Cloning System disk

[Taleya]

I know, I know, the holy grail, especially since I'm looking down the barrel of setting up 100+ units that are all pretty much identical except for a verrry specific registration on a client running through container station.

Requisites: NAS units are all the same model (and usually successive sns to boot), hard disks are all identical (same deal)

so far I've determined I can configure a NAS completely, take the drive out and stuff it in another NAS and it works fine. However, if I try to clone the Master - be it via clonezilla, DD or a physical bitcopier, nope, the clone won't work. NAS will pick up hey you've got a drive here, would you liek me to recover, but never, ever succeeds in doing so.

Somewhere in the bowels of the hard disk I suspect the NAS has written a config that holds the drive SN. Anyone know where it is?

EDIT: Cloning via RAID 1 won't work, once the RAID is broken it constantly bleats a drive error. Not good on a production machine and would disguise genuine issues. Removing the pool to reset the drive obviously trashes all the data I'm trying to duplicate.

you may use swap disk one by one
to make any number of raid members disk than use tham else ever device and restore raid by rebuuild

The build is a single disk though, not a raided array. So the only option I have is to migrate the raid group....which brings us back to the issue mentioned in the main post about breaking the RAID
