I thought you were growing /tmp.... But, now that you mention it, I didn't notice that you were unmounting and fscking /var before lvextend and resize2fs. Generally growing should work with just lvextend and resize2fs, because you are only tacking things on to the end of the filesystem, not touching most of the existing data structures. Shrinking is the more interesting challenge, because you are looking at the potential of "moving" data. While this is handled just fine by resize2fs, it is "strongly" recommended to e2fsck beforehand to ensure you are starting from "stable structures". So shrinking is normally: umount, e2fsck, resize2fs, lvreduce, and mount. The danger is that lvreduce has no knowledge of the filesystem which resides on top of it, so is perfectly happy with shrinking into "live" structures. That's why I was concerned with you using an "absolute" number for resize2fs and a relative number for lvreduce earlier. To easy to slip up and lvreduce into the filesystem.
