The Microsoft cluster server could not write file (filename ). The disk may be low on diskpace, or some other serious condition exists.
The cluster service attempted to create a temporary file in the \Mscs directory on the quorum disk. Lack of disk space or other factors prevented successful completion of the operation.
Check the quorum drive for available disk space. The file system might be corrupted, or the device might be failing. Check file-system permissions to ensure the cluster service account has full access to the drive and directory.
