Below is part of $ lsblk return:
----------------------------------------- sdb sdb 8:16 ├─sdb1 sdb1 8:17 btrfs poppy-root └─sdb2 sdb2 8:18 --------------------------------------------------
/dev/sdb2 has no filesystem yet, and is not mounted anywhere.
Now running this command: ------------------------------------------------------ # make-bcache --block 4k --bucket 2M -B /dev/sdd4 -C /dev/sdb2 --discard Can't open dev /dev/sdb2: Device or resource busy -----------------------------------------------------------
I can't find any reason for /dev/sdb2 to be busy.
looking more carefully in /dev, I couldn't find any mapper or loop device be the culprite Running # mount | column -t did not show the device anywhere
Thank you for hint.
