After the initial setup it didn’t take long until the assigned volume sizes weren’t sufficient anymore. After looking around it seem that the diskpart tool will extend a Cluster Shared Volume with a few command.
- First, increase the size of the LUN on your storage to the required size
- Open up a command prompt on the current owner node
- Run diskpart
- >> rescan
- >> list volume
- >> select volume x
- >> extend volume
- >> list volume
That’s it. The volume will be extended to the maximum size as the LUN has been increased to.
