According to wikipedia:
Quote:
Cluster Shared Volumes (CSV) is a feature of Failover Clustering first introduced in Windows Server 2008 R2 for use with the Hyper-V role. A Cluster Shared Volume is a shared disk containing an NTFS volume that is made accessible for read and write operations by all nodes within a Windows Server Failover Cluster.
Quote:
Maintenance mode is a mechanism provided through cluster.exe and the Failover Cluster API that places the specified resource in a mode that will disable health checking. After maintenance mode is enabled for a resource, Resource Monitor will ignore health check calls on the resource even though the resource is left in online mode.
Do we "really" need to put them in maintenance mode during an upgrade? What is new in 2008 that requires this where 2003 does not? Why isn't multipathing good enough anymore?
