Ok. I ran "mount -o remount,rw/" and I got fix /etc/fstab.
The output of my mkinitrd command with -v option was:
Using modules: ./kernel/drivers/scsi/scsi_mod.o
./kernel/drivers/scsi/sd_mod.o ./kernel/drivers/scsi/aic7xxx/aic7xxx.o
./kernel/drivers/scsi/ips.o ./kernel/drivers/md/lvm-mod.o

My /etc/lilo.conf is:

label=lvm
initrd=/boot/initrd-lvm-2.4.18-3.img
read-only
root=/dev/rootvg/root
append="ramdisk_size=8192"
I have a initrd directory under /mnt mount point (/dev/rootvg/root)
How can I check that linuxrc in the ramdisk initrd-lvm-2.4.18-3.img contains
something like this:
echo "Loading jbd module"
insmod /lib/jbd.o
echo "Loading ext3 module"
insmod /lib/ext3.o
echo "Loading lvm-mod module"
insmod /lib/lvm-mod.o
echo "Mounting /proc filesystem"
mount -t proc /proc /proc
echo "Running vgscan"
vgscan
echo "Running vgchange -a y"
vgchange -a y
echo Creating root device
mkrootdev /dev/root
echo 0x0100 > /proc/sys/kernel/real-root-dev
echo Mounting root filesystem
mount --ro -t ext3 /dev/root /sysroot
umount /proc
pivot_root /sysroot /sysroot/initrd
