[lug] mount: unknown filesystem type 'lvm2pv'

[Bill Thoen]

/mnt/d appears to be clear. I don't know anything about lvs, so maybe 
that's the problem. Here's what I've tried followed by some system info:

# cd /dev/VolGroup01
# ls
LogVol00  LogVol01
# mount /dev/VolGroup01/LogVol01 /mnt/d
/dev/mapper/VolGroup01-LogVol01 looks like swapspace - not mounted
mount: you must specify the filesystem type
# mount -t ext3 /dev/VolGroup01/LogVol01 /mnt/d
mount: /dev/mapper/VolGroup01-LogVol01 already mounted or /mnt/d busy
# mount -t lvm2 /dev/VolGroup01/LogVol01 /mnt/d
mount: unknown filesystem type 'lvm2'


# vgscan -v

  Reading all physical volumes.  This may take a while...
  Found volume group "VolGroup00" using metadata type lvm2
  Found volume group "VolGroup01" using metadata type lvm2

# fdisk -l
