RN102 Increase HDD
I have a RN102 with 2 x 2 TB HDD's configured as RAID1. I want to replace the disks with 2 x 4 TB HDD's (without losing data) Am I correct that the following : replace one 2TB disk with a new 4...
Hi, thank you for the reply.
I'm aware of WD RED being SMR now. WD should never having used the name WD RED for the SMR-disks. Created (and creates) a lot of confusion and source of problems for people not knowing the change.
But the two 4TB disks I have are WD RED Plus, so CMR.
So I was correct with the procedure, I assume all can been done hot-swap ?
Thanks

Correct.
Netgear does recommend doing a backup first, as if one of the existing disks fails during the resync you can lose data.
The actual configuration being a 2TB RAID1, there are actually two Healthy copies which makes me think I can proceed without backup ? If something goes wrong with the first HDD, I still have the second one.

Keeping the 2 TB drives intact until the procedure completes does give you reasonable fallbacks if something goes wrong.
