As the question insinuates, I'm green to networking, but had built my own NAS box a few years ago. Here's my build for reference:
- ASRock C2550D4I Mini ITX Server Motherboard
- Crucial 16GB (2 x 8GB) 240-Pin DDR3 SDRAM ECC
- 4x Seagate 4TB NAS HDD
I set it up as RAID-Z2
Everything had always run smoothly. Upgraded to FreeNAS 11.1 STABLE release. Until about a month ago when I received the following warning on the dashboard:
Critical error: The boot volume state is ONLINE: One or more devices has experienced an error resulting in data corruption. Applications may be affected.
Doing some reddit and google searches, looked like I needed to do a fresh OS install. Which I attempted, but then when I shut down the NAS box to do a reinstall of FreeNAS, my motherboard wouldn't "POST". not even sure i'm describing that correct... got no VGA output, couldn't connect to the network, couldn't boot from USB. I accessed the board thru IPMI, worked with ASRock customer support, and they said I should submit an RMA and return the board under warranty (they didn't explain what it was that they saw that required a warranty claim).
This is fine, I suppose. But my main question is whether my data shares are safe. So far the reddit resopnse and the ASRock customer support have said they should be safe, as the motherboard and the OS dont operate on the hard drives themselves.
Looking for reassurance, I guess.
