[Gluster-devel] Option transport.socket.bind-address fixes

[Emir Imamagic]

Hello,

glusterd has option transport.socket.bind-address that enables binding 
gluster to an exact IP address. This feature is necessary for HA cluster 
deployment. In the initial setup everything seemed fine, but after a 
little bit of testing I found several issues.

Here are the issues I found:
- NFS and selfheal daemons are started by glusterd but with volserver 
hard-coded to "localhost" (xlators/mgmt/glusterd/src/glusterd-utils.c). 
Since the glusterd is tied to a different address these two daemons fail 
to start.
- rebalance and quota sections in glusterd also invoke glusterfs with 
volserver hard-coded to "localhost" 
(xlators/mgmt/glusterd/src/glusterd-quota.c and glusterd-rebalance.c)
- bind-address is not propagated to the NFS volume file or other NFS 
daemons so all of them are listening on 0.0.0.0.

I provided a patch that solves these issues for version 3.4.1 using the 
SRPM from here:
 
http://download.gluster.org/pub/gluster/glusterfs/3.4/LATEST/EPEL.repo/epel-6/SRPMS/glusterfs-3.4.1-3.el6.src.rpm
Unfortunately I didn't use trunk because I need the patched version 
deployed as soon as possible. I've been running the patched version on 
my test environment  and it seems fine. Still I would be very grateful 
if someone can check if patches are any good.

Patch can be found here:
  http://kosjenka.srce.hr/~eimamagi/glusterfs-3.4.1.add.bind-address.patch
and SRPM with patch included here:
 
ftp://ftp.srce.hr/srce-redhat/base/el5/SRPMS/glusterfs-3.4.1-4.el5.srce.src.rpm

I hope this is something useful that can be included in future releases.

Best regards
