Hello together
I do need some help, I get an error report from my freenas:
" One or more devices has experienced an unrecoverable error. An
attempt was made to correct the error. Applications are unaffected."
I've found some checksum errors on all 3 disks (3 * WD Red 3TB), what does this mean to my zfs system is it corrupted? What do I have to do know? Can the system heal itself?
I don't use ECC Ram, but I have tested the RAM with ramtest and it is fine.
Thx for your help.
