Closed bbqccx closed 10 months ago

bbqccx commented 10 months ago

in my case, i have two computer, one computer have 8 kvrocks node, cluster have 16 nodes。 when one computer carsh or broken ， then failover will in safe mode， "msg":"safe mode, loop ratio 0.40, allnodes: 16, failnodes: 7" beause MinAliveSize is 10，MaxFailureRatio is 0.4，failove will check "nodesCount > MinAliveSize && float64(len(c.tasks))/float64(nodesCount) > MaxFailureRatio"

We would like to be able to configure MinAliveSize and MaxFailureRatio through conf file
