So,

 

Over the last few months i've been gradually retiring some old 2gb SAS drives (with escalating "Elements in grown defect list" errors) and replacing with some SATA 4Gb's.

 

As I run dual parity I could now retire my second shelf if I moved the drives into the spare bays in the server / shelf 1. (I've been using the zero method after clearing the data from the erroring drives - then removing when cleared)

 

From what I understand UnRAID doesn't care where the drives are physically - they are tracked by serial - so can someone confirm if I fill the redundant bays with the drives from/ shelf 2, and with screenshots ensure they are allocated the same position within UnRAID (this should be automatic) dual Parity will be maintained - the sda/sdb linux moniker is not relevent? 

 

It may annoy my OCD that drive25 maybe in bay 3 in my server and not bay 1 shelf 2, but I use "Disk Location" plugin so can track where drives are.

 

Is my thinking correct - I could do with removing shelf 2, if only to give my UPS a bit more headroom, and reduce some heat before we hit the 2 weeks of summer the UK has!

Correct, unless you're using RAID controllers or non standard enclosures, in which case the disks may not mount.
