I am using ext2 file systems though. The default kernel parameter is ramdisk size 4096. I read the messages to mean the ramdisk is not large enough. I fixed it by adding a ramdisk option to the root on lvm entry in lilo.conf so it looked like this:- image=/boot/vmlinuz-2.4.2-2-lvm.1 label=linux-lvm initrd=/boot/initrd_from_lvmcreate_initrd read-only root=/dev/vg00/root ramdisk=5120 Could have up the kernel parameter instead I guess. I have not done testing yet and will give a better account of my problems and solutions later. Since lvm was the only module in the ramdisk it may be that a default ramdisk is not enough. Perhaps we should add a note to the HOW-TO for days like this. JFTR. I'm using RH 7.1 and beta7 LVM. Tom.
