[ https://issues.apache.org/jira/browse/COUCHDB-3271?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel=15832003#comment-15832003 ] ASF subversion and git services commented on COUCHDB-3271: -- Commit ec2235196d7195afab59cedc2d61a02b11596ab4 in couchdb-fabric's branch refs/heads/master from [~vatamane] [ https://git-wip-us.apache.org/repos/asf?p=couchdb-fabric.git;h=ec22351 ] In open_revs, do not count errors in quorum threshold calculation Previously quorum check looked just at the number of replies and decided quorum was met even if it only received errors. For example, if 2 nodes are in maintance mode it might receive this sequence of replies: `rexi_EXIT, rexi_EXIT, ok` In that case after the first two it would decide quorum (r=2) was met, return what it had so far ([]) and kill the remaining worker, who was about to return a valid revision. The fix is to keep track of error replies and subtract them when deciding if quorum was met.
