Missing disks from cold start but all available after reboot

[jimkuye]

Hi everyone,

 

I have this issue several months ago, it costs me to spend about 5 min to reboot every time I start the server and I really want to fix it today.

 

I have 2 SSD cache drives and 6 hard drives (1 as parity check). Every time I cold start my sever, I will missing my parity disk and one of data disks, other drives are fine. And normally I have to restart my server and everything will become online just fine. I have attached two screenshots with one of them showing more SATA devices is after rebooting and the other one showing fewer SATA devices is from cold start. It seems to be the disks connected to the Marvell SATA controller are missing from the cold start and back online after rebooting. I just want to fix this issue. Other than this, my unraid server serves me very well.

 

The overall hardware specs are:

MB:

ASRockRack C246 WS
American Megatrends Inc., Version P2.20
BIOS dated: Wed 16 Oct 2019 12:00:00 AM CST

CPU:

Intel® Xeon® E-2176G CPU @ 3.70GHz

Memory:

32GB ECC Memory

Unraid:

6.9.2

 

If you guys need any other info, I will upload them ASAP. Thank in advance.

So what is the solution? or any work around? Is that simply Marvel SATA controller is not a good option for unraid hard drives? Or it can be fixed by some update? just saying.

So a new idea just showed up. Is it possible to run a user script, which will automatically restart the server when the parity check hard drive is missing? If so, any recommendation for script writing?

Even if there was a way it wouldn't be a good idea. Any missing disks will likely be out of sync and need rebuild. Fix the hardware problem.
