I have a server that is running FreeBSD 6.2 with a RAID 5 via 3ware 9550 card. I believe the RAID volume is formatted as UFS. The OS is on a separate drive from the RAID. Would it be possible to install FreeNAS on a thumb drive without having to reformat the RAID? Would it recognize the RAID properly? Are there any steps I should take to make this happen?
