However, I've just bought three more 250GB disks that I also want to RAID5. I would still like a single volume, comprising the size of the two RAID5 volumes. Could this be possible through the use of RAID0? i.e. can I create a RAID0 volume from two RAID5 volumes? I understand this might sound a little odd but if it works it would be the ideal solution for me. I would also be interested in hearing how other people might have overcome this problem of growing a large RAID5 volume.
