Hi,

 

First time unraid user, I bought a refurbished server with some disk 3 HHD and 1 SSD (I think it was windows installed). I configured the array and one cache pool, the HHD were able to format, but the SSD is giving the "cache Unmountable: Unsupported or no file system" error. I tried to find a solution but no luck, can someone help me? Diagnostics zip attached, and a screenshot of the configurations.

 

Thanks in advance

Stop the array, click on the cache device, then "Erase Pool", start the array and re-format, that should do it.

Thanks @JorgeB, tried that but still no working, more logs attached

It's still being detected with a FAT filesystem, post the output from:

wipefs /dev/nvme0n1p1

and

blkid

 

Thanks for the follow-up

root@LegoServer:~# wipefs /dev/nvme0n1p1
wipefs: error: /dev/nvme0n1p1: probing initialization failed: No such file or directory
root@LegoServer:~# blkid
/dev/sda1: LABEL_FATBOOT="UNRAID" LABEL="UNRAID" UUID="1DFE-2857" BLOCK_SIZE="512" TYPE="vfat" PARTUUID="8e75c43b-01"

/dev/loop0: BLOCK_SIZE="131072" TYPE="squashfs"

/dev/md2p1: UUID="f7ebcec3-4a45-4680-947f-2f555e63d689" BLOCK_SIZE="512" TYPE="xfs"

 

Now the output from:

wipefs /dev/nvme0n1

 

Thanks again, i got no output

The device looks clean, now click on the 1st pool device, then "remove pool", then back on main add a new pool with the same name, and try again, it should now work.

Yes it worked now, Thanks a lot @JorgeB
