I have 3x2TB disks set-up with radiz1. All disks are less than 6 months old.
A week or so ago, i started getting some errors saying that one of the disks was offline, i think this was due to a faulty molex connector. I now seem to have some bad blocks on two of the disks. I was about 90% through copying a 10GB file to my NAS when the disks went offline, causing the file to become corrupt.
zpool status:
I have deleted the above file and scrubbed the pool, but it continues to deleted that file...
I am also getting a lot of checksum errors:
Looking at the above, i would say i need to replace two disks, is that right?
Why does zpool status -v continue to show the permanent error even after the file has been deleted?
I have tried to take one of the disks offline so i can replace it, but i comes back with the below. Why could this be?
Also, it seems weird that the disks don't appear as ada0,ada1 and ada2.
Thanks for you help!

Why does zpool status -v continue to show the permanent error even after the file has been deleted?
I have tried to take one of the disks offline so i can replace it, but i comes back with the below. Why could this be?
Code:
[...alex@NAS] /mnt/Media# zpool offline Media gptid/8cd2bb1c-db54-11e0-b3ad-e0cb4eb75f95

Also, it seems weird that the disks don't appear as ada0,ada1 and ada2.
Thanks for you help!
