[ovirt-users] New HCI with gluster
I am performing a new install of 3 nodes
ovnode1 - 3 disks,install on first two disks
ovnode2 - 3 disks,install on first two disks
ovnode3 - 3 disks,install on first two disks
Storage network interfaces are configured with 192.168.xxx.10 no gateways
configured for this network
Data network interfaces are configured with 10.3.x.10
When i run the wizard it always fails. All 3 hosts are running the latest
stable (4.3.9). I have attached the log files from the runs on these hosts

Re: [ovirt-users] Firewall?
Thanks livnat, but i don't really understand . The security group feature defines iptables rules on the note itself. About that: how can i define security group rules ? and in a cluster, they are automatically propagated al all nodes ?

thanks, but i mean how to obtain this information from Ovirt manager layer .. i don't want install snmp in the single VM.. because customer can disable it … Il giorno 05/mag/2014, alle ore 10:38, Meital Bourvine mbour...@redhat.com ha scritto: Hi, You can get the information via snmp - here you can find some useful OIDs [1]. If I were you, I would have considered monitoring the VMs with zenoss [2] (which uses snmp and already has all relevant OIDs). It has a python api, so for creating the web page - I would have probably use django [3] with zenoss' python api. With that being said, there might be a way that I'm not aware about to get this information from ovirt.
