Dear DRBD community, We are setting up a 2+1 node cluster : - A is master - B is slave - S is an additional spare/backup machine, disconnected most of the time The use cases are : - Normally we sync S once a week then unplug it and keep it safe. The dataset is big (26To) so it has to catch up fast. - Of course when A fails we promote B - But when either A or B fails, we still want HA: so we plug S in and keep it synced until the failed machine is repaired So we intend to set up DRBD between A and B, and use a stacked DRBD resource to replicate (A+B) to S. My question is: if A or B dies and can't be fixed, can S be reconfigured to replace it without a full sync? In other words: can a setup like (A->B)->S be changed to (A->S) with a quick sync? Thanks in advance if you can share your knowledge. Lionel Sausin
