Hi,
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:
[root@nodef01i ~]# gluster volume info ph-fs-0
Volume Name: ph-fs-0
Type: Replicate
Volume ID: 5085e018-7c47-4d4f-8dcb-cd89ec240393
Status: Started
Number of Bricks: 1 x 2 = 2
Transport-type: tcp
Bricks:
Brick1: 10.11.100.1:/gfs/s3-sata-10k/brick
Brick2: 10.11.100.2:/gfs/s3-sata-10k/brick
Options Reconfigured:
performance.io-thread-count: 12
network.ping-timeout: 2
performance.cache-max-file-size: 0
performance.flush-behind: on
Additionally I am running nagios to monitor everything where I use
http://exchange.nagios.org/directory/Plugins/System-Metrics/File-System/GlusterFS-checks/details.
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).
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..
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
http://supercolony.gluster.org/pipermail/gluster-users/2014-May/040239.html
for more information on this. Pranith, please correct me if wrong.
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?
I
Pranith?
On another note, we are also developing Nagios plugins that can be
used to monitor the various entities and services in the gluster
cluster. The repositories are here -
gluster-nagios-addons -
http://review.gluster.org/#/admin/projects/gluster-nagios-addons
nagios-server-addons -
http://review.gluster.org/#/admin/projects/nagios-server-addons
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..
Have pushed a patch with instructions - http://review.gluster.org/#/c/7846/.
Please check this out and let us know. We look forward to your
contributions!
thanks
sahina
