I will investigate that further... May I make one more comment that may
help me solve this? Quick note, since the last post I wiped the test
server and re-installed, just in case I had foobar'ed something along
the way.
I have made a backup of '/' (from '/dev/vg0/root') to the backup drive
(/dev/sdd1) and edited '/etc/fstab', '/etc/mtab' and deleted
'/etc/blkid.tab' (which, if I understand is just a cache). I did this on
both the '/' (/dev/vg0/root and /dev/sdd1) while under the Linux Rescue
disk (Fedora Core 1 install in 'linux rescue') and finally I updated
'/boot/grub/grub.conf' on both partitions as well to contain entries
pointing '/' to '/dev/sdd1'. When I reboot (before converting the LVM LV
to ReiserFS) and choose to boot into '/dev/sdd1' as root it -seems- to
work. When I type:
# df
It shows '/' to be '/dev/sdd'. Now to verify this I did:
# cd /
# touch test.txt
# mkdir vg0
# mount /dev/vg0/root /vg0
I then checked to see if the 'test.txt' file was there, and it was. How
the heck can the original settings for '/dev/vg0/root' be -SO-
persistent that even 'df' thinks that the wrong partition is mounted?!?
Where are these settings stored?
Side note: When I boot again off the rescue disk and run the same test
(with '/dev/sdd1' mounted as '/') then it is fine, there '/' really is
'/dev/sdd1'...)
Anyway, I am off to try converting again now that I know to try passing
"init=reiserfs" in grub (will it work though?... Off to see!)
Thank you for being so helpful and patient while I pound my head through
this!
