Hi,
I want to check 2 conditions on redis, where it should be master and on other checks, at least 2 of 3 sentinel nodes should provide this redis-instance being master.
Therefore, number of servers found on another backend check, is reused and if number if found server is at least 2, it should be selected.
However, condition with use-server and nbsrv is totally ignored. ge 2 is not working and lt 1 for example, not, too.
Any ideas?
