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?
Hi
Use the --wipe-bcache option on the device. I would recommend switching to root user rather than using sudo for things like this…
Thanks, I was looking for something like that. I also followed your device on going root. Unfortunately I am still getting the device or resource busy errors, any ideas?
PS. I did not actually mount any caching device to this drive or do anything to it other than create it as a backing device, I immediately stopped after realizing my mistake.

Hi
OK, so /dev/sdb is just a device by itself?
If it is,run very carefully the command wipefs -a on the partition then
the device and it should then be fine to create as a cache.

Yes, /dev/sdb is a SDD with nothing on it. I tried wipefs -a for /dev/sdb1 and /dev/sdb but am getting “wipefs: error: /dev/sdb: probing initialization failed: Device or resource busy”.

Hi
Have you rebooted the system, sounds like something still hanging on to
it down in /sys/fs.
Then try the --wipe-bcache option.
