[gentoo-amd64] lvm2 resize and loading

[Beso]

i have some little issues with my lvm volumes. i passed today to lvm2 and i
had some problems at first with their loading (i had to put /sin/vgchange -a
y into the modules service which started at boot) but that let's say it's
resolved. i've later seen that i have a small partition with only 1gb of
free space, and i'd like to resize it. i have the lvm filled but i have
another partition that is empty. so i can resize it down and then resize the
other. the filesystem i use is reiserfs v3.6 with r5 hash and ordered mode.
i have the tail option enabled also.
is there a way to fix the first problem and to resize the partitions in a
safe way?!
