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@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
