Hi, Here is what I did: # make-bcache -C /dev/sdb1 # echo "UUID" > /sys/block/bcache0/bcache/attach -------------------------------------- $ lsblk -o ....................... sdb sdb └─sdb1 sdb1 bcache └─bcache0 bcache0 -------------------------------- # mkfs.btrfs -L poppy-root /dev/sdb1 /dev/sdb1 appears to contain an existing filesystem (bcache). Error: Use the -f option to force overwrite. Please may you tell what is wrong and how can I make btrfs on bcached partition?
