Hello,

 

I've noticed my unraid disk log fill up with these messages that report sata link speed change:

  

Feb 14 23:55:31 DataServer kernel: ata2.00: configured for UDMA/133
Feb 14 23:56:20 DataServer kernel: ata2: SATA link up 6.0 Gbps (SStatus 133 SControl 300)
Feb 14 23:56:20 DataServer kernel: ata2.00: configured for UDMA/133
Feb 14 23:57:56 DataServer kernel: ata2: SATA link up 6.0 Gbps (SStatus 133 SControl 300)
Feb 14 23:57:56 DataServer kernel: ata2.00: configured for UDMA/133
Feb 14 23:58:10 DataServer kernel: ata2: limiting SATA link speed to 3.0 Gbps
Feb 14 23:58:11 DataServer kernel: ata2: SATA link up 3.0 Gbps (SStatus 123 SControl 320)
Feb 14 23:58:11 DataServer kernel: ata2.00: configured for UDMA/133
Feb 15 00:04:56 DataServer kernel: ata2: SATA link up 3.0 Gbps (SStatus 123 SControl 320)
Feb 15 00:04:56 DataServer kernel: ata2.00: configured for UDMA/133

 

Is this something to be concerned about? These messages seem to have appeared right after I changed my hardware. Current specs:

  

Model: Custom
M/B: Gigabyte Technology Co., Ltd. Z87X-D3H-CF Version To be filled by O.E.M. - s/n: To be filled by O.E.M.
BIOS: American Megatrends Inc. Version F8. Dated: 01/17/2014
CPU: Intel® Core™ i7-4770K CPU @ 3.50GHz
HVM: Enabled
IOMMU: Disabled
Cache: 256 KiB, 1 MB, 8 MB
Memory: 16 GiB DDR3 (max. installable capacity 32 GiB)

 

I ran unraid for ~1 month previously on an older AMD phenom II x4 965 with GA-78LMT-USB3 (rev. 4.1) mobo and the log was nice and clean compared to a spam of these ata messages on the current system...

Some more errors this time in red... 

 

Is this something that needs immediate action? I was doing a parity check when these new ones appeared. I'd have more time to play around with the controller on weekend... Parity check returned 0 errors.

I changed my SATA controller mode from AHCI to IDE in mobo BIOS and so far the 2 main drives are stable without any weird messages. Speed for the parity check is identical so I will probably keep it this way. However I found some weird warnings in my smaller 1 TB hdd:

What are UDP packet messages appearing on one of my drives?

Those have nothing to do with drives, and if not needed you can disable WSD (settings -> SMB) to fix that.

I'm more curious to the cause for this. Why did the messages appear on only one of my drives log? SMB settings seem to be global for my entire server... What makes this drive special?

So if I connect my drive to 5th sata port instead of the 4th these messages will go away? Wow that some interesting behavior...

Probably not, the messages will just show up in whichever drive gets assigned to the sdd device. Unraid assigns drives based on when in the boot process they are detected, so the sd? can change randomly. That's why all drive identification for array slots is based on serial numbers.

 

I think you are missing the point though, the messages are simply a list of the lines in the syslog that reference a specific sd? designation, and because wsdd contains the letters sdd in order, it's being added to the list for that device.
