From 95c6bff3561eedaf7c7de287bc4a002720605a8d Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Beno=C3=AEt=20Canet?= Date: Fri, 21 Feb 2014 22:21:15 +0100 Subject: quorum: Add quorum mechanism. This patchset enables the core of the quorum mechanism. The num_children reads are compared to get the majority version and if this version exists more than threshold times the guest won't see the error at all. If a block is corrupted or if an error occurs during an IO or if the quorum cannot be established QMP events are used to report to the management. Use gnutls's SHA-256 to compare versions. --enable-quorum must be used to enable the feature.
