Recently build a new striped RAIDz3 of 14 drives, last night I received an email that 2 drives have 4 checksum errors.
That is what zpool status output shows, when I pull smart data for all the drives with the smart report script there are no drives with SMART errors.
What is the best way to proceed? The 14 drives were burned in for 7 days, completing 10 ore more passes each, and after completing those passes ran SMART long tests on each and pulled SMART for all of them and showed no errors.
System Specs:
FreeNAS Server 9.3
Supermicro X9DR3-LN4F+ , dual E5-2670 @ 2.60Ghz with noctua heatsinks
96GB of RAM
M1015 with 2 SAS cables to the backplane
Dual 80GB Intel SSD's for boot
x7 4TB WD Red's RAIDz3
x14 2TB WD RE4's Striped RAIDz3
x14 2TB WD RE4's Striped RAIDz3
Chelsio T420-CR 10GB card
Supermicro SC846E16-R1200B case
