Try to mount another hard disk in Fedora 9. One of the partitions is in LVM2 format and cannot be directly: "mount/dev/sdb3/mnt/sdb3 ", A weekly discount was made to find the Mount method. The record is as follows for emergency purposes.

1. pvs

[Root @ localhost yuanbor] #/sbin/pvs
WARNING: Duplicate VG name VolGroup00: Existing tWwhxK-0M8r-sqhQ-VW7m-0BYv-BPkO-pgBRM8 (created here) takes precedence over 7kU450-LaPn-afEa-iWGw-xiqD-Tmwe-ohpL3f
Pv vg Fmt Attr PSize PFree
/Dev/sda2 VolGroup00 lvm2 a-33.97G 32.00 M
/Dev/sdb3 VolGroup00 lvm2 a-36.78G 32.00 M

This is miserable. The two VG names are duplicated. Modify the name of the second VG.

2. vgrename

[Root @ localhost yuanbor] #/sbin/vgrename 7kU450-LaPn-afEa-iWGw-xiqD-Tmwe-ohpL3f/dev/VolGroup01
WARNING: Duplicate VG name VolGroup00: Existing tWwhxK-0M8r-sqhQ-VW7m-0BYv-BPkO-pgBRM8 (created here) takes precedence over 7kU450-LaPn-afEa-iWGw-xiqD-Tmwe-ohpL3f
Volume group "VolGroup00" successfully renamed to "VolGroup01"

[Root @ localhost yuanbor] #/sbin/pvs
Pv vg Fmt Attr PSize PFree
/Dev/sda2 VolGroup00 lvm2 a-33.97G 32.00 M
/Dev/sdb3 VolGroup01 lvm2. a-36.78G 32.00 M

3. lvscan

[Root @ localhost sdb3] #/sbin/lvscan
Inactive '/dev/VolGroup01/logvol00' [34.81 GB] inherit
Inactive '/dev/VolGroup01/LogVol01' [1.94 GB] inherit
ACTIVE '/dev/VolGroup00/logvol00' [32.00 GB] inherit
ACTIVE '/dev/VolGroup00/logvol01' [1.94 GB] inherit

The modified VolGroup01 is inactive.

4. vgchange

[Root @ localhost sdb3] #/sbin/vgchange-ay/dev/VolGroup01
2 logical volume (s) in volume group "VolGroup01" now active

[Root @ localhost mnt] #/sbin/lvscan
ACTIVE '/dev/VolGroup01/logvol00' [34.81 GB] inherit
ACTIVE '/dev/VolGroup01/logvol01' [1.94 GB] inherit
ACTIVE '/dev/VolGroup00/logvol00' [32.00 GB] inherit
ACTIVE '/dev/VolGroup00/logvol01' [1.94 GB] inherit

Now you can mount it.

5. mount

[Root @ localhost mnt] # mount/dev/VolGroup01/LogVol00/mnt/sdb3
