how to convert a vg version in online from 1.0 to 2.0?

Shalom,

You are talking about the file system or the volume group?

What is the OS and version and year and date of the release.

Hello Rajesh,

From the HP Document:
The 2.0 volume groups became available with the March 2008 release of HP-UX 11i v3 (11.31) and the 2.1 volume groups with the 11i v3 2008 September release. Prior to the March 2008 release, only version 1.0 volume groups were available.

You must have 11.31 to see LVM2.x features.

Check with lvmadm command the VG version.(if available)

Also root vg can't have LVM2.x functionality.


Cheers!!

Hi Rajesh,

The vgversion is the command to convert the vg from 1.0 to 2.0, 2.0 to 2.1.

This is a new technical documentation and it will be a great help for you.

The following text is from the LVMv2 on 11.31 white paper

How to migrate?
At this time, there is no in-place migration available. You must migrate by copying data to another volume group created with the desired version.

You face the same situation when you cannot increase the size of a 1.0 volume group and vgmodify cannot do it either. You must copy over the data to a new volume group.

When to migrate?
Because the migration is done by copy, a good time to migrate is when you replace your storage.
