On my simple test with ubuntu precise, loop-mounted ext4, 8k hardlinks: $ sudo btrfs-convert /dev/loop0 creating btrfs metadata. $ echo $? 139 so no useful error message, but it doesn't crash. And when mounted the device still shows ext4. A successful conversionn would look like this: $ sudo btrfs-convert /dev/loop1 creating btrfs metadata. creating ext2fs image file. cleaning up system chunk. conversion complete. -- Fajar -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
