有關於LVM的問題 - Linux

各位前輩好呀，我的問題如下，我貼執行的結果好了：

[root@localhost ~]# mkfs -t ext3 /dev/VolGroup00/LogVol01
mke2fs 1.39 (29-May-2006)
/dev/VolGroup00/LogVol01 is mounted; will not make a filesystem here!
##到底是誰mount了他呢？
=======================================================================
[root@localhost ~]# umount /dev/VolGroup00/LogVol01
umount: /dev/VolGroup00/LogVol01: not mounted
又說沒mount.....XD..
========================================================================

抱歉貼了一堆，我要問的是LogVol01到底在哪？我想要把他合併到LogVol00，要怎麼做呢？
謝謝
