Hello, Our cluster use NFS storage (on each node as data, and on a NAS for export) We currently have a huge problem on our cluster, and export VM as OVA takes lot's of time. I checked on the NFS storage, and it looks like there's files who might be OVA in the images directory, and OVF files in the the master/vms Can someone tell me if, when i install a new engine, there's a way to get this VMs back inside the new engine (like the import tools by example) Thank you a lot for your answers, Regards, Alexis ps : it should be said in the documentation to NEVER use backup of an engine when he is in a NFS storage domain on a node. It looks like it's working, but all the data are unsynch with reality.
