glusterfsd: Use dynamic volfile buffer

2013-07-23T07:26:36+00:00

Glusterfsd used a fixed buffer to store volfiles fetched via getspec.
This caused problems with large volfiles. Changining this to a dynamic
buffer allows large volfiles to be loaded in memory.

fuse: auxiliary gfid mount support

2013-07-19T08:14:08+00:00

* files can be accessed directly through their gfid and not just
  through their paths. For eg., if the gfid of a file is
  f3142503-c75e-45b1-b92a-463cf4c01f99, that file can be accessed
  using /.gfid/f3142503-c75e-45b1-b92a-463cf4c01f99

  .gfid is a virtual directory used to seperate out the namespace
  for accessing files through gfid. This way, we do not conflict with
  filenames which can be qualified as uuids.

* A new file/directory/symlink can be created with a pre-specified
  gfid. A setxattr done on parent directory with fuse_auxgfid_newfile_args_t
  initialized with appropriate fields as value to key "glusterfs.gfid.newfile"
  results in the entry /bname whose gfid is set to args.gfid. The
  contents of the structure should be in network byte order.

  struct auxfuse_symlink_in {
        char     linkpath[]; /* linkpath is a null terminated string */
  } __attribute__ ((__packed__));

  struct auxfuse_mknod_in {
        unsigned int   mode;
        unsigned int   rdev;
        unsigned int   umask;
  } __attribute__ ((__packed__));

  struct auxfuse_mkdir_in {
        unsigned int   mode;
        unsigned int   umask;
  } __attribute__ ((__packed__));

  typedef struct {
        unsigned int  uid;
        unsigned int  gid;
        char          gfid[UUID_CANONICAL_FORM_LEN + 1]; /* a null terminated gfid string
                                                      * in canonical form.
                                                      */
        unsigned int  st_mode;
        char          bname[];     /* bname is a null terminated string */

        union {
                struct auxfuse_mkdir_in   mkdir;
                struct auxfuse_mknod_in   mknod;
                struct auxfuse_symlink_in symlink;
        } __attribute__ ((__packed__)) args;
  } __attribute__ ((__packed__)) fuse_auxgfid_newfile_args_t;

  An initial consumer of this feature would be geo-replication to
  create files on slave mount with same gfids as that on master.
  It will also help gsyncd to access files directly through their
  gfids. gsyncd in its newer version will be consuming a changelog
  (of master) containing operations on gfids and sync corresponding
  files to slave.

* Also, bring in support to heal gfids with a specific value.
  fuse-bridge sends across a gfid during a lookup, which storage
  translators assign to an inode (file/directory etc) if there is
  no gfid associated it. This patch brings in support
  to specify that gfid value from an application, instead of relying
  on random gfid generated by fuse-bridge.

  gfids can be healed through setxattr interface. setxattr should be
  done on parent directory. The key used is "glusterfs.gfid.heal"
  and the value should be the following structure whose contents
  should be in network byte order.

  typedef struct {
        char      gfid[UUID_CANONICAL_FORM_LEN + 1]; /* a null terminated gfid
                                                      * string in canonical form
                                                      */
        char      bname[]; /* a null terminated basename */
  } __attribute__((__packed__)) fuse_auxgfid_heal_args_t;

  This feature can be used for upgrading older geo-rep setups where gfids
  of files are different on master and slave to newer setups where they
  should be same. One can delete gfids on slave using setxattr -x and
  .glusterfs and issue stat on all the files with gfids from master.

Thanks to "Amar Tumballi"  and "Csaba Henk"
 for their inputs.

mount/fuse: Provide option to use/not use kernel-readdirp

2013-07-12T14:36:05+00:00

By default fuse kernel readdirp usage in fuse xlator is off.
When mount option use-readdirp=yes is provided it starts using
fuse-kernel's readdirp.

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.

glusterfsd: consider xlator type too in topology check

2013-06-21T09:40:05+00:00

When cluster.nufa option is enabled, we only change the translator
type, but leave the translator name as-is. This results in the
topology change check to conclude that a graph switch is not needed.

glusterfsd: dump the in-memory graph rather than volfile

2013-03-25T06:30:46+00:00

Currently we have been printing in the logfile, the volfile
verbatim as received from the server. However we perform
pre-processing on the graph we receive from the server, like
adding ACL translator, applying --xlator-option cli params,
etc.

So print the serialized in-memory graph as the "volfile" in
the log. This can be very handy to double check if certain
--xlator-option param actually got applied or not, and in
general is showing a "truer" representation of the real graph
actually used.
