Swapping hard drives from NAS to NAS

[rgarjr]

I have a LS421 2-bay NAS and just got the LS441 4-bay NAS.  Can I pull out a hard drive with data on it from the 2-bay and stick it into the 4-bay?  Configuration is JBOD

Would it format it immediately as I stick it in or would it see that it has the XFS partition and not?

Total different units. I wouldnt do that. Whether they use the same firmware or not. Just dont do that. What are you trying to do?

I know they are different units.  I understand the Firmware is installed on the primary drive (1st one installed) so I'm not going to move around that drive since of course the firmware is different for each NAS.  But the other drives, I don't know maybe I can.

I understand that if the drives are in RAID structure it would be impossible.  I'm not running that however, just JBOD.

I just want to move drives around.

Who told you the first drive has the OS? that's not true at all. Each drive has the OS on it. That why if you are in raid 0 or 1 or JBOD you can still boot with disk 2. I assume you want to xfer the data over to the other unit. It might work. or it might cause issues. confuse the unit and cause it to go in to em mode OR it can not load that disk. Its a 50/50. We had put some older disk in a newer unit and that mess everything up. Had to create a image of the firmware.. do some tinkering and bam unit is all good.
