I'm trying to set up bcache drives on a Ubuntu 13.10 system. When I get to the point of registering the devices, using the command "echo /dev/sd1 > /sys/fs/bcache/register", i'm getting the error: bash: echo: write error: Invalid argument I've googled the heck out of this an am coming up with nothing. Has anyone experienced this? If so, have you found a solution for it? Thank you so much.
