環境: Ubuntu 9.10 server

$ sudo apt-get install lvm2

$ sudo pvscan
PV /dev/sdb2   VG VolGroup00   lvm2 [148.94 GB / 32.00 MB free]
Total: 1 [148.94 GB] / in use: 1 [148.94 GB] / in no VG: 0 [0   ]

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

$sudo lvscan
ACTIVE            '/dev/VolGroup00/LogVol00' [146.97 GB] inherit
ACTIVE            '/dev/VolGroup00/LogVol01' [1.94 GB] inherit

ACTIVEになっていればマウントできる．

$ sudo lvscan
inactive          '/dev/VolGroup00/LogVol00' [146.97 GB] inherit
inactive          '/dev/VolGroup00/LogVol01' [1.94 GB] inherit

このように inactive の場合は

$ sudo vgchange -ay VolGroup00
2 logical volume(s) in volume group "VolGroup00" now active

$ lvscan
ACTIVE            '/dev/VolGroup00/LogVol00' [146.97 GB] inherit
ACTIVE            '/dev/VolGroup00/LogVol01' [1.94 GB] inherit

普通にマウントする．

$ sudo mount -t auto /dev/VolGroup00/LogVol00 /mnt/lvm00

$ vgchange -an VolGroup00
0 logical volume(s) in volume group "VolGroup00" now active

$ lvscan
inactive          '/dev/VolGroup00/LogVol00' [146.97 GB] inherit
inactive          '/dev/VolGroup00/LogVol01' [1.94 GB] inherit

複数のLVMが存在し，同じボリューム名のためマウントできない場合は片方のボリューム名を変更する．

$ vgrename VolGroup00 VolNewGroup00
