Allocating free PE

[Donald Lalonde]

Hi,

I see that I have a lot of free PE on vg00.
But, I reached the Max PE per PV.
How can I access the free space?

Thanks
Don

You only have one disk in vg00, and it is smaller than MaxPEperPV, so You can use the free space without problems. :)

MaxPEperPV will impose a problem only if You want to add a disk that is larger than 8*4340 MB in size, which is everything greater than 36GB.

I'll assume You know how to add a LV if needed, otherwise please ask.

I was looking at the Total PE as the allocated PE.

Yep, I know how to allocate the space now.

Thanks

My mistake...

Donald,

from the output you provided, you do not seem to be in trouble at all. You are able to use all your free PEs without any problems. I think you have a confusion about some LVM concepts. Max PE per PV indicates the number of physical extents that you can have per physical disk device and has nothing to do with using those extents. If confusion is somewhere else, please provide detailed information and more help will follow.
