[DUPLICATE] The possibility of another qdisk being able to take the place of a failed one would address the problem of losing the storage array hosting the qdisk.

Issue

There was a question about whether it's possible to mirror a qdisk across storage arrays or whether multiple qdisks could be used. From the research I had done, it appears that neither of those would be a possibility, and told that to the team. The consensus was to keep the quorum disk requirement if losing one storage array meant losing quorum. Of course, if you know of any method of doing this without losing quorum, that would be welcome knowledge.

To be clear, with your current configuration, you want the cluster to not be quorate if the qdisk is lost. What you are essentially asking is whether there is a way to ensure when one "qdisk" is lost, "another one" would be available to take its place.

As an example of something that works this way already - with clvm mirroring we are using the failure policy of 'allocate' for our mirror log. There is a small extra PV that we set aside to be a spare device for the mirror log. During testing, when the active mirror log device was brought offline, the extra PV was automatically used for the mirror log.
