可以看到，有2个实例一直处于“ Not In Sync”状态，使用gpstate -e可以看到，需要同步的wal日志还剩600G，还是相当的大。

分析

分析发现，sdw1的6002实例和6001实例的wal日志的确还有600G需要传输：

[gpadmin@sdw1 gpseg2]$ cd /dbaup/opt/greenplum/data/primary/gpseg2/pg_xlog/ [gpadmin@sdw1 pg_xlog]$ du -sh . 610G .

1 2 3

[gpadmin@sdw1 gpseg2]$ cd /dbaup/opt/greenplum/data/primary/gpseg2/pg_xlog/ [gpadmin@sdw1 pg_xlog]$ du -sh . 610G    .
