This is a limitation of the usb disks themselves, not ovirt-node. Older USB sticks don't respon to scsi_id calls and cannot be management by multipath. Newer usb sticks do work correctly with multipath and get picked up correctly. The only way to make it consistent would be to stop multipath from all usb sticks (not even sure that will work) but that's not optimal. The rule we follow is that we use multipath for devices that we can, and fall back to /dev/sd* when we can't. |
