features/shard: Regulate memory consumption by individual shards' inode_t objects

2015-10-09T05:17:13+00:00

Shard translator will now maintain an lru list of inodes associated with
individual shards of constant size, and will make sure that at no point the
number of these inodes will exceed the configured limit.
This is to keep the memory consumption by the thousands of shards of every large
file from exploding.

features/shard: Performance improvements in IO path

2015-09-23T05:51:38+00:00

This is patch 1/2 of the performance improvement work
for sharding in the IO path.
What this patch does:
Since the primary use-case where sharding is targeted -
VM store - is a single-writer workload, instead of
performing lookup on the base file everytime to gather the
size and block count from the backend in reads, writes and
truncate, now the size and block count is also cached and
kept up-to-date after every inode write in the inode ctx.

TO-DO:
Make changes in rename, link, unlink, [f]setattr and [f]stat
to keep the relevant iatt members up-to-date in the inode ctx.

features/shard: Fix permission issues

2015-08-30T15:20:21+00:00

This patch does the following:
* reverts commit b467af0e99b39ef708420d3f7f6696b0ca618512
* changes ownership on shards under /.shard to be root:root
* makes readv, writev, [f]truncate, rename, and unlink fops
  to perform operations on files under /.shard with
  frame->root->{uid,gid} as 0.

This would ensure that a [f]setattr on a sharded file
does not need to be called on all the shards associated with it.
