out of which only 100 gb is used by 2 logical volumes /dev/vg00/lvol0 and /dev/vg00/lvol0 respectively (both are 50 gb each).
Whenever i use vgreduce command to reduce the size of volume group i get below error.
Code:
# vgreduce vg00 -a
Physical volume "/dev/xvdb5" still in use
How can i reduce the volume group size to free up 100 gb?

Greetings Pinga,
as frappa mentionned vgreduce is to remove PVs (which are finally disk devices...), what was your intention? For you still have in that vg 100GB unallocated; is vg00 the one containing your OS?
Vbe the actual problem is this.
I have 200gb of harddisk file attached to this machine(virtual machine). But due to space crunch i have to reduce this 200 gb to 150 gb or less.
How would i go about it? Only 6.7 gb /200 gb is used till now.
if I understood, you'd like to use the remaining space on the PV that is non currently in use by the existing LVs?
Why don't you create new LVs and assign them to some needed mountpoint?
^^No its not the case i want to reduce the size of harddisk (I mean virtual harddisk for e.g vmdk file in vmware ,img file in Oracle VM).
I m using Oracle VM 2.2.
There is one more issue now.
I somehow managed to reduce the size of virtual disk from 200 to 150 but i dont see any changes.
Code:
# fdisk -l
Disk /dev/xvda: 13.3 GB, 13316728320 bytes
255 heads, 63 sectors/track, 1619 cylinders

Disk /dev/xvdb is changed from 161.0 GB from 200GB.
but still vgdisplay is showing 200GB????

If you notice the above output /dev/xvdb5 is showing 200gb but actually it is 150 gb only
The best would be of course to umount the filesystems of vg00 then since you have only one PV, use vgremove to remove the vg group and recreate it again...
You would have to get it to recognize the new size of your virtual PV (never tried in vmware...) that means a pvcreate...
