I currently have 3 nodes, one is the engine node and 2 Centos 7 hosts, and I plan to add another Centos 7 KVM host once I get all the vm's migrated. I have san storage plus the raid 5 internal disks. All OS are installed on mirrored SAS raid 1. I want to use the raid 5 vd's as exports, ISO and use the 4TB iscsi for the vm's to run on. The iscsi has snapshots hourly and over write weekly. So here is my question: I want to add glusterfs, but after further reading, that should have been done in the initial setup. I am not new to Linux, but new to Ovirt and need to know if I can implement glusterfs now or if it's a start from scratch situation. I really don't want to start over but would like the redundancy. Any advice is appreciated. Eric
You can add it in to a running ovirt cluster, it just isn’t as automatic. First you need to enable Gluster in at the cluster settings level for a new or existing cluster. Then either install/reinstall your nodes, or install gluster manually and add vdsm-gluster packages. You can create a stand alone gluster server set this way, you don’t need any vddm packages, but then you have to create volumes manually. Once you’ve got that done, you can create bricks and volumes in the GUI or by hand, and then add a new storage domain and start using it. There may be ansible for some of this, but I haven’t done it in a while and am not sure what’s available there. -Darrell

Just a hint -> use thin LVM if you wish to use gluster snapshots (which is a nice feature) . I'm using gluster snapshots for my HostedEngine , as it is on a dedicated volume. Best Regards, Strahil Nikolov
I originally set my SDM on an iscsi lun 4TB but Ovirt moved it to a raid 5 internal disk on one of the hosts. How can I force Ovirt to make the 4TB lun the storage domain master? That’s where I want to vm's to reside.
