Description of problem: ----------------------- 'virt' group file which contains the volume options for optimizing volume for virt-store usecase, includes server side quorum. Server-side quorum is not fool-proof for preventing split-brain in the volume Version-Release number of selected component (if applicable): ------------------------------------------------------------- RHGS 3.1 How reproducible: ----------------- NA Steps to Reproduce: ------------------- 1. cat /var/lib/glusterd/groups/virt Actual results: --------------- server-side quorum is enabled in virt group file Expected results: ----------------- server-side quorum should be disabled Additional info: ---------------- By default, server-side quorum is turned off, and so its simple to remove the entry "server-quorum-type=server" from virt group file
Apparently GSS are finding that for replica 2 set-up, adding a dummy node and enabling server quorum is reducing the probability of files ending up in split-brain. So it might be better to retain this option for now. Once arbiter volumes are made available for downstream, it might make sense to remove this option.
Closing this bug since there is no consensus on the future of server-quorum as of today. If a firm decision can be arrived at for disabling it or even removing it altogether, the bug can be reconsidered.
