I'm moving my data from the old server, kernel 2.4 and lvm1. To a new server, kernel 2.6 and lvm2. I thought I'd start by removing hdd1. It's 80gb and I have about 111gb free.

pvmove --test /dev/hdd1
pvmove -- couldn't find source physical volume "/dev/hdd1" in volume group "vg_main"

I have /dev/vg_main/storagelv as the drive I wanna take the space from.

pvdisplay /dev/hdd1 works, total pe's 3575
would the best way of doing this be:
lvreduce -l-3575 /dev/vg_main/storagelv
resize_reiserfs /dev/vg_main/storagelv (I think reiserfs can do online resizing?) then umount /mnt/storage
pvmove /dev/hdd1
vgreduce /dev/hdd1
?

I wanna make damn sure I get this right before I do it.

i'd reduce the fs _BEFORE_ shrinking the underlying device.
