features/shard: Fix block-count accounting upon truncate to lower size

The way delta_blocks is computed in shard is incorrect, when a file
is truncated to a lower size. The accounting only considers change
in size of the last of the truncated shards.

FIX:

Get the block-count of each shard just before an unlink at posix in
xdata.  Their summation plus the change in size of last shard
(from an actual truncate) is used to compute delta_blocks which is
used in the xattrop for size update.

cluster/ec: honor contention notifications for partially acquired locks

2019-06-03T04:08:06+00:00

EC was ignoring lock contention notifications received while a lock was
being acquired. When a lock is partially acquired (some bricks have
granted the lock but some others not yet) we can receive notifications
from acquired bricks, which should be honored, since we may not receive
more notifications after that.

Since EC was ignoring them, once the lock was acquired, it was not
released until the eager-lock timeout, causing unnecessary delays on
other clients.

This fix takes into consideration the notifications received before
having completed the full lock acquisition. After that, the lock will
be releaed as soon as possible.

glusterd: define dumpops in the xlator_api of glusterd

2019-05-08T13:57:24+00:00

Problem: statedump is not capturing information related to glusterd

Solution: statdump is not capturing glusterd info because
trav->dumpops is null in gf_proc_dump_single_xlator_info ()
where trav is glusterd xlator object. trav->dumpops is null
because we missed to define dumpops in xlator_api of glusterd.
defining dumpops in xlator_api of glusterd fixes the issue.

cluster/ec: fix fd reopen

2019-05-08T13:54:59+00:00

Currently EC tries to reopen fd's that have been opened while a brick
was down. This is done as part of regular write operations, just after
having acquired the locks, and it's sent as a sub-fop of the main write
fop.

There were two problems:

1. The reopen was attempted on all UP bricks, even if a previous lock
didn't succeed. This is incorrect because most probably the open will
fail.

2. If reopen is sent and fails, the error is propagated to the main
operation, causing it to fail when it shouldn't.

To fix this, we only attempt reopens on bricks where the current fop
owns a lock, and we prevent any error to be propagated to the main
fop.

To implement this behaviour an argument used to indicate the minimum
number of required answers has overloaded to also include some flags. To
make the change consistent, it has been necessary to rename the
argument, which means that a lot of files have been changed. However
there are no functional changes.

This change has also uncovered a problem in discard code, which didn't
correctely process requests of small sizes because no real discard fop
was being processed, only a write of 0's on some region. In this case
some fields of the fop remained uninitialized or with incorrect values.
To fix this, a new function has been created to simulate success on a
fop and it's used in the discard case.

Thanks to Pranith for providing a test script that has also detected an
issue in this patch. This patch includes a small modification of this
script to force data to be written into bricks before stopping them.

cluster/afr: Remove local from owners_list on failure of lock-acquisition

2019-04-16T11:29:03+00:00

When eager-lock lock acquisition fails because of say network failures, the
local is not being removed from owners_list, this leads to accumulation of
waiting frames and the application will hang because the waiting frames are
under the assumption that another transaction is in the process of acquiring
lock because owner-list is not empty. Handled this case as well in this patch.
Added asserts to make it easier to find these problems in future.

core: Log level changes do not effect on running client process

2019-04-16T10:59:36+00:00

Problem: commit c34e4161f3cb6539ec83a9020f3d27eb4759a975 set log-level
         per xlator during reconfigure only for a brick process not for
         the client process.

Solution: 1) Change per xlator log-level only if brick_mux is enabled.To make sure
             about brick multiplex introudce a flag brick_mux at ctx->cmd_args.

Note: There are two other changes done with this patch
      1) Ignore client-log-level option to attach a brick with
         already running brick if brick_mux is enabled
      2) Add a log to print pid of the running process to make easier
         debugging

core: Brick is not able to detach successfully in brick_mux environment

2019-04-16T10:55:51+00:00

Problem: In brick_mux environment, while volumes are stopped in a
         loop bricks are not detached successfully. Brick's are not
         detached because xprtrefcnt has not become 0 for detached brick.
         At the time of initiating brick detach process server_notify
         saves xprtrefcnt on detach brick and once counter has become
         0 then server_rpc_notify spawn a server_graph_janitor_threads
         for cleanup brick resources.xprtrefcnt has not become 0 because
         socket framework is not working due to assigning 0 as a fd for socket.
         In commit dc25d2c1eeace91669052e3cecc083896e7329b2
         there was a change in changelog fini to close htime_fd if htime_fd is not
         negative, by default htime_fd is 0 so it close 0 also.

Solution: Initialize htime_fd to -1 after just allocate changelog_priv
          by GF_CALLOC
