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:

1. Change configs to use gen 2 PCI, currently it’s set to gen 3, but AFAIK pi 5 does not support gen 3 officially.
2. 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.

Whatever, I’m using it regardless of what shitty commercial alternatives tried to be shoved down my throat. If Draw.io goes shit I’ll just switch to ditaa

At least they are not a tee pot

I love waterfall as an developer, I’m using agile now and we have incomplete, conflicting designs every sprint, or spills which affect our metrics, where in waterfall you can workout all the details and have full vision of product and better design with less reworks.

Not to mock you. My point is that methodology is not import when team consists from responsible professionals
