So what I should do is the following:

Lets say the 200GB disc is 6000 PE's big.

e2fsadm -v -l -6076 /dev/vol1/lv_vol

This should make the lvm 200GB smaler.

Then after that I do

pvmove /dev/hdh1

That should then move the content of hdh1 to the other drives ?

Sorry, but I am a bit lost here.

All I want to do is to get the 200GB out of the lvm.

I am running ext2 and there is just that lvm on the system and a small 6GB system disc.

Best regards
