I'm not sure how to use the '-v' command. I'm using fairly new drives, I got them around July - August 2021.

I'm not sure how I'm getting errors if it passed the SMART test.

Here is the error.

that needs to be done in the CLI, with zpool status -v.

SMART works on the disk level, ZFS is one level above that. Either it could be a disk issue SMART missed or an issue within ZFS.

I tried to do zpool clear and zpool scrub, but that didn't help. Is my only option to fix this issue is by wiping everything I have and redoing everything?
 
You definitely should recreate Dinodata4TB/vm-104-disk-0, and I think the other errors should be gone after running a scrub.
 
sorry for reviving an old thread but the error came back. i rebuilt my server with the newest proxmox version. after building a few vms i have erros in a few sectors:

do i really need to remake all my vms again?
 
Try starting zpool scrub and cancel it 2-3 times.
ex.
zpool scrub HDD4TB
zpool scrub -s
zpool scrub HDD4TB
zpool scrub -s
zpool scrub HDD4TB
zpool scrub -s
