Add SSD to RN528X
Hi Following on from https://community.netgear.com/t5/New-ReadyNAS-Users-General/Add-SSD-drive-s-to-RN528X/td-p/1776859 I've just had a go at adding an M2 SSD to my new 528X. It seems have wo...
The OS is treating the SSD like it's in another chassis. If it's on a different controller than the other drives, I can see it doing that. The OS will expand the OS (MD0, aka root) volume across drives in another chassis (such as an eSATA or SAS expansion), but it will not expand the swap partition except in the same chassis. That makes sense since the connection to the other chassis might be slow (like with eSATA). It does normally create that second partition, just not expand a volume into it. That allows you to move the volume to another NAS and it will boot.
Good to know the partition alignment doesn't seem to be an issue. Thanks for testing.
Interesting.
Just to note after a reboot (having added a 2nd HDD) the SSD became sdc (presumably as on a different controller).
I had to create the partition with sgdisk as mdadm failed:
sgdisk -n 3:0:0 -t 3:FD00 /dev/sdc
I also had to add --force to mdadm as it complained about a 1 disk array:
mdadm --create --verbose --force /dev/md126 --level=1 --raid-devices=1 --name=0a436c4c:M2SSD-0 /dev/sdc3
So I now have:

I'm afraid I'm out of ideas.

OK, so I checked my system, and I was mistaken about the swap partition. While it did create a partition for it on drives in my EDA500 on an RN516, though it didn't add them to the swap RAID, it has not done so on drives in my external SAS chassis. It does leave a space for it, though. So maybe try deleting the partition you created for swap.

There's a second discussion with the exact same title here:
(https://community.netgear.com/t5/New-ReadyNAS-Users-General/Add-SSD-drive-s-to-RN528X/m-p/1805740#M38176)but because it's from 2019 it must have been archived by NETGEAR because one cannot reply there anymore. Still, there is some quite useful info in it.
Just thought I should share this.
