It's pretty easy.  Use lvextend to increase the size of the LV, then
run something like resize_reiserfs -f /dev/misc_vg/am_lv, and it'll
just work.  By default resize_reiserfs expands the filesystem to fill
the LV, but you can specify how much to grow the filesystem with -s.

This doesn't work, BTW, for shrinking.  You must unmount the
filesystem to shrink it, then use lvreduce to shrink the LV.
