a) Some config changes still require a server restart.
b) It sounds like it has no updateRef line configured? If this server
is
no longer a write node, why are you sending writes to it?
I was trying to remove the slave, make it standalone and remove some records for testing.
Was it a slave, or was it an MMR node?
I was using olcSyncrepl
it wasn't an MMR node, I don't know why you would be messing with olcMirrorMode, since that's only for MMR configurations.
Because at some point I was trying anything I could find on the internet.
