Hello
I have the following in my truenas view:
When going into "status" for that pool I get this:
I see that there is a checksum error, I have done a "resilver" but that did not resolve it...
When looking at the SMART status for each drive I get this:
Ada2:
Ada1:
So as far as I can see there are no issues with the drives, no point in sending them in for a replacement, but there is an issue with the pool, how can I fix this, or am I missunderstanding something? My knowledge in all of this is low so most likely I am missunderstanding something...
