Extending a CSV by using Diskpart or PowerShell is not blocked from a non-coordinator node
Consider the following scenario:
- You have a failover cluster that has a Cluster Shared Volume (CSV) configured.
- You have to extend the CSV volume.
- From a non-coordinator node, you use the Diskpart command or a Windows PowerShell cmdlet to extend the volume.
Additionally, you cannot reduce the extended volume. If you try to do this, the process fails and you may receive the following error message:
This problem occurs because an extend write operation causes the Cluster Shared Volumes File System (CSVFS) to extend all or some of the following values:
- File allocation size
- File size
- Valid data length
In the Cluster GUI, you may notice that the Extend Volume option is greyed out on a non-coordinator node.
To resolve this problem, do not run any metadata operation from a non-coordinator node.
For more information about clustering and high-availability, see the following Failover Clustering and Network Load Balancing Team Blog article:
To work around this problem, increase the disk space that’s allocated to the CSV. To do this, extend the disk on the CSV owner node (coordinator node) by using the Cluster GUI, the Diskpart tool, or Windows PowerShell.
Note After you extend the disk, all displayed disk sizes and capacity values are updated to the correct size.
