[-- Attachment #1 --] I have a pile of 2Gb (more or less) SCSI hard disks laying around that I would like to bolt together into a RAID5 array using vinum. The trick is, all of the drives have slightly different sizes, varying from 2033Mb to 2048Mb. I know that the subvolumes have to be exactly the same size, but is that the partition, or the slice? I currently have them all dangerously dedicated to the full size of the drive, and I set the slices to be the same size. I have read all of the documentation I could get my hands on regarding vinum, but so far, I've found nothing that covers this. When I try to start the array, three of the disks come online, but the other three fail due to a size mismatch. From this, I would assume the partitions must be equally sized and the slices set to fill the partitions. Any ideas?
