If you are mounting a tcp,rdma volume using tcp protocol, all the
communication will go through the tcp connection and rdma won't come
in between client and server.<br>

</div>
<div>It’s what I do. But I note particularly this kind of
trouble when I mount my volumes manually.</div>
<div><br>
</div>
<div>In addition, when I changed my transport-type from
tcp or rdma to tcp,rdma, I have had to restart my volume

<div>I wonder if these trouble are not due to RDMA

one.</div>

</div>
<div>Another idea?</div>

Hi Niels,
<div><br>
</div>
<div>Thanks for replying. </div>
<div><br>
</div>
<div>In fact, after having checked the log, I've
discovered GlusterFS tried to connect a brick
with a TCP (or RDMA) port allocated to another
volume… (bug?)</div>
<div>For example, here is a extract of my
workdir.log file :</div>
<div>
<div style="margin: 0px; font-size: 11px;
font-family: Menlo; color: rgb(255, 255, 255);
background-color: rgb(0, 0, 0); position:

<div style="margin: 0px; font-size: 11px;
font-family: Menlo; color: rgb(255, 255, 255);
background-color: rgb(0, 0, 0); position:

21:34:01.822563] E
[socket.c:2332:socket_connect_finish]
0-vol_workdir_amd-client-2: connection to
10.0.4.1:49162 failed (Connexion refusée)</div>
<div><br>
</div>
<div>But the 2 ports (49161 and 49162) concerned
only my vol_home volume, not the
vol_workdir_amd one.</div>
<div><br>
</div>
<div>Now, after having restart all glusterd
synchronously (pdsh -w cl-storage[1-4] service
glusterd restart), all seems to be back into a
normal situation (size, write permission,
etc.)</div>
<div><br>
</div>
<div>But, a few minutes later, i note a strange
thing I notice since i’ve upgraded my cluster
storage from 3.5.3 to 3.7.2-3: when I try to
mount some volume (particularly my vol_shared
volume (replicated volume)) my system can
hang… And, because I use it in my bashrc file
for my environment modules, i need to restart
my node. Idem if I try to do a DF on my
mounted volume (if it doesn’t hang during the
mount).</div>
<div><br>
</div>
<div>With TCP transport-type, the situation
seems to be more stable..</div>
<div><br>
</div>
<div>In addition: If I restart a storage node, I
can’t use Gluster CLI (it also hang).</div>
<div><br>
</div>
<div>Do you have an idea?</div>
</div>
</blockquote>
<br>
Are you using bash script to start/mount the volume
? If so, add a sleep after volume start and mount,
to allow all the process to start properly. Because
RDMA protocol will take some time to init the
resources.<br>

I'm not sure how if the ping-timeout is
differently handled when RDMA is<br>
used. Adding two of the guys that know RDMA

</blockquote>
<br>
As seen further below, the 500GB volume is
caused by two unreachable<br>
bricks. When the bricks are not reachable, the
size of the bricks can<br>
not be detected by the client and therefore 2x
250 GB is missing.<br>
<br>
It is unclear to me why writing to a pure
distributed volume fails. When<br>
a brick is not reachable, and the file should
be created there, it<br>
would normally get created on an other brick.
When the brick that should<br>
have the file gets online, and a new lookup
for the file is done, a so<br>
called "link file" is created, which points to
the file on the other<br>
brick. I guess the failure has to do with the
connection issues, and I<br>
would suggest to get that solved first.<br>

I use GlusterFS in production since around 3
years without any block<br>
problem but now the situation is awesome
since more than 3 weeks…<br>
Indeed, our production are down since
roughly 3.5 weeks (with a lot<br>
and different problems with GlusterFS v3.5.3
and now with 3.7.2-3) and<br>
i need to restart it… <br>
<br>
Thanks in advance,<br>

looks like setting TCP_USER_TIMEOUT value

(IIUC) "Protocol not available".<br>
Could you check if 'network.ping-timeout'
is set to zero for that volume using
'gluster volume info'? Anyways from the
code looks like 'TCP_USER_TIMEOUT' can
take value zero. Not sure why it has
failed.<br>
<br>
Niels, any thoughts?<br>
