nfs: correct phrasing of nfs-mount-udp option

2012-12-27T08:06:13+00:00

`gluster volume set help` shows the following typo for the nfs.mount-udp
option:

Option: nfs.mount-udp
Default Value: (null)
Description: set the option to 'on' to enable mountd on UDP. Needed by
Solaris NFS clients if NLM support isneeded

Also, AIX NFS-clients seem to need this option, hence rephrasing the
description to be more helpful.

nfs: do lookup on getattr after brick-status change

2012-10-19T14:16:33+00:00

By doing a lookup, we get a chance to do all of the self-heal checks that
would occur if we were using native protocol, and return proper status if
the self-heal fails.  Best of all, we don't need to misrepresent times.

libglusterfs,mount/fuse: implement gidcache mechanism in fuse-bridge

2012-07-17T15:11:48+00:00

This change genericizes the cache mechanism implemented in commit
8efd2845 into libglusterfs/src/gidcache.[ch] and adds fuse-bridge as
a client. The cache mechanism is fundamentally equivalent, with some
minor changes:

  - Change cache key from uid_t to uint64_t.
  - Modify the cache add logic to locate and use an entry with a
    matching ID, should it already exist. This addresses a bug in
    the existing mechanism where an expired entry supercedes a newly
    added entry in lookup, causing repeated adds and flushing of a
    cache bucket.

The fuse group cache is disabled by default. It can be enabled via
the 'gid-timeout' fuse-bridge translator option and accompanying
mount option (i.e., '-o gid-timeout=1' for a 1s entry timeout).

nfs/nlm: procedures for PC clients

2012-05-17T09:12:49+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.
