Hello,

While installing OpenSUSE 10.3 RC1, I used an LVM group on an USB external hard
drive for creating the root partition.
The first part of the setup (until the first reboot) went without problems,
but, after rebooting, the root partition would not be detected any more.

After some troubleshooting, I found out that the script that activates the LVM
group (/boot/62-lvm2.sh) is run BEFORE the USB subsystem had time to finish
detecting all attached devices (especially, but not limited to, when using
external USB hubs).

The way I solved the problem was by inserting a
/bin/sleep 10
line in the /boot/62-lvm2.sh file from the initrd, right before the following
statement:
for vgr in $lvm $vg_root $vg_roots; do
        vgchange -a y $vgr
done

Now, although this solved my particular problem, I think you should consider
the delay (that the USB subsystem introduces while scanning and detecting
devices) in a more general manner (I haven't figured it out when exactly does
the boot process activate the USB subsystem - 04-udev.sh maybe ?) because it
may affect other installation scenarios as well (external USB drive with no
LVM, or with software RAID).

The problem was also present in Beta 3 but I didn't have the time to
troubleshoot.

Cheers,
George Iosif
