Hi 备机同步失败，尝试用gs_ctl build修复时，报下面错误：我一直用的是初始化数据库的超级用户postgres，配主备没问题，这里 " 不能用 initial user " 但是在哪里指定用什么user？能用啥user呢？文档里找不到详细的说明。 [postgres@pg_155 hadb-opengauss]$ gs_ctl build -D _pg_root -b incremental [2022-04-02 16:19:26.630][9988][][gs_ctl]: gs_ctl incremental build ,datadir is /mnt/disk01/hadb-opengauss/_pg_root waiting for server to shut down......... done server stopped [2022-04-02 16:19:32.677][9988][][gs_ctl]: fopen build pid file "/mnt/disk01/hadb-opengauss/_pg_root/gs_build.pid" success [2022-04-02 16:19:32.677][9988][][gs_ctl]: fprintf build pid file "/mnt/disk01/hadb-opengauss/_pg_root/gs_build.pid" success [2022-04-02 16:19:32.678][9988][][gs_ctl]: fsync build pid file "/mnt/disk01/hadb-opengauss/_pg_root/gs_build.pid" success [2022-04-02 16:19:32.689][9988][][gs_rewind]: set gaussdb state file when rewind:db state(BUILDING_STATE), server mode(STANDBY_MODE), build mode(INC_BUILD).

关于PTRACK临时文件位置
by Don't mind☭ 02 Apr '22

02 Apr '22

HI      关于ptrack增量备份块功能的说明实在稀少。现在我已经知道pg_cbm_get_changed_block这个函数可以获取数据文件变化块，然后我有几个问题。    1.ptrack会使用位图来记录变化块。根据postgres pro提供的文档，ptrack会产生两个临时文件并且在临时文件中也会记录lsn位置。请问opengauss也会产生这两个临时文件么？这个临时文件的位置在哪，lsn号是否也记录在其中。    2.lsn号是永远有效还是多久会失效。我们需要根据lsn的特性确认我们的备份策略。lsn是存储在库中，wal日志中还是哪里，多久之前的lsn号将无法查询？这将影响到我们的增量备份间隔多久需要重新进行全量备份周玥铖电话：18115127620 e-mail:1224077693@qq.com
