May be your problem?
$ cat /proc/mounts

But look at this.
$ mount
/dev/mapper/VolGroup00-LogVol00 on / type ext3 (rw)
proc on /proc type proc (rw)
sysfs on /sys type sysfs (rw)
devpts on /dev/pts type devpts (rw,gid=5,mode=620)
/dev/sdb1 on /boot type ext3 (rw)
tmpfs on /dev/shm type tmpfs (rw)
none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw)
sunrpc on /var/lib/nfs/rpc_pipefs type rpc_pipefs (rw)
Note that the root file system is not mounted by the kernel using the
LVM name, but rootfs. But mount shows (it uses /etc/mtab) the LVM name.
Maybe using the mount command, or a grep on etc/mtab, will show that the
volume is mounted somewhere.
Another possibility is to use lsof (see the man page, maybe the +D
parameter will be useful) or maybe fuser (see the man page again). Keep
in mind that the volume maybe be accessed with names other than VolG*.
E.g.
# find /dev -exec ls -dl {} \;|grep 253
brw------- 1 root root 253, 0 Aug 23 07:28 /dev/root
brw-rw---- 1 root disk 253, 1 Aug 23
07:28 /dev/mapper/VolGroup00-LogVol01
brw-rw---- 1 root disk 253, 0 Aug 23
07:28 /dev/mapper/VolGroup00-LogVol00
$ ls -l /dev/mapper/
total 0
crw------- 1 root root 10, 63 Aug 23 07:28 control
brw-rw---- 1 root disk 253, 0 Aug 23 07:28 VolGroup00-LogVol00
brw-rw---- 1 root disk 253, 1 Aug 23 07:28 VolGroup00-LogVol01
$ ls -ld /dev/Vol*
drwx------ 2 root root 80 Aug 23 07:28 /dev/VolGroup00
