Help with errors in storage pool
Obligatory "I'm still fairly new to this", but hoping to get some help. I have a raidz1 pool with 3x8 TB drives in it. One of them went bad due to a brief power outage (running a UPS with it now) and so I replaced it. However, I now have some permanent errors in the pool and don't know how best to deal with them. Best I can tell, the three up top look like log files, but I'm not sure. The ones in the "truenas_catalog" folder look like app files, but I don't even have those installed. Is there something I'm missing?
Edit because I forgot to add:
I also see increasing numbers of checksum errors on all my drives. Same amount across each one. I had them connected through an HBA card with a breakout cable, so I swapped the cable. Errors still come. I reseated the card, still errors. I pulled the card out and plugged them into the onboard sata ports, but I am still getting errors. The drives themselves are in good shape. Two are new, one is less than a year old. Could this be related to the errors in the pool?
Thanks to any who read and comment.
