while trying to implement sentinel on redis ( 1 master, 2 slaves), I have been unable to delete keys stored on it.
Sentinel version : 6.2.0
I check for keys with exists() and then trigger delete on the keys.
$redis->exists() on keys does return true.
$redis->del($key) -> returns zero all the time. I have tried passing keys as an array and also as single key one by one. Neither of them worked.
I have been able to perform deletion with exact same code on db Index 0. It doesn't work on any other index.
