Split-brain: cancelled ST results in missing data ------------------------------------------------- Key: ISPN-4900 URL: https://issues.jboss.org/browse/ISPN-4900 Project: Infinispan Issue Type: Bug Components: State Transfer Reporter: Radim Vansa Priority: Critical Attachments: log.txt 1. Cluster [A, B, C, D], in CH 1 segment X owned by [D, C] 2. Split brain [A, B], [C, D]: A and B detects that D is missing, therefore they get view [A, B, C] and start rebalancing, in CH 2 segment X is owned by [C, B] 3. A and B get new view [A, B] (C is missing) and state transfer of X is cancelled, nodes enter degraded mode. 4. Split brain is fixed, all nodes find each other and merge - B starts to be AVAILABLE, but still does not have data for X 5. Subsequent requests on B return null upon cache.get()
