PostgreSQL Cascade streaming replication problem
Hi everyone, i have one master and two slaves - cascading replication. Master -> Slave1 -> Slave2 Slave2 crashed two days ago. Problem is on Slave1, where are comulating WAL files. Archive mode is turn off. There is about 6.000 WAL Files, but in folder archive_status are files with .done name. How can I remove WAL files, which are "waiting" for Slave2? I changed configration on Slave1 (i commented this options "wal level = hot_standby" and "max_wal_senders = 1"). But without effect. What did i do wrong? I need stop comulating WAL files and remove old WAL files, which are processed and are only "waiting".. Thank you for your tips. Regards, Jakub
Re: PostgreSQL Cascade streaming replication problem
I have set up wal_keep_segments = 100 on Slave1, but no effect. I tried comment wal_keep_segments, no effect too... Actually i have 8.500 WAL Files, disk space is low. I tried drop replication slot on Slave1, no effect. Is possible to manually remove WAL files?

Hi everyone, problem is solved. There was a delay between setup (drop replication slot) and execution.
