Formatting seems to work, and once I do this: echo /dev/sdd1 > /sys/fs/bcache/register echo /dev/nvme0n1 > /sys/fs/bcache/register echo 1 > /sys/fs/bcache/<set-uuid>/blockdev_volume_create a /dev/bcache0 has been created. However, if I try to mount it: mount -t bcache /dev/bcache0 /mnt it says: mount: No such file or directory with a return code of 32, which is documented as "mount failure". At this point I reach the limit of my current understanding, but would like to understand more.
