[英]why rsync command to postgres upgrade replica are duplicating data folder size increasing disc space
I'm following this doc https://www.postgresql.org/docs/current/pgupgrade.html to upgrade my cluster postgres an its replica, but when I run the rsync command, it duplicate the data folder, consuming all the disk space crashing the rsync.我正在关注此文档https://www.postgresql.org/docs/current/pgupgrade.html以升级我的集群 postgres 命令,它复制了它的数据文件夹,当我运行我的集群 postgres 命令时,它复制了它的副本,但数据文件夹空间使 rsync 崩溃。 Here is the rsync command "rsync --archive --delete --hard-links --size-only --no-inc-recursive old_cluster new_cluster remote_dir".
这是 rsync 命令“rsync --archive --delete --hard-links --size-only --no-inc-recursive old_cluster new_cluster remote_dir”。 Any thoughts?
有什么想法吗?
The problem was the alignment of directories, due to the difference between origin and destination it ended up getting lost and copying everything.问题是目录的 alignment,由于起点和终点之间的差异,它最终会丢失并复制所有内容。 well succeeded command: "rsync --exclude pg_wal --archive --delete --hard-links --size-only --no-inc-recursive /pgdata/homologacao/11 /pgdata/homologacao/14 hom-replica:/pgdata/homologacao"
成功的命令: “rsync --exclude pg_wal --archive --delete --hard-links --size-only --no-inc-recursive /pgdata/homologacao/11 /pgdata/homologacao/14 hom-replica:/ pgdata/homologacao"
