    Because it's a different problem, you have an actual missing device:

    Apr 18 18:05:26 NAS emhttpd: /mnt/cache uuid: c0604d95-a95d-4473-b590-5d657cf45624
    Apr 18 18:05:26 NAS emhttpd: /mnt/cache found: 2
    Apr 18 18:05:26 NAS emhttpd: /mnt/cache extra: 0
    Apr 18 18:05:26 NAS emhttpd: /mnt/cache missing: 0
    Apr 18 18:05:27 NAS emhttpd: /mnt/cache warning, device 2 is missing
    Apr 18 18:05:27 NAS emhttpd: /mnt/cache Label: none  uuid: c0604d95-a95d-4473-b590-5d657cf45624
    Apr 18 18:05:27 NAS emhttpd: /mnt/cache Total devices 3 FS bytes used 429.72GiB
    Apr 18 18:05:27 NAS emhttpd: /mnt/cache devid    1 size 953.87GiB used 698.03GiB path /dev/nvme0n1p1
    Apr 18 18:05:27 NAS emhttpd: /mnt/cache *** Some devices missing
    Apr 18 18:05:27 NAS emhttpd: /mnt/cache mount error: Invalid pool config

     

    No valid btrfs filesystem is being detected on the other NVMe device, and whatever happened it did before the diags posted, since no fs was detected on boot, if the device was wiped with wipefs you should be able to restore it with:

     

    btrfs-select-super -s 1 /dev/nvme1n1p1

     

    If the command completes successfully then you need to reset the pool, to do that unassign all cache devices, start array to make Unraid "forget" current cache config, stop array, reassign all cache devices (there can't be an "All existing data on this device will be OVERWRITTEN when array is Started" warning for any cache device), start array, if it still doesn't mount please start a new thread in the general support forum and post new diags.

     

    As ever... you're a star... Thanks
