Question on my setup

[elev8]

Hi guys,
Sorry for the n00b question...
I have a DS420 with probably an unusual JBOD setup (don't ask).
I have drives in bayss 1, 2 & 3 (bay 4 is free). Each drive is it's own volume (ext4) in it's own storage pool.. so 3 drives, 3 slots, 3 storage pools, 3 volumes).
Drives are all in use with data on them.
Could I power down the unit, move the drives to different bays & keep the data intact? Or would I have to re-format/lose data?
In other words, would the NAS just detect the pre-existing pool/volume config at power-on, even though the drives may be in different bays?
Is it risky? (aside from risks related to handling/moving the drives), or should the DS-420 be expected to cope with this?

Thanks!

You can do it, but the question is why? What are you expecting or trying to do here?

Technically speaking, that is not JBOD. More like "Basic", though Synology permits SHR and JBOD with single drives.

This is fine. Drive position is immaterial.

Is it risky?

Far less risky that lacking drive redundancy. Presumably you have an off-NAS back-up.

Great. Thanks!
