数据复制已经从我的三个节点中的一个停止。出错的节点上的复制插槽已经消失。有没有人有深入了解发生了什么事或如何解决呢?
联系方式:节点SS1,SS2,SS3和有哪些SSK订阅出版物。从SS2复制但现在失败。使用PostgreSQL 10.1。
SSK PSQL日志:
2019-02-07 10:21:13.953 CST [26274] LOG: logical replication apply worker for subscription "SS2" has started
2019-02-07 10:21:14.309 CST [26274] ERROR: could not start WAL streaming: ERROR: replication slot "SS2" does not exist

SS2复制插槽表:
slot_name | plugin | slot_type | datoid | database | temporary | active | active_pid | xmin | catalog_xmin | restart_lsn | confirmed_flush_lsn
-----------+--------+-----------+--------+----------+-----------+--------+------------+------+--------------+-------------+---------------------
(0 rows)
为了进行比较,SS1复制时隙表中:
slot_name | plugin | slot_type | datoid | database | temporary | active | active_pid | xmin | catalog_xmin | restart_lsn | confirmed_flush_lsn
-----------+----------+-----------+--------+----------+-----------+--------+------------+------+--------------+-------------+---------------------
SS1 | pgoutput | logical | 33280 | DBAdd | f | t | 2113 | | 56655301 | 3/114FB460 | 3/114FB498
(1 row)
复制插槽不只是消失。
某人或某事必须将其删除。
也许主服务器的PostgreSQL数据库日志有有价值的信息。
你最近推动备用?由于复制插槽不可复制的,这将让他们消失。
