Hi, 

Can anyone help with the issue in the title. It seems my Unraid server is plagued with this specific issue that I can't seem to resolve. This issue seems to offline a disk and forces the disk to be emulated. It seems even with a new disk I'm encountering the same issues. 

I've attached the logs if anyone wants to have a pop at it. 

Effectively hardware wise so far, I've done the following. 

Replaced the SAS to SATA cables. 
Replaced the HBA cards. 
Flashed HBA firmware.
Replaced HDD's

Any advise will be welcomed. 

Thanks.

I should also note I currently have a this drive outside of the array, it's not been added back into it yet. But I have been running pre-clears on it so check it. The drive is effectively a few weeks old. (If it makes any difference).

Disks keep being re-detected, can you try connecting this disk to onboard SATA instead?

Hello @JorgeB, thank you for your advice. Can you explain how this can happen? I had the same error and followed your recommendation. It actually helped. After a restart it worked again. With a second hard disk, it also worked without replugging, but it took several restarts.

 

Described in more detail:
I have various error messages from various hard disks and am looking for the cause (cables replaced, raid controller replaced, mainboard and CPU to follow). The hard disk in question had reported such errors in the dashboard before it failed.

Those are just from a few minutes after a reboot, don't see any disk errors, post new one if they happen again.
