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. <br>
<br>
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):</font><font size="3"> <br>
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. <br>
You have to "volume set server.allow-insecure on" option and
bind-insecure option.<br>

option correctly

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. <br>
<br>
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: </font><a

both replicated_vol-client-0

I could not find a 'remote-port' option in /var/lib/glusterd on
either

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.</font><font size="3"> <br>
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'</font><font
