VG Problems

[Rafael Mendonça Braga]

Hello there...
Trying to extend a VG, I'm receiving this message:

"At least one of the disks you have chosen is larger than the maximum disk size allowed by volume grop vg01 (51792 Mbytes). These Disks can still be used, but any capacity beyond the volume group limit will be wasted."

How can I do to solve it?!

Thanks,

Hi Rafael,

If you do a vgdisplay on the vg in question you should see a value for "Max PE per PV". if you multiply this value by the PE size you will get the maximum size disk that you're allowed to add to the volume group.

This value is set when you create a volume group and unfortunately once it is setup it cannot be changed.

To rectify the problem you will need to recreate the volume group using vgcreate and specify the max pe size allowed using the -e flag.

You are hitting the problem of max pes in a VG. man vgcreate, check -e option. you can still add PV to vg, but can not user all of it's space. The max pe that will be used will same as that the first pv added to VG.
