shard: fix unused variable warnings/errors

2016-08-29T15:14:46+00:00

http://review.gluster.org/14085 fixes a/the "leak" - via the
generated rpc/xdr headers - of pragmas that mask these warnings.

However 14085 won't pass the smoke test until all the warnings are
fixed.

build: correctly format some (s)size_t messages

2016-07-17T13:36:58+00:00

On 32-bit builds the are are warnings like these:

    posix.c:6438: warning: format '%ld' expects type 'long int', but argument 11 has type 'ssize_t'

Instead of using "%l" for (signed) size_t variables, "%z" should be
used.

core, shard: Make shards inherit main file's O_DIRECT flag if present

2016-06-07T07:19:26+00:00

If the application opens a file with O_DIRECT, the shards'
anon fds would also need to inherit the flag. Towards this,
shard xl would be passing the odirect flag in the @flags parameter
to the WRITEV fop. This will be used in anon fd resolution
and subsequent opening by posix xl.

features/shard: Don't modify readv size

2016-06-06T15:12:55+00:00

For o-direct reads application sends aligned size which needs to be
sent as is, otherwise o-direct writes where the file-size is not
aligned fails.

Revert "features/shard: Make o-direct writes work with sharding"

2016-05-17T11:01:39+00:00

This reverts commit c272c71391cea9db817f4e7e38cfc25a7cff8bd5.

This is for two reasons:
1) It introduces high fop latencies
2) Even with the patch, there is no true odirect behavior since the
   workaround in the patch doesn't reduce the caching done in kernel's
   page cache as far as writes on anon fds associated with individual
   shards is concerned.

features/shard: Make o-direct writes work with sharding

2016-04-11T19:48:53+00:00

With files opened with o-direct, the expectation is that
the IO performed on the fds is byte aligned wrt the sector size
of the underlying device. With files getting sharded, a single
write from the application could be broken into more than one write
falling on different shards which _might_ cause the original byte alignment
property to be lost. To get around this, shard translator will send fsync
on odirect writes to emulate o-direct-like behavior in the backend.
