There are primarily three lists that are part of glusterd process,
that are concurrently accessed. Namely, priv->volumes, priv->peers
and volinfo->bricks_list.
Big-lock approach
-----------------
WHAT IS IT?
Big lock is a coarse-grained lock which protects all three
lists, mentioned above, from racy access.
HOW DOES IT WORK?
At any given point in time, glusterd's thread(s) are in execution
_iff_ there is a preceding, inbound network event. Of course, the
sigwaiter thread and timer thread are exceptions.
A network event is an external trigger to glusterd, via the epoll
thread, in the form of POLLIN and POLLERR.
As long as we take the big-lock at all such entry points and yield
it when we are done, we are guaranteed that all the network events,
accessing the global lists, are serialised.
This amounts to holding the big lock at
- all the handlers of all the actors in glusterd. (POLLIN)
- all the cbks in glusterd. (POLLIN)
- rpc_notify (DISCONNECT event), if we access/modify
one of the three lists. (POLLERR)
In the case of synctask'ized volume operations, we must remember that,
if we held the big lock for the entire duration of the handler,
we may block other non-synctask rpc actors from executing.
For eg, volume-start would block in PMAP SIGNIN, if done incorrectly.
To prevent this, we need to yield the big lock, when we yield the
synctask, and reacquire on waking up of the synctask.

This patch makes log changes mostly in the op state machine as also
in volume stop codepath of glusterd.
Changes made:
* Moved log level from INFO to DEBUG, of log messages on the various
state transitions within a transaction.
For example, messages of the following kind:
a. "Sent op req to <n> peers"
b. "Received LOCK from uuid: <peer-uuid>", etc.
* Changed some of the log messages to give as much information as
available in case of failure.
* Added logs to identify on which machine lock/stage/commit failed.
* Quite a few s/THIS/this changes.
Also, with this change, log changes in all other volume ops
should (hopefully) boil down to modifying the respective logs in
handler, stage and commit (and brick ops in some cases).

This command is necessary when the local disk/filesystem containing a brick
is unexpectedly lost and then recreated. Since 961bc80c, trying to start
the brick will fail because the trusted.glusterfs.volume-id xattr is
missing, and if we can't start it then we can't replace-brick or self-heal
so we're stuck in a permanently degraded state. This command provides a
way to label the empty brick with the proper volume ID so that further
repair actions become possible.

PROBLEM:
In the existing implementation, the success/failure of
execution of a command is decided (and logged) in glusterd
handler functions. Strictly speaking, the logging mechanism
must take into account what course the command takes within
the state machine before concluding whether it succeeded or
failed.
FIX:
This patch attempts to fix the above issue for vol commands.
The format of the log message is as follows:
for failure:
<command string> : FAILED : <cause of failure>
for success:
<command string> : SUCCESS
APPROACH (in a nutshell):
* The command string is packed into dict at cli and sent to
glusterd.
* glusterd logs the command status just before doing a
"submit_reply", which is called (either directly or
indirectly via a call to glusterd_op_cli_send_response)
at 2 places for every vol command:
i. in handler functions, and
ii. in glusterd_op_txn_complete
In short, the failure of a command in the handler implies the
command has indeed failed. However, its success in the handler
does NOT necessarily mean the command succeeded/will succeed.

All calls to dict_allocate_and_serialize() pass the address of a 32-bit
type, but must cast it to the 64-bit pointer type (size_t *).
This happens to work on LE machines, but even if it's apparently benign,
it's still a bug. On BE machines it is not benign.
GF_PROTOCOL_DICT_SERIALIZE() hacks around it by creating a size_t temp
var, but that's, well, a hack, IMO when you consider that all the callers
are actually passing &<u_int>; the param should just be a u_int * and
eliminate the buggy casts and the temp var in the macro.
Nobody apparently uses the Fedora/EPEL PPC RPMs, but they might. People
are trying to build gluster.org bits on SPARC and tripping over this.

A commonly faced problem among glusterfs users is: after a fresh
installation of glusterfs in a virtual machine, the VM image is
cloned to make multiple instances of the server. This breaks
glusterd because right after glusterfs installation on the first
boot glusterd would have created the node UUID and this gets
inherited into the clone. The result is wierd behavior at the time
of peer probe where glusterd does not (yet) deal with UUID
collisions in a user friendly way.
This patch is for the 'prevention' of the issue. The approach here
is to avoid generating a UUID on the first start of glusterd, but
instead generate a node UUID only when a node UUID is found to be
necessary. This naturally avoids the creation of node UUID on first
boot and prevents the issue to a large extent.
This issue also needs a 'cure' patch, which gives more meaningful
error messages to the user and provides CLI to recover from the
situations (gluster peer reset?)

Presently glusterd only returns an errno to cli for peer probe command. This
patch allows glusterd to return an errstr as well to cli. An op_errstr member
has been added to gf1_cli_probe_rsp and gd1_mgmt_probe_rsp structs to allow
this.
In case of an error, cli will display the errstr if it was set. If errstr is not
set cli will display the error message based on errno.
Also, to allow for return of errstr in cases such as handshake failure, an
errstr member has been added to the glusterd_peerctx_t struct.

The major changes are,
* "volume status" now supports getting details of the self-heal daemon processes
for replica volumes. A new cli options "shd", similar to "nfs", has been
introduced for this. "detail", "fd" and "clients" status ops are not supported
for self-heal daemons.
* The default/normal ouput of "volume status" has been enhanced to contain
information about nfs-server and self-heal daemon processes as well. Some tweaks
have been done to the cli output to show appropriate output.
Also, changes have been done to rebalance/remove-brick status, so that hostnames
are displayed instead of uuids.

Enables usage of volume monitoring operations "volume status", "volume top" and
"volume profile" for nfs servers. These operations can be performed on
nfs-servers by passing "nfs" as an option in cli. The output is similar to the
normal brick outputs for these commands.
The new syntaxes for the changed commands are as below,
#gluster volume profile <VOLNAME> {start|info|stop} [nfs]
#gluster volume top <VOLNAME> {[open|read|write|opendir|readdir [nfs]]
|[read-perf|write-perf [nfs|{bs <size> count <count>}]]}
[brick <brick>] [list-cnt <count>]
#gluster volume status [all | <VOLNAME> [nfs|<BRICK>]]

Also, peerinfo is added to peers list synchoronous with the request triggering
it. This ensures that atmost one request sees that the peer (in question) is
not in peers list. Earlier, 'concurrent' handle_friend_update requests would
see that a particular peer is not in the peers list yet, as the addition of the
'peer' into the list happened asynchronously, on the 'connect' event of the
'peer'.

rebalance will not use any maintainance clients. It is replaced by syncops,

encounterd.

Rebalance state is saved in the vol file, for restart-ability.

This patch enables gluster cli to output data in xml format. XML output can be
obtained by passing "--xml" as an argument.
A new "volume list" command, which lists the volumes present in a cluster, has
been added. This can be used for obtaining a quick list of volumes.
Several commands, including "volume top", "volume profile", "volume status" and
"volume info", "volume list", have custom XML output routines. Other commands
use either one of the 2 generic output routines, cli_xml_output_str() &
cli_xml_output_dict().
NOTE: When using "all" for "volume status" and "volume info" the XML output will
have multiple roots.

Changes:
1. Add a new 'volume statedump' command, that performs statedumps of
all the bricks in the volume and saves them in a specified location.
2. Add new server option 'server.statedump-path'.
3. Remove multiple function definitions in glusterd.h
Statedump Information:
The 'volume statedump' command performs statedumps on all the bricks in
a given volume. The syntax of the command is,
gluster volume statedump <VOLNAME> [type]......
Types include,
* all
* mem
* iobuf
* callpool
* priv
* fd
* inode
Defaults to 'all' when no type is specified.
The statedump files are created by default in /tmp directory of the
server on which the bricks are present.
This path can be changed by setting the 'server.statedump-path' option.
The statedump files will be named as,
<brick-name>.<pid of brick process>.dump
