I have an external eSATA enclosure with six drives mounted in it, but offers no RAID features so each drive is seen individually. I wish to set them up as a software RAID 5.

The question I have is in regards to whether it's possible to physically transfer and mount the array on a different linux box in case of emergencies.

Is this reasonably do'able with minimal amounts of pepto bismol?

Certainly. No problem at all.
A scan of the partition headers of any disk in the array will provide the UUID, which is all it takes to start the array.

Sounds promising. Is there anywhere that I can find the commands and instructions to do so? I'd like to test doing it so that I know how to do it when necessary.
