What will happened if quorum would not available in case of Disaster Recovery?
It seems I missed something on DR configuration regarding quorum settings which may impact during Disaster Recovery situation. Please review the given below configuration and advice regarding Quorum configuration which should be best fit for DR conditions and also let me know what steps I need to perform quorum side before or after SQL AG force fail-over to DR site. **SQL 2012 AG WSFC with standalone nodes, 2 node on primary site with synchronized auto fail-over and 1 DR node with A-synchronized manual fail-over (Multi-subnet).** Quorum is configured with file server path. Also I didn’t change any vote and anything and all are with default setting so advice if anything needs to change.
3 node cluster with a file share witness can sustain the loss of 1 node. If the 2 nodes in primary site where to go offline due to a site failure so would your DR node. You will need to look at the possibility of a 4 node cluster with fileshare or a 5 node cluster to always ensure you have a majority vote
