unRAID red balling perfectly good hard drive

Hi all, I'm experiencing an issue with my unRAID array. For some reason that I cannot identify, my parity and occasionally a data disk is being red balled as failed when there's no smart errors. My log is showing errors, but I can't narrow down what's wrong.

 

Please see my attached unraid-diagnostics report.

 

Thank you to whoever can assist with this problem.

I agree. I at least want to know what's going on and which drive is an issue. I've already reseated all my drives with new sata cables. Can it be a power issue? My PSU is a 430W I believe.

 

Here's my specs:

 

M/B: ASRock - B85 Killer

CPU: Intel® Xeon® CPU E3-1241 v3 @ 3.50GHz

HVM: Enabled

IOMMU: Disabled

Cache: 256 kB, 1024 kB, 8192 kB

Memory: 14 GB (max. installable capacity 32 GB)

01:00.0 Serial Attached SCSI controller [0107]: LSI Logic / Symbios Logic SAS2008 PCI-Express Fusion-MPT SAS-2 [Falcon] [1000:0072] (rev 03)

Though there are no pending sectors this looks like a disk error, this is disk9 (WDC_WD20EFRX-68EUZN0_WD-WCC4M0NV1LTS)

This disk has been causing a few issues for me. Randomly, unRAID will report Errors on my dashboard but not redball the disk.

 

What's strange is that my parity is getting disabled randomly as well. I've been dealing with this for the past month and can't figure out which disk is the issue, or if something else is.

 

Right now, I'm rebuilding my parity and seeing what logs I can pull up. Attached is my latest syslogs. Ton's of errors and I can't make out what it is.

Thanks, I'm going to RMA the drive and see if there's still problems.

 

Does anything seem to indicate a PSU issue or LSI card problem?
