I recently started setting up home server on Raspberry Pi 5. Having issues with raid1. I have 2 nvme PCIe gen 4 SSDs. There was power outages while writing. Now second disk keeps randomly falling. Though, I’m not sure if that’s the reason because I don’t know what was raid status before outage, also disk passes checks. First time it degraded, it tried to recover and it failed. I removed that disk from raid, recreated partition run some test using nvme-cli. Disk looked healthy. I re-added disk, rebuild started and completed successfully. Then I’ve written around 500Gbs of data and it degraded again. At that point I took a break.
There are two things I’m yet to try:
Change configs to use gen 2 PCI, currently it’s set to gen 3, but AFAIK pi 5 does not support gen 3 officially.
Remove, format and write data to problematic disk directly. I hope this will give me an idea is this hardware issue or software issue

I’m frustrated and will appreciate any hints.
