Unraid 6.9.2: help needed - drives keep getting write errors

[jokerjack666]

Hi - I have recently swapped out a marvel controller as kept getting drive errors and thought it was that as it isn't supported.  I am still getting drive errors but nothing showing up in SMART on any of the drives.  I am having to drop out drives from the array and re-add a lot now, please help as its driving me crazy!

This is happening with multiple devices:

 

Jul 26 07:55:05 Tower kernel: sd 10:0:3:0: Power-on or device reset occurred
...
Jul 26 07:55:24 Tower kernel: sd 10:0:5:0: Power-on or device reset occurred
...
Jul 26 07:55:41 Tower kernel: sd 10:0:4:0: Power-on or device reset occurred

 

This is usually a connection/power problem.

Thanks for the response, I have another power supply will swap out and see what happens.

You should check data and power cables on both sides and also limit the use of power splitters.

Still getting drive failures, I have played around and changed cables, psu etc but still getting errors.  They always seem to be disks that are running on the controller not direct on the motherboard.  Do I need to do anything in the bios to that pciex16 channel? I have never hooked up this sever to a monitor so everything is default.  Motherboard is strix 8450-f

Usually not, try the controller in a different PCIe slot if available, if that doesn't help try a different controller.
