Hi, Thank's for the clarificaiton! That's what I expected. I looked into https://github.com/luqmanahmad/ignite-plugins and decided to implement my own SegmentationResolver to deal with these cases. Cheers Sam -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/

Hello! After all, it is only you who can decide whether your cluster has segmented or not. The traditional solution is "the largest one wins", but if the parts of cluster can't communicate, it becomes undecidable. Regards, -- Ilya Kasnacheev пн, 14 сент. 2020 г. в 12:01, sue : > Hi Denis, > >

Hi Denis, Thank you for your reply. Restarting all the nodes in the partitioned segment would work for my usecase. Is there a way to detect such a scenario with TCP/IP Discovery mode in Ignite? In my test I didn't get any EVT_NODE_SEGMENTED events, only EVT_NODE_FAILED. So the individual cluste

BTW, you can try zookeeper discovery, I think it's the easier way to resolve split-brain problem: https://www.gridgain.com/docs/latest/developers-guide/clustering/zookeeper-discovery пт, 11 сент. 2020 г. в 14:13, Michael Cherkasov : > Make sure first you stop all nodes in one segment and only th

Make sure first you stop all nodes in one segment and only then start them, rolling restart might not fix cluster segmentation. пт, 11 сент. 2020 г. в 09:08, Denis Magda : > Hi Samuel, > > With the current behavior, the segments will not rejoin automatically. > Once the network is recovered from

Hi Samuel, With the current behavior, the segments will not rejoin automatically. Once the network is recovered from a network partitioning event, you need to restart all the nodes of one of the segments. Those nodes will join the other nodes and the cluster will become fully operational. Let me

Ignite Segmentation Behaviour

2020-09-11 Thread Samuel Ueltschi
Hi I've been testing Ignite (2.8.1) and it's behaviour under network segmentation. According to the docs, Ignite nodes should be able to detect network segmentation and apply the configured SegmentationPolicy. However the segmentation handling didn't trigger as I would have expected it to do. F
