Greetings all, and Happy Friday;
I'm running oVirt 3.6 management engine that is currently overseeing 4 compute nodes, attached to iSCSI storage over Infiniband. The compute nodes have 8 hot-swap hard drive slots, with each only having 2 slots occupied in a hardware RAID array level one for the hypervisor to live on.
Would it be possible for me to set up each compute node with a second array in the remaining 6 hot-swap slots, and utilize that new space for a nice fault tolerant GlusterFS storage array ?
That schema is called hyper-converged. Please see: https://fosdem.org/2016/schedule/event/virt_iaas_ovirt_hyperconverge/attachm... Take care that currently it's not production ready.
1. Would the system allow me to add the Gluster storage to the existing datacenter/cluster that is currently using iSCSI ?
2. Would I be able to configure all aspects of the Gluster environment(except the hardware RAID array)through the GUI ?
3. What hardware RAID level would be optimal for this configuration ? (RHEV documentation says RAID 6 is "Mandatory")
4. Will the system support live migration between storage domains ?
I'm reading through the gluster documentation now to get a better understanding of it's inner workings. Is there a good source for Gluster on oVirt that i can reference as well ?
