Ok, more updates here:
I turned on trace and it seems bind to secure port on the mount client
with the remote brick is successful - afterwards the connect() fails to
complete. I saw these logs:

After that, I attached the mount process to my gdb session and attached a
breakpoint at __socket_shutdown(). It gave me the following traceback

In case somebody could give me a clue or two on my next move (I'm looking
at the code in the meantime), I'd be very grateful.

Hi Pranith,
I finally understood what you meant the secure ports, because the issue
occurred in one of our setups once more. It seems one of the clients on
serv1 could not open a connection to the glusterfsd running on serv0. I'd
actually started a mail trail about it (believing it might be something
else, initially) here:
http://www.gluster.org/pipermail/gluster-users/2015-February/020465.html
I think I can write me a rudimentary kind of patch altering
af_inet_bind_to_port_lt_ceiling() to get it to call bind with port 0,
rather than specify a port explicitly when the client.bind-insecure is
specified ...
Then I'd need to create a way to set server.allow-insecure using the cli
(or if you already sent around the patch to do that like you said in the
earlier mail, do let me know). I'll keep you posted about it round here or
@ [gluster-devel] if I can get it to work.
Thanks a lot,
Anirban

Oh, I didn't I only read a fragment of the IRC log and assumed
--xlator-option would be enough. Apparently it's a lot more work....
I do have a query, though. These connections, from one of our setups, are
these on secure ports? Or, maybe I didn't get it the first time.....

We'll set this option on our test servers and keep the setup under
observation.
How did you get the bind-insecure option working?
I guess I will send a patch to make it 'volume set option'

Hi Pranith,
Yes, the very same (chalcogen_eg_oxygen at yahoo.com). Justin Clift sent me a
mail a while back telling me that it is better if we all use our business
email addresses so I made me a new profile.
Glusterfs complains about /proc/sys/net/ipv4/ip_local_reserved_ports
because we use a really old Linux kernel (2.6.34) wherein this feature is
not present. We plan to upgrade our Linux so often but each time we are
dissuaded from it by some compatibility issue or the other. So, we get
this log every time - on both good volumes and bad ones. What bothered me
was this (on serv1):
Basically to make the connections to servers i.e. bricks clients need to
choose secure ports i.e. port less than 1024. Since this file is not
present, it is not binding to any port as per the code I just checked.
There is an option called client-bind-insecure which bypasses this check.
I feel that is one (probably only way) to get around this.
You have to "volume set server.allow-insecure on" option and bind-insecure
option.
CC ndevos who seemed to have helped someone set bind-insecure option
correctly here (http://irclog.perlgeek.de/gluster/2014-04-09/text)

When I write on the good server (serv1), we see that an RPC request is
sent to both client-0 and client-1. While, when I write on the bad server
(serv0), the RPC request is sent only to client-0, which is why it is no
wonder that the writes are not synced over to serv1. Somehow I could not
make the daemon on serv0 understand that there are two up-children and not
just one.
One additional detail - since we are using a kernel that's too old, we do
not have the (Anand Avati's?) FUse readdirplus patches, either. I've
noticed that the fixes in the readdirplus version of glusterfs aren't
always guaranteed to be present on the non-readdirplus version of the
patches. I'd filed a bug around one such anomaly back, but never got
around to writing a patch for it (sorry!) Here it is:
https://bugzilla.redhat.com/show_bug.cgi?id=1062287
I don't this has anything to do with readdirplus.
Maybe something on similar lines here?
Thanks,
Anirban

Hello,

replicated_vol is mounted at /mnt/replicated_vol on both serv0 and serv1.
If I do the following on serv0:
root at serv0:~>echo "cranberries" > /mnt/replicated_vol/testfile
root at serv0:~>echo "tangerines" >> /mnt/replicated_vol/testfile
And then I check for the state of the replicas in the bricks, then I find
that
root at serv0:~>cat /mnt/bricks/replicated_vol/brick/testfile
cranberries
tangerines
root at serv0:~>
root at serv1:~>cat /mnt/bricks/replicated_vol/brick/testfile
root at serv1:~>
As may be seen, the replica on serv1 is blank, when I write into testfile
from serv0 (even though the file is created on both bricks).
Interestingly, if I write something to the file at serv1, then the two
replicas become identical.
root at serv1:~>echo "artichokes" >> /mnt/replicated_vol/testfile
root at serv1:~>cat /mnt/bricks/replicated_vol/brick/testfile
cranberries
tangerines
artichokes
root at serv1:~>
root at serv0:~>cat /mnt/bricks/replicated_vol/brick/testfile
cranberries
tangerines
artichokes
root at serv0:~>
So, I dabbled into the logs a little bit, after upping the diagnostic
level, and this is what I saw:

0-replicated_vol-replicate-0: Building lookup response from 0
We see that when you write on serv1, the RPC request is sent to both
replicated_vol-client-0 and replicated_vol-client-1, while when we write
on serv0, the request is sent only to replicated_vol-client-0, and the
FUse client is unaware of the presence of client-1 in the latter case.
I checked a bit more in the logs. When I turn on my trace, I found many
instances of these logs on serv0 but NOT on serv1:

Logs above suggest that mount process couldn't assign a reserved port
because it couldn't find the file
/proc/sys/net/ipv4/ip_local_reserved_ports
I guess reboot of the machine fixed it. Wonder why it was not found in the
first place.

reading from socket failed. Error (No data available), peer
(192.168.24.81:49198)
I could not find a 'remote-port' option in /var/lib/glusterd on either
peer. Could somebody tell me where this configuration is looked up from?
Also, sometime later, I rebooted serv0 and that seemed to solve the
problem. However, stop+start of replicated_vol and restart of
/etc/init.d/glusterd did NOT solve the problem.
Ignore that log. If no port is given in that volfile, it picks 24007 as
the port, which is the default port where glusterd 'listens'
Any help on this matter will be greatly appreciated as I need to provide
robustness assurances for our setup.
Thanks a lot,
Anirban
