What must be identical for the Quorum and Storage disks?

For Quorum and Storage disks in a system that needs to maintain consistent and reliable access to data, the drive letters must be identical. This is crucial because the operating system and applications reference these drives using their designated letters. If the drive letters differ between the two disks, it can lead to confusion and errors as the system attempts to access data or perform operations across the disks, causing potential issues with data consistency and availability.

Maintaining the same drive letters ensures that the paths to the data remain consistent, allowing for seamless operation in failover situations or when accessing shared resources. This standardization helps prevent misconfiguration, ensuring that the system recognizes and accesses the appropriate resources without interruption.

In contrast, while file system type, disk size, and encryption type are important configurations in their own right, they do not need to be identical for Quorum and Storage disks. Different file systems can coexist, and drives can vary in size while still functioning correctly, as long as the system is configured to account for those differences. Similarly, the types of encryption used can be different without impacting the ability of the quorum or storage functionalities to operate effectively.
