[linux-lvm] lvreduce



I ran across this today, and wanted some clarification if I could. I am
running kernel 2.4.21 and lvm 1.0.7.

I needed to resize a partition, reducing it by 1GB. As I have done in the
past, went into single user mode, umounted the partition did a
resize_reiserfs -s-1GB /dev/vg00/var

This went fine, then I tried to reduce the size of the lv, using 
lvreduce -L-1G /dev/vg00/var

lvreduce -- WARNING: Reducing active logical volume to 1 GB
lvreduce -- THIS MAY DESTROY YOUR DATA (filesystem etc.)
lvreduce -- do you really want to reduce "/dev/vg00/var"? [y/n]:

Isn't the -L-1G option for lvreduce supposed to reduce the lv _by_ the
requested amount rather than _to_ that size? If specify -L1G, that should
be an absolute value rather than a relative value.

Am I missing something here? Would this be better addressed to the Debian
maintainer for the lvm tools?

Thanks,
