When I checked the array this morning I noticed that Disk 6 had accumulated 33 errors overnight (there is still a green dot beside the disk). I ran a smart test for the disk which shows 5 for Current_Pending_Sector and 0 for the Reallocated_Sector_Ct. I have attached both the smart report and the relevant portion of the syslog. I'd appreciate some guidance on how to proceed. Cheers

disk 6 is having media errors and should be rebuilt. What are the system specs including number and model of HDD and PSU model?

The HDD in question is disk 6 of 16, a WDC WD15EARS-00Z5B1 and the PSU is a Corsair TX-650.

Are all drives WD15EARS-00Z5B1?

 

The PSU should be sufficient.

 

To rebuild the drive:

1. Start the array with disk6 unassigned.

2. Assign disk 6 and restart the array.

 

Rebuild will commence.

 

I suggest having a pre-clear spare ready in case disk6 fails completely.

Thanks for the suggestion. In order to minimize the downtime, I chose to swap in a precleared spare. Data rebuilding is in progress.

Cheers

Run pre-clear on the removed drive. The you can decide to RMA.

The drive passed the quick WD diagnostic and is currently being precleared. I'll check the smart report when its done and go from there. Thanks again for your assistance. Cheers
