I installed RedHat 9 with LVM, and that works beautifully. I recently
created a new logical volume and installed Gentoo Linux. I can dual boot
into Gentoo and Redhat with out trouble. The swap, /home, and /usr/local
partitions are shared between Gentoo and Redhat.
LVM works without trouble in Redhat, however, I have some problems in
Gentoo. pvscan shows the PV to be inactive, and lvscan gives an error.
The actual logical volumes can be mounted and used without trouble. The
other lv* command appear to work, but lvscan does not. Is this something
to worry about? What can I do to fix this?
Output of pvscan etc is below:
This is in Gentoo:
