migrate filesystem

kholikt — Thu, 05 Dec 2002 03:44:46 GMT

I have a va7400. I understand LUN cannot be resize. I have a VG named vgora that I seldom use and I am thinking of removing vgora volume group. Can I do a vgextend so that this free LUN unit can be used for another VG that is running out of Free PE.

If you want to use disks of vgora onto another volume-group, then first get the disk details of vgora (vgdisplay -v vgora will give you the disks' path). Then vgexport vgora and (optionally) run pvcreate on disks that are freed up. Now run vgextend on desired VG and include these disks.

If that's what you want, the short answer is - yes!

Hi kholikt,

You certainly can.
I'd do a fbackup (2's better) of the filesystems now in vgora....just in case. And while you're at it, including the VG you wish to extend would be wise.
Keep in mind, you can't go below the LUN value - you'd have to add the entire LUN to the VG you're extending.

Rgds,
Jeff

What you can do is take a backup of the volumes of vgora.
THen you can vgreduce the physical volumes from the vgora volume group.

#vgreduce
Then do a vgremove to remove the volume group

Then you can do a vgextend to add those physical volumes into the existing group

Thanks
