It's not like you're going to miss the extra 64KB. Or, better yet, shrink it by 1Mb or even 10Mb, whatever, convert to raid, and - the point - resize it to the max size of the raid device (ie, don't give "size" argument to resize2fs). This way, you will be both safe and will use 100% of the available size. /mjt - To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
