My GroupWise Post Office NSS Volume is running low on space. I'm wondering what the recommended method is for increasing the Volume Size.

This is an OES 11 SP2 vmware VM Server running eDirectory 8.8 Sp8

A 75 Gig Lun was carved out for the OS and a separate 500 Gig Lun was carved out for the NSS Post Office Volume.

I can grow the Volume Lun from within vCenter and then expand the NSS Pool and NSS Volume via nssmu, or

I can carve out a second Lun and then add that to the NSS Pool and NSS Volume.

Either way, the OS will see the free space as a second segment to the Volume.

In this scenario is there a preferred method to grow the Pool/Volume and why?

Thanks, Dave.
