yitzi Posted September 30, 2016 Share Posted September 30, 2016 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. unraid-diagnostics-20160930-1002.zip Quote Link to comment
trurl Posted September 30, 2016 Share Posted September 30, 2016 Most frequent problem is bad connection. Check SATA and power both ends. If the 2 problems are on the same controller you might consider that as well, perhaps reseating the card. Maybe some more info about your hardware. Quote Link to comment
Rebel Posted September 30, 2016 Share Posted September 30, 2016 The logs will say why it's failing, sometimes you can get data errors that can flag the disk that the drives own smart doesn't alarm out on. Can you pull the disk and run something like spinrite on it? Quote Link to comment

yitzi Posted September 30, 2016 Author Share Posted September 30, 2016 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) Quote Link to comment
trurl Posted September 30, 2016 Share Posted September 30, 2016 What is the exact model of your power supply? Quote Link to comment
yitzi Posted September 30, 2016 Author Share Posted September 30, 2016 Confirmed 430w after looking through my purchases. It's a CORSAIR CX series CX430 Quote Link to comment
JorgeB Posted September 30, 2016 Share Posted September 30, 2016 Though there are no pending sectors this looks like a disk error, this is disk9 (WDC_WD20EFRX-68EUZN0_WD-WCC4M0NV1LTS) Sep 30 09:55:22 unRAID kernel: ata2.00: failed command: READ DMA EXT Sep 30 09:55:22 unRAID kernel: ata2.00: cmd 25/00:08:b0:22:38/00:00:3a:00:00/e0 tag 12 dma 4096 in Sep 30 09:55:22 unRAID kernel: res 51/40:08:b0:22:38/00:00:3a:00:00/e0 Emask 0x9 (media error) Sep 30 09:55:22 unRAID kernel: ata2.00: status: { DRDY ERR } Sep 30 09:55:22 unRAID kernel: ata2.00: error: { UNC } Quote Link to comment
yitzi Posted September 30, 2016 Author Share Posted September 30, 2016 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. syslog.txt Quote Link to comment
Rebel Posted September 30, 2016 Share Posted September 30, 2016 True but then you will know for sure if your disk actually has a problem or if it's controller / cable / 1000 other issues. Quote Link to comment

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