Starting at 7am on Wednesday, Oct. 7th, we will be performing rolling upgrades of the  DMZ GPFS nfs cluster..  Each DMZ GPFS nfs cluster server upgrade may potentially cause a brief 90 second NFS blip for all public services in the DMZ i.e. xen hosts and clients, web service.  This GPFS rolling upgrade does not affect nfs access for the compute grid nodes or dept linux machines.  We expect the maintenance to be completed by 8am at the latest.
