I do not see any problem with that configuration. LVM is transparent to
the ext2-filesystem above it and AFS doesn't do any nasty things with
the filesystem anymore.

Yes. Shutdown of all afs-related services is recommended

bos -shutdown -all
umount /vicepa
lvresize /dev/$vg/$lv +$numG
e2fsck -f /dev/$vg/$lv
resize2fs /dev/$vg/$lv
mount /vicepa
bos restart -all (or something like that)

Good Luck. In doubt, make a backup before.
