rc.sysinit contains the following code to initialize LVM volumes: # LVM initialization if [ -f /etc/lvmtab -a ! -e /proc/lvm ] ; then modprobe lvm-mod >/dev/null 2>&1 fi if [ -e /proc/lvm -a -x /sbin/vgchange -a -f /etc/lvmtab ]; then action $"Setting up Logical Volume Management:" /sbin/vgscan && /sbin/vgchange -a y fi This does _NOT_ work with LVM2's dm-mod which is included in latest RH kernels. I'm using this instead to activate LVM2 partitions: modprobe dm-mod if [ -x /sbin/vgchange -a -f /etc/lvmtab ]; then action $"Setting up Logical Volume Management:" /sbin/vgscan && /sbin/vgchange -a y fi I don't know how to detect wether the modprobe is really needed on the booting system.
This should be fixed as of now....
