[linux-lvm] successes & resizing


i resolved the problem i posted about last week:  unable to mount root
device in trying to set up lvmroot using a bootable real ext2 partition
and initrd. they key (and this maybe a FAQ but i didn't see it) was
getting my scsi driver loaded into the initrd.  this was as simple as
unzipping the initrd-lvm-2.4.3.gz file, mouting on the loopback.  copying
the scsi module into place in /lib/modules and adding a modprobe to
linuxrc.  after that, all was good.  this may be worth documenting
somewhere (i was considering taking the existing info about lvm root and
doing a HOWTO given that i've set it up 5 or 8 times in the last two

i have a separate question about ext2 resizing on a separate system:  when
i try to resize the root (using the ext2online resize patch to 2.4.3) i
