protocol/client: Added lk_ctx info in fdctx dump

2012-03-07T18:17:41+00:00

- Added a brief explanation as to why we can't use gf_log
  when in statedump.

- Removed gf_log messages from client_priv_dump since
  it can cause a 'deadlock' - See statedump.c for explanation

- Added try-lock based accessors for fd_lk_list for dump purposes.

mempool: add more counters to understand the usage scenarios properly

2012-02-27T10:18:35+00:00

current design of mempool is to fallback to standard calloc/free if
all the buffers in pool are exhausted. Understanding more about those
numbers will help us to tune mempool parameters properly over time.

libglusterfs: Implement circular buffer and event history

2012-02-20T14:59:11+00:00

Implement circular buffer framework, so that it can be used by other components
such as event history management. And event history is implemented which can
be used by xlator to dump some information to a file (such as information of some
structure etc).

Through statedump, history of each xlator can be dumped. An option called history
should be given to the statedump command.

cli: Fix for statedump crashing gluster processes

2012-02-17T08:57:02+00:00

1. Fixes the bug in statedump causing the gluster process to crash when an unknown
option was given in the 'glusterdump.*.options' file.
2. Also fixes cli, making it send full statedump option strings even when only
partial option strings are given in 'volume statedump' command.
3. Minor change to order of operations during statedump to allow option parsing
errors to be written to the dump file.

statedump: do not print the inode number in the statedump

2011-10-01T12:55:22+00:00

    Since gfid is used to uniquely identify a inode, in the statedump
    printing inode number is not necessary. Its suffecient if the gfid
    of the inode is printed. And do not print the the inodelks, entrylks
    and posixlks if the lock count is 0.

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
