[WBEL-users] Howto shrink LVM Logical Volume in WBEL4?

[Eric B.]

Hi,

I went through the trouble of installing / using LVM on my system as I read 
that it allows you to easily shrink / grow your logical partitions without 
having to deal with new mounting points, etc...  But I find myself in a 
quandry.  I need to shrink down on of the Ext3 partitions on a Logical 
Volume on WBEL4, and can't seem to figure out how.

According to RH docs, ext2online only works for expanding LogVols, not 
reducing them.

I have search around, but can't seem to find anything that will safely let 
me reduce it.  I am more than happy to reduce the LogVol offline (ie: 
partition unmounted), but even at that, I am failing to figure out how.  I 
read the pages for lvreduce, but that seems to indicate that I risk losing 
data if I don't resize the filesystem first.

Does anyone have an idea how/what I can do to accomplish this?

Thanks!

Eric
