Hi Everyone,

 

A few weeks ago, I noticed that my docker containers disappeared. 

 

I was planning on doing an upgrade of my server to a new motherboard and CPU, so I decided I would investigate when moving the hard drives and SSD to the new server.

 

I noticed scorch marks on the SSD, the cable was secure, so not sure what happened. The SSD may still work, but wasn't able to get it to appear after plugging it in (it's over 10 years old).

 

The new motherboard had a slot for an NVME drive, so I added an NVME drive for my new cache drive. This NVME drive was previously used for my laptop, and had Windows installed on it. When I tried to add the NVME drive as the new cache, Unraid told me that I wasn't able to boot with it.

 

While troubleshooting, I found someone recommended a new config, while preserving the previous drives. I did a new config, and my drives completed a new rebuilt parity, however, the new cache drive wouldn't mount and had an error of "Cache drive unmountable: Wrong or no file system".

 

I had read some forum posts that suggested it might need to be formatted in Windows due to Unraid only seeing the recovery partition and not the whole drive. Note, that Unraid's formatting wasn't working.

 

After formatting (to I believe NTFS), the drive still won't mount as my cache and now shows "Unmountable: no file system". I have tried a few rescue commands and reboots. The NVME drive works on Windows, just can't get it to work in Unraid.

 

I have turned off docker, and VM Manager. 

 

Thank you for any help you can provide.

This is a bug, it's trying to format it FAT, stop the array, click on the cache device, change the fs to the one you want to use, start the array, format.
