We have two geographically separate data centers connected by 4 x Gigabit links (in 2 trunks). Our HA clusters are distributed between the data centers, with each node of a 2-node cluster in a separate data center. (In the case of our 3-node clusters, 2 nodes are in one data center and the 3rd node is in the other data center.) Cluster membership information is communicated though both of the Gigabit trunks, where each trunk is a separate Corosync ring. DRBD is replicated through one of the trunks. Question: If the links between the data centers are severed, split brain will occur. What is the best way to provide quorum from a third location out on the Internet? Note: I posted this question to the Linux HA list, too, because I was not sure which was better suited. -- Eric Robinson Disclaimer - March 2, 2012 This email and any files transmitted with it are confidential and intended solely for drbd-user at lists.linbit.com.
