I am running Unraid 6.7.2. I just installed an Intel 660p 2TB NVMe that I am trying to set up for a cache drive. I have assigned it yet when I try to format it, it always results as a Unmountable: No File System. Have tried with xfs as well btrfs. I have not been able to get the drive to format at all. I don't know where to continue from here. Any and all help is appreciated. Thanks in advance. I have attached a screenshot of the main page as well as my diagnostics.

The syslog shows that you are getting I/O errors on that drive and suggesting a potential controller issue.   It might be worth checking the drive is properly seated.

 

I have one of those drives as my cache drive on my Unraid server so these is no inherent incompatibility with Unraid.

I will try reseating again and see what the outcome is. I have tried 3x and nothing. Could also put into my external enclosure and just make sure disk isn’t defective. Other than, I don’t n ow what else to try 

Thanks itimpi for the help.

 

Ended up swapping with another 660p and it works now. Must of just been a defective drive. Now my issue is after a bit of moving files around, when I try to copy stuff to share, it tells me its write protected. 

 

Update: Spoke to soon. Went to reboot to see if the write protection would 'fix' itself on reboot and the cache drive just disappeared again.
