Allora perche':

In home in roby che sarei io utente ho creato la cartella: temporanea

Ottengo

[root a localhost ~]# vgchange -a y VolGroup00
  2 logical volume(s) in volume group "VolGroup00" now active
[root a localhost ~]# mount /dev/VolGoup00/LogVol00 /home/roby/temporanea
mount: you must specify the filesystem type
[root a localhost ~]# mount -t ext3 /dev/VolGoup00/LogVol00 
/home/roby/temporanea
mount: special device /dev/VolGoup00/LogVol00 does not exist
[root a localhost ~]# mount -t ext2 /dev/VolGoup00/LogVol00 
/home/roby/temporanea
mount: special device /dev/VolGoup00/LogVol00 does not exist
[root a localhost ~]#
