How to change the Max PE value in online(used) volume group.

[Steven E. Protter]

Shalom,

In hp-ux 11.31 you can use vgchange.

Other versions of hp-ux you must vgexport, and vgcreate and vgimport the volume group. Have to start over. -s parameter of vgcreate.

Sorry, but vgimporting is just going to put it back like it was. You'll need to recreate it using vgcreate, then restore your data.

-s option is Per PE size.
-e option is Max PE size.

For LVM version 2.x see

â e max_pe is not needed for 2.x volume groups because the 2.x metadata format is provisioned so that the
number of physical extents can always grow to the maximum size specified with â S.
