dht/rebalance: set the correct ownership on the dst file.

2012-08-30T09:45:51+00:00

Currently, the dst file created has root:root ownership, till
migration is completed. During this phase, open fails on the dst
file if uid/gid is non-root.
Setting the dst_file to the correct ownership fixes the issue

cluster/dht: Remove dht dependency on glusterfsd-mgmt

2012-08-02T03:57:30+00:00

glusterfs_ctx->notify can be used by any xlator to talk to
glusterfsd-mgmt.
Note- This is for any rpc communication initiated by the xlator,
      and not from glusterd.

Also no need to free the xlator object after rebalance is over, as the process
is about to be killed.

distribute: use global synctask 'env' instead of local

2012-05-29T13:29:59+00:00

creating a local synctask_env can lead to creating of many more
syncop threads than required. The current syncop logic can handle
the scale-up/scale-down of threads depending on the load. Hence,
its neater to use global synctask env.

Status is updated by event_notify handshake by the rebalance process.
If there is disconnect, before rebalance process, only then the
state is moved to failure.

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.
