TS-873A Built-in NVME Raid1 Cold Swapping

Post by steakikan »

Hi, I plan to build a new NAS system with planned 2 NVME 500gb drive for OS and 8 HDD for ZRAID7 (2 for hot standby), the confusing part is if I put the OS on the built in NVME slot how could I replace the drive if one is failing? As the built in NVME slot doesn;t support hot swapping? Is it possible to cold swap the RAID1 on the OS drive?

Not a problem, it is not for high speed usage and more for cold data purposes.

Will the system automatically switch? My TS-469-Pro doesn't do anything when I do cold swap replacement on Raid 1 and keep asking the old disk.

you'd hope so..but cold swap is the only thing to do (cat2 units were always better with cold swapped drives than older cat1)

It should. I've changed the internal M.2 diiscs of my TS-1635AX this way. System noticed the WWN change and started to rebuild the drive. After doing this twice, I could expand the Array as any other.

You could try the replace one by one wizard to trigger the change manually. But it worked for me by just cold swapping.
