Re: Increasing Max PE per PV
You can not increase the Max PE per PV number!
The maximum PV you can create in a VG depend on the Max PE per PV and PE size(Mbytes).
This number was definded when you create new VG.
Hope this helps

Re: Increasing Max PE per PV
It is not possible to increase max PE/ PV Parameter after the vg creation. You have to set this parameter when you create a vg manually ( vgcreate -e
You can create a new vg with maximum PE/PV for the new LUN & create lvols, transfer all the data from the current vg lvols to new vg lvols. Later you can do a vgexport of both the vgs & import the new vg with the old vg name.

Shameer

I have used it multiple times to do exactly what you want to do. There are some situaitons where it does not work.
Please make sure you get it from a good source for your Operating system. Please also make sure you have good LVM patches.

Re: Increasing Max PE per PV
The max PE value is set when the VG is created. You will need to recreate the VG, manually
# vgcreate -e
You can calculate this based on the BIGGEST - LUN that you may want to add to LVM.
The totale LUN size is no.of PE*PEsize.
The maximum value for the MAX PE per PV is 65535, so you can adjust the PE size upto 256MB wheras the default value is 4 MB.
With Regards,
Siva.
otherwise system take the optimal value according to the size of current disk/ LUN.
