[ovirt-users] [ovirt-devel] oVirt 3.5 beta2 - results

[Piotr Kliczewski]

Hi all,

I tested gluster related features:


Nagios Integration -> http://www.ovirt.org/Features/Nagios_Integration#HOW_TO

I installed Nagios dependencies on f20 which went smoothly but when I
did the same for rhel6 I noticed that I had to install manually
additional rpm which was not covered by howto.

rrdtool-perl-1.3.8-6.el6.x86_64.rpm

During discovery of the Nagios server I got following issue:

[root at rhel gluster]# /usr/lib64/nagios/plugins/gluster/discovery.py -c
Default -H 192.168.1.9
Failed to execute NRPE command 'discover_volume_list' in host '192.168.1.9'
Error : Make sure NPRE server in host '192.168.1.9' is configured to
accept requests from Nagios server

so I followed http://tecadmin.net/install-nrpe-on-centos-rhel/.

Nagios server reported status of the cluster. When I had configured
first nagios server I saw:

"OK : None of the Volumes in the cluster are in Critical State "

but for the second there was:

(null).

I followed howto and installed oVirt UI plugin but after restart I was
not able to see monitoring details tab so I opened:
https://bugzilla.redhat.com/show_bug.cgi?id=1124371




Volume performance stats ->
http://www.ovirt.org/Features/Gluster_Volume_Performance_Statistics#HOW_TO

I reused already existing setup. I enabled stats and added a volume.
When checking stats details I saw "could not fetch stats".

I wanted to generate some stats so I mount volume previously created using:

mount -t nfs 192.168.1.9:/vol1 /media/volume

I had to redo it several times do to:

mount.nfs: requested NFS version or transport protocol is not supported

After several attempts I lost connectivity to the machine. After host
recovered I tried to run:

mount -o mountproto=tcp -t nfs 192.168.1.9:/vol1 /media/volume

but the result was the same.

I opened: https://bugzilla.redhat.com/show_bug.cgi?id=1124376


I checked whether gluster still works with jsonrpc. I removed the host
that I installed before and added new one using jsonrpc protocol.
After the installation I noticed that host was moved to Non-Operation
state. In the logs I found:

{"jsonrpc": "2.0", "id": "101bf460-6529-42d6-9370-a9629daad628",
"error": {"message": "The method does not exist / is not available.",
"code": -32601}}

I checked what was the reason and there was no apiwrapper.py module so I opened:

https://bugzilla.redhat.com/show_bug.cgi?id=1124481



Thanks,
Piotr
