Ok, so last night my scheduled zpool scrub fired off critical errors on my boot pool. After checking the pool with zpool status -v freenas-boot, I get the following bad news:
So that leads me to a few questions. First of all, just how screwed am I? The fact that /boot/kernel/kernel is in the list is especially troubling. Are my boot devices toast? If so, that makes the 5th and 6th flash drives I've killed this year. It's getting ridiculous. However, all of the file errors are in the latest snapshot. Could I just roll back to the previous snapshot, delete the latest one, and then update again?
Beyond that, as I mentioned, this is getting ridiculous how quickly this thing eats flash drives and spits them back out. Does anybody know of a good flash drive brand/model that is known for long-term reliability? I know of the $150 industrial-grade drives, but I don't want to go that crazy. It just seems insane that I haven't yet had a single flash drive last longer than 6 months in this machine (and frankly, it terrifies me for how much I've trusted flash drives to store data without the error-detection capabilities of zfs...)
Thoughts? Suggestions? Condolences?
