So I've got a handful of oVirt nodes now, and most of them have over 100G of unallocated disk space. I'm trying to figure out how to best take advantage of that space. I see two possibilities: storage for oVirt, or backup/archive storage.
I'm currently using a single NFS server for VM/iso/export storage (oVirt 3.3.x on CentOS, if it matters) and don't need to scale to hundreds of nodes (probably 10-20, max). Is current gluster support stable enough for production? What are the pros/cons of gluster vs NFS? I like the idea of not having a single point of failure but worry about performance. The other option is to stick with my NFS server and use the extra storage for archive/backup space. Here I'm looking for reliability (i.e. losing a server won't cause data loss) over performance. Are there pros/cons to gluster vs ceph? Will either/both peacefully co-exist with an ovirt node? All suggestions welcomed. Thanks! Robert -- Senior Software Engineer @ Parsons
