Apologies for the late response (I have been looking at the bug report and trying to figure out just what's going on, though) For a more immediate solution: you can force run a backing device when the cache set isn't available. If you were using it in writeback mode and there was dirty data in the cache there's going to be data corruption, but IME ext4 fsck can do wonders so it shouldn't be a total loss: echo 1 > /sys/block/sda/sda3/bcache/run (for e.g. sda3) -- 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
