Hi
we recently did upgrade from 2.1. to 3.1.1 . We noticed that when we restart
one of the nodes all nodes are starting to report errors and whole cluster
become unusable. To fix the issue we have to restart the rest of the nodes as
well. This does not seems like reliable design of v3, I do not think is normal
restart of one of nodes to bring the whole cluster down. Even if our cluster is
not setup correctly still that behavior seems very odd to me.
`[cluster]
q=5
n=3
placement = z1:2,z2:1`
Errors we get after restart of pbx1-z2:
- on pbx1-z2:
