QUORUM DISK

Answers

  • Hi,

    The definition of quorum is that a quorum is the minimum number of members that must be present to make the proceedings of a meeting valid. When it relates to Windows clusters, when we're talking about quorum we're effectively trying to determine whether or not there are enough votes there for the cluster to continue to be a cluster. If you think about cluster configurations across multiple different nodes, there are different failure states that can create a situation where you might not necessarily even know if the cluster continues to exist or not, and so it's this configuration of quorum that helps you validate where the cluster actually is across the range of failures that can possibly occur.

  • 1 GB is more than you realy need. It's only there to store the cluster database. The reason is not for capacity reasons, but the "optimum minimum" for the NTFS filesystem itself.

  • Thanks Nedim for detailed explanation. Why is it recommended to create up to 500 MB- 1 GB in size for quorum disk? How to determine what size I need for cluster or before I create one?
