Hi guys.
I have a peculiar case - to me at least - here.
Unless I tell cluster to move resource to a node (two-node
cluster) with '--master' cluster keeps both nodes as "slaves"
As soon as I remove such a constraint both nodes start to log:
...
3442363:M 07 Jul 2022 20:05:31.561 # Setting secondary
replication ID to b14b339d4b0162c3bcd73c9591b60fa491f475dd,

qbuf=48 qbuf-free=40906 argv-mem=25 obl=0 oll=0 omem=0
tot-mem=61489 events=r cmd=slaveof user=default redir=-1')
and then infamous:
...
3442363:S 07 Jul 2022 20:11:24.184 # Unable to connect to
MASTER: (null)
3442363:S 07 Jul 2022 20:11:25.187 * Connecting to MASTER
no-such-master:6379
..
What is PCS/agent getting wrong there?
btw. OCF Redis does not need 'redis-sentinel.conf' , right?
many thanks, L.
