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.

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]

mempool: adjustments in pool sizes

2012-02-22T12:23:48+00:00

* while creating 'rpc_clnt', the caller knows what would be the ideal
  load on it, so an extra argument to set some pool sizes

* while creating 'rpcsvc', the caller knows what would be the ideal
  load of it, so an extra argument to set request pool size

* cli memory footprint is reduced
