David, you were absolutely right. The lilo error was down to the 2.4
kernel not having device mapper built in. Running lilo when running
under 2.6.5 produced no error.
I did update the lvm-common and lvm10 packages to the latest (I'm
running Sid btw). But this produced the same thing (no mounted lvm),
although I've noticed some additional errors during bootup now. Here is
a small bit from /var/log/boot:
...
All modules loaded.
Setting up LVM Volume Groups...
vgscan -- LVM driver/module not loaded?
vgchange -- LVM driver/module not loaded?
...
As far as I know, LVM is built into my kernel. In the menuconfig I
selected to build in the multi device support (didn't bother with RAID
since I dont need it). The section from my .config is as follows:
#
# Multi-device support (RAID and LVM)
#
CONFIG_MD=y
CONFIG_BLK_DEV_MD=m
# CONFIG_MD_LINEAR is not set
# CONFIG_MD_RAID0 is not set
# CONFIG_MD_RAID1 is not set
# CONFIG_MD_RAID5 is not set
# CONFIG_MD_RAID6 is not set
# CONFIG_MD_MULTIPATH is not set
CONFIG_BLK_DEV_DM=y
# CONFIG_DM_CRYPT is not set
Is this enough or am I missing something?
Regards,
Andrew
