<br>
I am running a field trial of Gluster 3.5 on two servers.
These two server use one 10k HDD each with XFS as a brick. On
top of these bricks I have one replica 2 volume: <br>
<br>
[root@nodef01i ~]# gluster volume info ph-fs-0 <br>
<br>
Volume Name: ph-fs-0 <br>
Type: Replicate <br>
Volume ID: 5085e018-7c47-4d4f-8dcb-cd89ec240393 <br>
Status: Started <br>
Number of Bricks: 1 x 2 = 2 <br>
Transport-type: tcp <br>
Bricks: <br>
Brick1: 10.11.100.1:/gfs/s3-sata-10k/brick <br>
Brick2: 10.11.100.2:/gfs/s3-sata-10k/brick <br>
Options Reconfigured: <br>
performance.io-thread-count: 12 <br>
network.ping-timeout: 2 <br>
performance.cache-max-file-size: 0 <br>
performance.flush-behind: on <br>
<br>
Additionally I am running nagios to monitor everything where I
use <a moz-do-not-send="true" class="moz-txt-link-freetext"
href="http://exchange.nagios.org/directory/Plugins/System-Metrics/File-System/GlusterFS-checks/details">http://exchange.nagios.org/directory/Plugins/System-Metrics/File-System/GlusterFS-checks/details</a>.
I improved it slightly such that I monitor number of
split-brain files and all this information go to the
performance data, therefore I can draw pictures out of it
(these pictures are in attachement). <br>
<br>
My problem is that I am receiving quite a lot of false warning
from nagios during a day because there are some unsync files
(gluster volume heal XXX info). I dont know if it is a bug or
it is cause by my configuration. Either way it is quite
disturbing and I am afraid that after receiving a lot false
warning I could just omit an important one.. <br>

I think the issue is because the "gluster volume heal info" also
reports files undergoing I/O in addition to files that need
self-heal. see <a moz-do-not-send="true"
class="moz-txt-link-freetext"

for more information on this. Pranith, please correct me if
wrong.<br>
<br>

It makes sense, but it is quiet inconvenient to check logs to be
sure what is actually I/O and what is healing.. So I support this
initiative! Do you have any idea when it is going to be
implemented? <br>

These projects also look very interesting. I was googling, but I
didnt find the way how to install addon to glusterfs. Can you
please give me a hint? I would like to install it, test it and
maybe I can write some patches..<br>
