There may occur the following error while performing operations like renaming of files or folders on a Cluster Shared Volume (CSV).




This bug arises primarily when you are not using an administrative account to perform the above operations.

Try any of the following solutions-

  • Execute the function using a process that has administrator privilege.
  • Carry out the operation from a node that doesn’t need CSV ownership.

The Company is working on a permanent solution and may release the same, once found working.
