btrfs resizing (like resize2fs) does not manipulate the size of partitions. First, you need to expand the partition using fdisk or gparted. Afterwards you can use "btrfs filesystem resize max ~/.wine/drive_c" to grow the filesystem to the size of the partition. -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
