在pgxc_ctl工具中从GTM主机运行几乎任何命令(例如createdb test)后,我收到以下错误:
FATAL: GTM error, could not obtain snapshot. Current XID = 0, Autovac = 0
PostgresXL是configured并安装在4个节点(/ etc / hosts)上:
172.23.102.115 coordinator001
172.23.102.116 datanode001
172.23.103.0 datanode002
172.23.102.114 gtm001
这样每个人都可以 ssh 进入另一个,而pg_hba.conf包含:
host all all 0.0.0.0/0 trust
GTM节点有configuration
感谢任何有关下一步挖掘的提示或想法。

在直接连接期间出现此错误:
psql -h coordinator001 -p 6668 -U postgres testdb
psql: FATAL: GTM error, could not obtain snapshot. Current XID = 0, Autovac = 0
