glusterd: cleanup unneeded volumes after peer detach

2011-10-01T12:54:56+00:00

Performs cleanup on the detached peer and in the cluster after a
peer detach, and also adds a new check before starting detach.

Cleanup -
 On the detached peer, cleanup removes the entries of those volumes
on the peer that do not have all their bricks on it. This prevents
these stale volumes from being added to a new cluster when peer is
attached to one.
 In the cluster, all those volumes which have all their bricks on the
detached peer are removed.

Checks-
 Checks if all the peers in the cluster are online and connected,
 except the peer being detached, before starting detach. Using force
 will bypass this check and do detach.

cli : new volume statedump command

2011-09-27T13:45:10+00:00

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  [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,
        ..dump

modify to the way we used XDR definitions files (.x files)

2011-09-07T17:48:52+00:00

Earlier:
step 1: copy the existing .x files to /tmp
step 2: generate '.[ch]' files using 'rpcgen .x'
step 3: check diff with the to the existing files, add only your part
        of changes back to the original file. (ignore other changes).
step 4: there is another file to write wrapper functions to convert
        structures to/from XDR buffers, update it with your new structure.
step 5: use these wrapper functions in the newly written procedures.
step 6: commit :-|

Now:
step 1: update (mostly adding only) the .x file
step 2: run '/extras/generate-xdr-files.sh .x' command
step 3: implement rpc procedure to handle the request/response.
step 4: commit :-)
