OK, I have done the experimentation and everything is now clear and fixed. The /sys/block/bcache0/bcache/state was 'none'. So I did 'make-bcache -C /dev/sda8' I did 'echo <UID> >/sys/block/bcache0/bcache/attach' And I have /sys/block/bcache0/bcache/state is 'clean'. So I'd say that this is what they would call 'cool'. Complete SSD failure is easy to fix and did not cause any collateral damage. -- To unsubscribe from this list: send the line "unsubscribe linux-bcache" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
