I don't seem to be able to format a brand new NVME SSD drive to use as a cache drive. I check that I want to format the drive and click format it then acts like it is formatting the drive.

I'm getting these errors:

Sep 17 22:57:43 Dorothy emhttpd: writing MBR on disk (nvme0n1) with partition 1 offset 64, erased: 0
Sep 17 22:57:43 Dorothy kernel: print_req_error: I/O error, dev nvme0n1, sector 0

Sep 17 22:57:43 Dorothy emhttpd: shcmd (1526): mkdir -p /mnt/cache
Sep 17 22:57:43 Dorothy emhttpd: /mnt/cache mount error: Unsupported partition layout

Could I have gotten a bad drive/adapter for it?

Thanks,

Looks like a device problem, please post the diagnostics: Tools -> Diagnostics

Try formatting it in a different PC and/or with a different OS, but looks like a device problem.

Put it into my Windows Desktop and was able to format it. But still getting the same issue when its put back into the server.

See if you can format it manually in Unraid, just to confirm if it's a Linux or Unraid issue.

 

First wipe it with blkdiscard then partition and format, I can post the commands if you don't know how to.

I was able to figure this out. Looked into my motherboard PCIE slots and found out I was using a gen2 slot instead of a gen 3. Appreciate you trying to help!

Thanks for posting back, weird that would cause the format to fail.
