glusterd: Run post hooks on a different thread

2012-05-29T10:20:37+00:00

This change ensures post hooks can 'wait' if need be
and _not_ prevent glusterd from being able to run other operations
meanwhile.

Also ensures that post hook scripts are 'serialized'
between transactions. ie, post hook scripts of txn1 are completed
before post hook scripts of txn2 are started, where txn1 happens before
txn2.

glusterd/store: Move remove-brick/rebalance status to node_state.info

2012-05-05T13:20:42+00:00

Hence forth, all node related info, which does not need chksum or
versioning can be stored in this file. This data might not be in
sync across nodes, as it contains only information related to
local node.

rebalance: handshake_event_notify to make fsd talk to glusterd

2012-04-25T11:05:35+00:00

Event_notify can be used by others to communicate with glusterd.
A cbk event is also added for future use.

req has a op, and dict.
rsp has op_ret, op_errno, and dict.

With this, rebalance process can update the status before
exiting.

glusterd : Fixes for breakages caused by volume-id validation

2012-04-17T13:26:15+00:00

Fixes glusterd_op_build_payload() to,
1. take account of status cmd type when building payload for "volume status" to
   prevent "volume status all" from failing.
2. take account of volname being "help/help-xml" in volume set to prevent
   "volume set help/help-xml" from failing
3. obtain volname using key "master" prevent "volume geo-replication" commands
   from failing

Also, fails op and sets correct op_errstr if volume not found during
glusterd_dict_set_volid(), to make sure cli displays proper message.

glusterd: fix bugs of syncop for operations

2012-03-22T11:19:18+00:00

* free the stack created for synctask
* use different key than 'operation' in dictionary as thats being used
  already by other glusterd operations
* send proper frame to 'rpc_clnt_submit()' API, as it gets used
  internally
* also make sure to destroy the above frame in all _cbk()
* move everything specific to synctask into one file, so it is easy to
  maintain

core: bring a cmdline option to set memory-accounting

2012-03-15T10:33:18+00:00

currently this is implemented as a command line option, and not
as an easier translator option. this is because as of now, before
even the volume files are parsed, we would need memory accounting
enabled. there is scope for improving this behavior, but for now,
this approach solves the problem.

Also, this feature's major consumers are the testers who are
looking for leaks, hence option is hidden from usage output.

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]
