From 8a45a0e480f7e8c6ea1195f77ce3810d4817dc37 Mon Sep 17 00:00:00 2001 From: Krishnan Parthasarathi Date: Tue, 3 Apr 2012 15:37:25 +0530 Subject: glusterd: Added volume-id to 'op' dictionary Volume-id passed in op dictionary would help detect possible split brains among peers in a cluster. The idea is to check if the volume's id and the vol-id that was passed are equal. ie, same volume name, but different volume id indicate that glusterd 'metadata' of one of the participating peers is stale or there is a split brain. This is over and above the existing checksum based validation of peer supplied cluster 'metadata' (ie, volume info file).
