Hi there, hoping to get some direction on an issue I'm having. I've had the server unexpectedly reboot twice in the last 5 days. I checked the logs and I am seeing a constant message;

Dec 17 17:31:14 Tower kernel: ata1: SATA link down (SStatus 0 SControl 310)
Dec 17 17:31:15 Tower kernel: ata1: limiting SATA link speed to 1.5 Gbps

I guess I don't know what to make of this. I assume there's a bad sata cable or something? None of my drives are showing CRC errors or any other smart errors according to the dashboard or scrutiny. Any help would be appreciated, thanks.

Unlikely that the SATA errors are related to the reboots, and a server rebooting on its own is almost always a hardware problem, for the SATA issue try replacing the cables for that device.

I just wanted to update this thread in case anyone came across it when searching.

 

I ran into way more problems than I originally reported on. After a reboot the server wouldn't even make it past POST. I thought maybe the memory had went bad. Went through troubleshooting all 8 sticks with not much success. It did boot once and I found roughly 4 drives were not showing up. BAD HBA! LSI 9210-8i wasn't even warm. Tried different pci slots, still nothing. Removed the card, moved drives to second LSI card and attempted booting, still no POST after many attempts. Eventually just transferred all hard drives (12 of them total) and the second LSI card to my old desktop hardware/tower. Works fine now. 

 

I ended up losing at least a LSI 9210-8i, one hard drive, a S2600CP motherboard, not sure on memory sticks or other hardware. Power is provided by a UPS and we didn't have any power events recently so I'm not really sure what happened. So far I have not lost any data, currently in a data rebuild process. Moving to new hardware was painless as I learned unraid is hardware agnostic. 

 

I did have one hard drive go disabled along with the one that failed, luckily I have two parity drives. Hopefully nothing else fails while the data rebuild is happening. New LSI 9305-16i with cables is on order along with a few new 18tb drives.
