Re: Modify the PE size in 11.31
Hi:
You are looking for the 'vgmodify' command, but it can't modify 'pe_size'.

Re: Modify the PE size in 11.31
Hi,
the pe_size is set during vgcreate ([-s pe_size]), it cannot be changed later.
If you hit the limits, you can increase the max_pe value in 11.23 or 11.31 LVM ver 1.
With LVM ver 2.x you can set a maximum VG size:
"To create a Version 2.0 volume group using 32 MB extents and a maximum size of 1 PB:
# vgcreate -V 2.0 -s 32 -S 1p /dev/vg01 /dev/disk/disk50"
Hope this helps!
Regards
Torsten.

Re: Modify the PE size in 11.31
Hi:
So, if you *must* modify the 'pe-size' of your volume group, simply backup your data; 'vgexport' the volume group [because that's the fastest way to eliminate it]' 'pvcreate' your physical volumes (again); and 'vgcreate' using arguments that create an LVM geometry that better meets your current needs.
But, then you already knew this...
