Dear Colleagues, Do you perchance know what is the correct procedure of temporarily taking down a replica in a Patroni cluster, e.g. for 5-10 minutes of hardware maintenance? The problem is that after stopping the patroni process (service) on a replica, patroni removes the corresponding physical replication slot from the leader, and unless the wal_keep_size value is unsanely high, the replica, when up again, cannot restart streaming because the WAL segments are already gone from the leader. Well, you all know: <%%%>LOG: started streaming WAL from primary at B4A0/E2000000 on timeline 8 <%%%>FATAL: could not receive data from WAL stream: ERROR: requested WAL segment 000000080000B4A0000000E2 has already been removed <%%%>LOG: waiting for WAL to become available at B4A0/E2002000 Do you think there is a way to tell Patroni that a replica is down temporarily and its replication slot should not be removed? Or, what am I missing? -- Victor Sudakov VAS4-RIPE http://vas.tomsk.ru/ 2:5005/49@fidonet
