I still get the same warning for a multi-device setup (besides some different address offsets) followed by [ 196.220085] bcache: bch_open_as_blockdevs() register_cache_set err insufficient devices [ 196.259971] bcache (936fcb06-4a1a-4219-a6ff-eca785c178a0): stopped printed after `sudo mount -t bcache [partition device file] [mountpoint]` (e.g. `sudo mount -t bcache /dev/sdb7 /mnt/data`) after creating a bcachefs with `sudo bcache format /dev/sda1 /dev/sdb7`. I don't get the warning if I format only one device and mount it. I'm not really sure if that's sufficient for a multi-device setup since I only found https://bcache.evilpiepirate.org/Bcachefs/ explaining a single partition setup and there's a difference between commands explained in `man bcache` and `bcache -h` and `bcache -h` isn't sufficiently helpful to work with the command. Are you looking for quite naive end-user testers annoying you about every minor issue in the documentation and command feedback or isn't bcachefs ready for that yet? -Kalle
