glusterfsd: Round robin DNS should not be relied upon with

2013-09-06T22:56:34+00:00

config service availability for clients.

Backupvolfile server as it stands is slow and prone to errors
with mount script and its combination with RRDNS. Instead in
theory it should use all the available nodes in 'trusted pool'
by default (Right now we don't have a mechanism in place for
this)

Nevertheless this patch provides a scenario where a list of
volfile-server can be provided on command as shown below

-----------------------------------------------------------------
$ glusterfs -s server1 .. -s serverN --volfile-id= \
      
-----------------------------------------------------------------
                   OR
-----------------------------------------------------------------
$ mount -t glusterfs -obackup-volfile-servers=: \
      :...: :/ 
-----------------------------------------------------------------

Here ':' is used as a separator for mount script parsing

Now these will be remembered and recursively attempted for
fetching vol-file until exhausted. This would ensure that the
clients get 'volume' configs in a consistent manner avoiding the
need to poll through RRDNS.

mgmt/glusterd, socket: Change logging for brick disconnects

2013-06-11T14:52:16+00:00

For unix path based sockets, the socket path is
cryptic (md5sum of path) and may not be useful for
the user in debugging so log it in DEBUG.

Changed logging in brick_rpc_notify to log brickinfo
for disconnects.

transport/socket: fix connect/disconnect races

2013-06-04T22:37:54+00:00

We might receive a connect request while a disconnect is still in
progress, requiring more states and (the return of) poller generation
numbers to avoid redundant pollers.  We might also get either kind of
request from within our own rpc_transport_notify upcall, so we have to
avoid locking and use the PLEASE_DIE state instead.

socket: Prevent extra logging in socket_rwv

2013-05-31T18:22:24+00:00

Problem:
If the socket is not even connected socket_rwv fails
and the error log comes every 3 seconds for every
re-connect.

Fix:
Prevent this error log if the socket is not even
connected.

socket: convert socket functions to file scope (static)

2013-05-29T12:26:57+00:00

The function names used in socket.c conflict with Samba's
socket functions (samba.git/source4/lib/socket/socket.h). Convert
our functions to file scope as they are anyways not called across
files.

Fix spurious brick disconnects

2013-04-29T21:25:05+00:00

Spurious disconnect were caused by a race condition inside
rpc_transport_ref()/rpc_transport_unref() that allowed the refcount
to drop to zero while the transport was still in use. The race
condition is made possible because of an uninitiaized mutex
produced when socket_server_event_handler() copies the transport
