nfs/nlm: procedures for PC clients

2012-05-18T12:53:10+00:00

*  This change introduces four NLMv4 procedures:

   NM_LOCK, SHARE, UNSHARE and FREE_ALL.

   These are used by PC clients (windows/dos) to control access
   to files.

   1. NM_LOCK: this lock is not monitored by statd.

   2. SHARE: A share reservation is a lock on the whole file
      that is taken whenever a file is opened on windows clients.
      This has ACCESS (N, R, W, RW) and DENY MODE (N, R, W, RW).
        ACCESS:    mode of access requested by the client;
        DENY MODE: what the requesting client wants to
                   deny other clients.

   3. UNSHARE: remove a share reservation obtained by SHARE.
      Called while closing a file.

   4. FREE_ALL: remove all share reservations and locks,
      both monitored and unmonitored, of the calling client.

*  lock and nm_lock use a common function with only
   a flag conveying whether or not to monitor a lock.

*  NOTES:
   1. SHARE reservations are not STACK_WIND'd to subsequent xlators.
      These are maintained in-memory in the nfs xlator.

   2. Consequently, for SHARE reservations to work effectively,
      all PC clients  *must* mount from the same gNfs server.
      Not doing so will result in different servers maintaining
      separate SHARE reservations which will not be enforced
      for obvious reasons.

rebalance: handshake_event_notify to make fsd talk to glusterd

2012-04-25T11:05:35+00:00

Event_notify can be used by others to communicate with glusterd.
A cbk event is also added for future use.

req has a op, and dict.
rsp has op_ret, op_errno, and dict.

With this, rebalance process can update the status before
exiting.

glusterd/remove-brick: Replace ABORT with STOP

2012-04-13T07:46:59+00:00

Remove-brick stop now invokes rebalance stop. This leads
to a graceful stop of decommissioning.
The volfile is also updated (removal of decommission)

nfs/nlm: dummy actor for FREE_ALL procedure

2012-04-05T12:10:40+00:00

NLM4_FREE_ALL rpc procedure has been provided nlm's
null procedure as actor to facilitate windows Nfs mounts.

NOTE: windows Nfs needs several other NLM procedures to work.
As a result, this patch only makes it possible to do a working
mount of a volume with "nolock" option in windows.
*Windows mount WITHOUT "nolock" option does NOT work as expected*

cli,glusterd: more volume status improvements

2012-03-29T14:47:53+00:00

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.

core: adding extra data for fops

2012-03-22T23:40:27+00:00

with this change, the xlator APIs will have a dictionary as extra
argument, which is passed between all the layers. This can be
utilized for overloading in some of the operations.

cli, glusterd, nfs: "volume status|profile|top" for nfs servers

2012-03-14T09:27:42+00:00

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  {start|info|stop} [nfs]
 #gluster volume top  {[open|read|write|opendir|readdir [nfs]]
               |[read-perf|write-perf [nfs|{bs  count }]]}
               [brick ] [list-cnt ]
 #gluster volume status [all |  [nfs|]]
          [detail|clients|mem|inode|fd|callpool]
