Recurring erros in logs but array functions fine?

[paulylah]

Hi guys,

 

Trying to troubleshoot something here and im a bit over my head trying to interpret the linux logs. I assume this is a bad drive, cable, or port, but I would greatly appreciate your input before I start juggling stuff around inside the case.

 

The below errors are looping in my syslog. The array operates, and there are no red balls, just one drive flashes grey / green (not sure what this means)

And so on, and so forth. How can i easily identify which drive is playing up? "ata2.01", I assume means controller 2 port 1?

 

Thanks in advance for any inputs.

You'd be better off posting the full syslog, gives a better idea of the overall problem.

CRC errors are usually either a bad SATA cable, OR a cable picking up noise from an adjacent cable.  If you've neatly bundled up all the cables, you've caused it yourself.  Cut the tie-wraps and get some distance between the cables.
