LVM2 volume group not seen after FC4 install
I have a Intel Celeron system currently running Fedora Core 3. I have 2 internal hard drives: hda has swap, /boot, and an LVM1 volume group with 2 logical partitions. FC3 is installed on one of these partitions (/dev/mapper/rootvg-RootVol01). The other disk, hdb, belongs to an LVM2 volume group and contains all my data. Things have been running quite well under FC3, but I wanted to move to FC4.
After installing FC4 onto the 2nd LVM partition on hda (/dev/mapper/rootvg-RootVol02), I can't see the LVM2 volume group at all. vgscan doesn't even show it. Can anybody help me? I'm not even sure how to double check that my FC4 kernel has LVM2 support.
