if this were my box (assuming there wasn't a lot of
customization in /etc/ or other system directories),
i'd copy off the entire /etc/ tree and all of the
/home/ tree and verify that i can restore.
then i'd wipe the disk and repartition so's to have
sda1 at maybe 8GB for / ,
sda2 at about 1 GB for /var/ ,
sda3 for 0.5GB swap,
and the rest of the disk (sda4) for /home/ .
the reinstall should set the filesystem appropriately
for the storage area (8GB). i'd try to verify this as
well as ensure that the partitioning-filesystem phase
mapped out bad blocks.
i'd then reinstall and carefully restore any /etc/
customizations and finally copy back my /home/ data.
then i'd go do something fun or relaxing or take a
then i'd reboot and face the music.
i am, of course, eager to read any criticisms, jeers,
there are those who like LVM. i, myself, have some
reservations about LVM, mainly to do with anxieties
about restoring data if something happens to corrupt
the LVM system itself.
