Just added a new Seagate 16TB drive to my Unraid. Initial zeroing took about one day, and went by without a hitch. Formatted the drive, and added it to the array. Then had time to move about 50GB onto it before Unraid warned me about SMART errors. So I cancelled the move and used unbalance to scatter everything off it.
SMART overall-health self-assessment test result is PASSED... But here are the counters that errored:
5 Reallocated_Sector_Ct PO--CK 100 100 010 - 19
187 Reported_Uncorrect -O--CK 090 090 000 - 10
197 Current_Pending_Sector -O--C- 100 100 000 - 1
198 Offline_Uncorrectable ----C- 100 100 000 - 1
(full SMART log attached)
At this point, the drive is completely empty and has 22 hours of total uptime.. Is it normal to have a few bad sectors, or should I just RMA the drive straight away, as is my immediate inclination? (my first time encountering SMART errors..)
Additionally, some questions on how to proceed here:
I don't have a replacement drive sitting around, so probably looking at 1-2 weeks for a replacement to arrive. In the meantime, can I just remove the faulty data drive from the array (again: it's empty, but not sure if parity "cares") or would I need to fully rebuild parity in that case anyway?
Alternatively, could I safely run the array with one missing data drive? Then, once the replacement drive arrives, just put it back in and rebuild? (essentially rebuilding nothing as the drive is empty)
Any suggestions on doing a secure wipe before RMA? nwipe?
