Changing disk/RAID enclosure - problems?

Simple question: I have decided to replace my aging LaCie 5Big disk/RAID enclosure (which does not accept SSDs, as I discovered today) with a newer Thunderbay 6 model. As long as the used RAID disks do not change, would I risk losing anything or having to reformat everything if I move them to that new enclosure?

 

Thanks!

I assume you have the LaCie in "JBOD" mode and SoftRAID sees all the disks. If so, yes. you can just move the drives over.

@softraid-support Nope, it's three disks in RAID 5 mode - two other disks are being used separately.

You may be confused, if SoftRAID sees ALL the disks, then it is in JBOD mode.

If LaCie controls the disks, anotherwards, SoftRAID disk colume does not see the 3 disks, but just one, then it is controlled by hardware and you  cannot move it to another enclosure

JBOD is a setting on the LaCie end. When you use hardware RAID, the computer cannot even see the drives behind the "LUN (like a virtual disk) that is the hardware RAID.

the easy way to know is if SOftRAID sees 5 disks. If it does, you are OK. If it sees "3", (the RAID and two disks), then it is hardware RAID and you cannot move the disks.

@softraid-support There is no confusion - I have created a RAID 5 array with 3 disks on SoftRAID, and it only sees those disks on the left column (on the right column there is the RAID 5 "Volume" reference with three green lines connected to those three disks. Other disks are autonomous and not part of the RAID. In fact, my LaCie cannot even create RAID 5 by itself.
