We have groupwise server NW6.0 SP3 using NSS

When you map a drive to the MAIL volume, it shows it only has 8GB free (28 used). I know this volume has 340GB capacity.

NSSMU shows the MAIL pool 340GB capacity with 335GB used (only 28GB's worth of data sits on this volume)

When I goto volumes under NSSMU, and goto MAIL, it doesn't show the 340GB but the 8GB free..

what gives?

I received an error saying MAIL is running out of space.
