Increase Physical Extent size for Volume Group

[Nabil_11]

Hi,
I configured MC/ServiceGaurd and its work prefect,
I need to increase vg04 it was ( 50 GB )
I define new disk 100 GB
I execute vgextend /dev/vg04 /dev/dsk/cxtxdx
and I export it to the second member
it works properly
BUT I found that the whole space is 100 GB rather that 150 GB
I know its vgcreate limitation I should modify the PE number per PV
or the PE size (its 4 MB)
but how to do that without backup and restore the data and not create the vg from scratch
I dont have online JFS
Regards

You will have to re-create the VG.
1. Increase PE size
2. OR increase no. of extents.

man vgcreate for details.

The only time you can define pe-size or max-pe is at vgcreate time so the only way you're going to be able to do this is to backup, re-create and restore. Sorry.

The max PE's value is set when the VG is created; unless you plan ahead and override the defaults, you are limited to the largest physical volume size found when the vgcreate was done. You have to backup and recreate the VG and restore OR vgreduce your 100GB disk and recreate it as 2 50GB LUN's.
