Thanks a lot, Pranith.
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@yahoo.com_
<mailto:chalcogen_eg_oxy...@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,

replicated_vol is mounted at /mnt/replicated_vol on both serv0 and
serv1. If I do the following on serv0:
root@serv0:~>echo "cranberries" > /mnt/replicated_vol/testfile
root@serv0:~>echo "tangerines" >> /mnt/replicated_vol/testfile
And then I check for the state of the replicas in the bricks, then I
find that

tangerines

root@serv1:~>cat /mnt/bricks/replicated_vol/brick/testfile

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@serv1:~>echo "artichokes" >> /mnt/replicated_vol/testfile
root@serv1:~>cat /mnt/bricks/replicated_vol/brick/testfile

root@serv0:~>cat /mnt/bricks/replicated_vol/brick/testfile

So, I dabbled into the logs a little bit, after upping the diagnostic

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:

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.
