Hello, I would like to create a three nodes cluster with multi-master
system, but when I go to define the
agreements between nodes I get different results depending on the order
in which I create the agreements.
The nodes hostname are test-389-ds-1, test-389-ds-2 and test-389-ds-3.
If I define the agreements in the following order, some replications
fail after the last agreement creation:
test-389-ds-1 -> test-389-ds-2
test-389-ds-2 -> test-389-ds-1
test-389-ds-1 -> test-389-ds-3
test-389-ds-3 -> test-389-ds-1
test-389-ds-2 -> test-389-ds-3
If I define the agreements in the following order, all is ok:
test-389-ds-1 -> test-389-ds-2
test-389-ds-2 -> test-389-ds-1
test-389-ds-1 -> test-389-ds-3
test-389-ds-2 -> test-389-ds-3
test-389-ds-3 -> test-389-ds-1
test-389-ds-3 -> test-389-ds-2

Is there a method to know the correct sequence of definition of the
agreements?

Alberto.
