Depending on the performance impact on your particular SSD, you could also try enabling TRIM in bcache which should reduce the need for over provisioning by making sure the SSD knows which blocks it can erase in the background. It would be nice if bcache supported a manual TRIM like fstrim works for filesystems so if you have an SSD whose performance precludes real time TRIM you could schedule a daily or weekly batch TRIM to tune things up. -- 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
