Hi,

why would you even possibly want a non-relocatable VG ? I don't think you can change it ...

Code:

mklv -y'<name_of_lv>' -t'jfs2' -x'<max_pp_in_lv>' rootvg <size_of_lv_in_pp>

where <max_pp_in_lv> is the size you want the lv to maximum grow to and <size_of_lv_in_pp> is the size you want it to be now. You can later extend a filesystem residing in this lv just with chfs up to the size of max without first growing the lv. It would be automatically spread (poor man striped) across all disks CURRENTLY in your volumegroup. If you later add more disks to your vg, than this lv would remain spread across the disks you have now as long as you don't run a reorg command - any newly created lv's would be spread across the new amount of disks.

If you want afterwards to create a filesystem within this created lv than you would do it i.e. like this (I assume an inline log, that you want it auto mounted after a system boot and rbrw mounted in my sample):

Code:

crfs -v jfs2 -d'<name_of_lv>' -m'<mountpoint>' -p'rw' -A yes -a options='rbrw' -a logname='INLINE'

This filesystem would have the size <size_of_lv_in_pp> from the mklv command.

Hope this helps
kind regards

GNOME-DISKS(1)							gnome-disk-utility						    GNOME-DISKS(1)

NAME

       gnome-disks - the GNOME Disks application

SYNOPSIS

       gnome-disks [OPTIONS]

DESCRIPTION

       gnome-disks is the command to launch the GNOME Disks application. Disks provides a way to inspect, format, partition and configure disks
       and block devices.

       The Disks application is single-instance. What this means is that if the application is not already running when the gnome-disks command is
       invoked, it will get launched and the command invocation will block until the application exits. Otherwise the existing application
       instance will be used and the gnome-disks command will exit immediately.

OPTIONS

       The following options are understood:

       --block-device DEVICE
	   Switches to the Disks application and selects the block device given by DEVICE (for example, /dev/sda).

       --block-device DEVICE --format-device [--xid WINDOW-ID]
	   Shows the "Format Volume" dialog for the block device given by DEVICE (for example, /dev/sdb1). If WINDOW-ID is given, makes the dialog
	   transient to the given XID.

       --help
	   Prints a short help text and exits.
