Adding net cache device to existing bcache
Hello,
I'm trying to add new cache device to an existing bcache, but unsuccessfully... I thought it should as simple as formating the new cache device (make-bcache) and then attaching it to an existing bcache device. However, this procedure won't work.
Is there any useful howto or another info about this subject.
Regards,
Vlad.

After I issue "make-bcache --cache /dev/sdf3" instantly the new bcache without backing device is registered. This could be fixed by echoing to /sys/fs/bcache/<NEW_DEV_UUID>/stop. But I still can't attach the new device by doing "echo UUID >/sys/block/bcache0/bcache/attach". I've tried to use "make-bcache --cset-uuid <EXISTING_UUID> --cache --wipe-bcache /dev/sdf3", but kernel complains that the device already exists.
