glusterd: Should not cleanup peerinfo too soon.

2011-09-27T12:44:09+00:00

friend_remove_cbk cleans up peerinfo and the unrefs the associated rpc_clnt
obj. When the cbk is run inside call_bail or saved_frames_unwind, we might end
up destroying the rpc_clnt and associated saved_frames_pool while we are still
using saved_frames to iterate through the frames.

glusterd: support for resetting single option

2011-09-27T12:38:36+00:00

Allows resetting of only single options using 'volume reset' command.
New syntax of volume reset is: 'volume reset [option] [force]'.
Giving "all" as options or not specifying an option, causes all options
to be reset.

glusted: while doing add-brick, handle distribute volume separately

2011-09-27T12:35:03+00:00

so the logic of different type of counts etc won't come into action,
which would fail the add-brick operation.

glusterd: cleanup of volinfo '*_count' definitions

2011-09-23T13:48:32+00:00

earlier, sub_count was having different meaning depending on the
volume type.

now, for replica and stripe count, one can directly access the
'replica_count' or 'stripe_count' to get the corresponding
value from the volume info. 'sub_count' is preserved as is for backward
compatibility. there is a new variable 'dist_leaf_count' to get
info about how many bricks are present in one distribute sub volume.

Peer probe: Handle probe of friend with multiple hostname

2011-09-22T11:52:47+00:00

Currently, when a peer is probed with a different hostname already belonging
to a cluster, a duplicate entry is created with uuid to set to 0.
This leaves the peerinfo in a inconsistent state, and when a detach of
this peer is issued, the correct entry gets removed.

The fix is to identify a peer with a hostname not matching to the probed
hostname and remove the incorrect entry.

glusterd now checks if a brick process is running to set online status,
instead of using brickinfo->signed_in. The earlier method used to show
incorrect online status as brickinfo->signed_in was not updated when
brick process was killed with SIGKILL
