I have accidentally configured my SSD as a backing device instead of a caching device. Simply trying either one of the following:
sudo make-bcache -C /dev/sdb1 sudo make-bcache -C /dev/sdb
Gives the errors:
Can't open dev /dev/sdb1: Device or resource busy Can't open dev /dev/sdb: Device or resource busy
How does one rectify a situation like this?
