrade the node when there are stripe / tiering and regular
type of volumes are present.
  - All volumes are started fine (as the change was not on brick volfile)
  - For tier, the functionality may not even work, as changetimerecorder
    is not present.
  - 'gluster volume info' properly shows as 'NOT SUPPORTED' for stripe and
    tier type of volume.

* Upgrade in a rolling upgrade scenario, where an old version is
able to connect to higher master.
  - on a normal volume, if the volfile-server was new, the newer client
    volfiles needed to have utime xlator conditionally.
  - with this one change, all other changes seem to work fine.

libglusterfs: Move devel headers under glusterfs directory

2018-12-05T21:47:04+00:00

libglusterfs devel package headers are referenced in code using
include semantics for a program, this while it works can be better
especially when dealing with out of tree xlator builds or in
general out of tree devel package usage.

Towards this, the following changes are done,
- moved all devel headers under a glusterfs directory
- Included these headers using system header notation <> in all
code outside of libglusterfs
- Included these headers using own program notation "" within
libglusterfs

This change although big, is just moving around the headers and
making it correct when including these headers from other sources.

This helps us correctly include libglusterfs includes without
namespace conflicts.
