It demands -t.

[root at cod ~]# mount  /dev/VolGroup00/LogVol01 test2
/dev/mapper/VolGroup00-LogVol01 looks like swapspace - not mounted
mount: you must specify the filesystem type
[root at cod ~]# mount  -t lvm2 /dev/VolGroup00/LogVol01 test2
mount: unknown filesystem type 'lvm2'
[root at cod ~]# mount  -t ext2 /dev/VolGroup00/LogVol01 test2
mount: /dev/mapper/VolGroup00-LogVol01 already mounted or test2 busy
[root at cod ~]# mkdir test4
[root at cod ~]# mount  -t ext2 /dev/VolGroup00/LogVol01 test4
mount: /dev/mapper/VolGroup00-LogVol01 already mounted or test4 busy
