cli/glusterd: improve rebalance fix-layout status reporting

2013-09-19T16:22:36+00:00

Problem:
Currenly the CLI rebalance status command output does not indicate the
'type' of rebalance, i.e. whether a full rebalance or only a fix-layout
was carried out.

Fix: After the rebalance status of all peers is received by the
originator glusterd, alter it to reflect the type of rebalance
before passing it on to the CLI process.

rpc: duplicate request cache for nfs

2013-06-21T17:33:49+00:00

Duplicate request cache provides a mechanism for detecting
duplicate rpc requests from clients. DRC caches replies
and on duplicate requests, sends the cached reply instead of
re-processing the request.

glusterfs: discard (hole punch) support

2013-06-13T21:37:43+00:00

Add support for the DISCARD file operation. Discard punches a hole
in a file in the provided range. Block de-allocation is implemented
via fallocate() (as requested via fuse and passed on to the brick
fs) but a separate fop is created within gluster to emphasize the
fact that discard changes file data (the discarded region is
replaced with zeroes) and must invalidate caches where appropriate.

gluster: add fallocate fop support

2013-06-13T21:37:21+00:00

Implement support for the fallocate file operation. fallocate
allocates blocks for a particular inode such that future writes
to the associated region of the file are guaranteed not to fail
with ENOSPC.

This patch adds fallocate support to the following areas:

	- libglusterfs
	- mount/fuse
	- io-stats
	- performance/md-cache,open-behind
	- quota
	- cluster/afr,dht,stripe
	- rpc/xdr
	- protocol/client,server
	- io-threads
	- marker
	- storage/posix
	- libgfapi

cli: add a command 'gluster pool list [--xml]'

2013-04-26T11:28:06+00:00

* unlike 'gluster peer status', which lists only info about peers,
  this command lists localhost also in the list, so the sorted
  output from all the nodes should match.

* made the output script friendly by keeping it one output per line.
