我在CentOS上有Postgresql-9.2.10。
我遇到以下错误:
DETAIL: Multiple failures --- write error might be permanent.
ERROR: could not open file "pg_tblspc / 143862353 / PG_9.2_201204301 / 16439 / 199534370_fsm": No such file or directory
这是因为我停止了PostgreSQL服务,运行pg_resetxlog
并启动了服务。 pg_log
中的日志看起来不错,列出的服务没有任何问题。
DML运行良好,但不是CREATE TABLE
之类的DDL语句,否则会抛出错误消息,或pg_log
中的日志中看不到任何内容。
如果我尝试创建一个表,则没有任何反应,看起来该语句被锁阻止。
所以我尝试了以下查询来查找锁:
SELECT blocked_locks.pid AS blocked_pid,
blocked_activity.usename AS blocked_user,
blocking_locks.pid AS blocking_pid,
blocking_activity.usename AS blocking_user,
blocked_activity.query AS blocked_statement,
blocking_activity.query AS blocking_statement
FROM pg_catalog.pg_locks blocked_locks
JOIN pg_catalog.pg_stat_activity blocked_activity ON blocked_activity.pid = blocked_locks.pid
JOIN pg_catalog.pg_locks blocking_locks
ON blocking_locks.locktype = blocked_locks.locktype
AND blocking_locks.DATABASE IS NOT DISTINCT FROM blocked_locks.DATABASE
AND blocking_locks.relation IS NOT DISTINCT FROM blocked_locks.relation
AND blocking_locks.page IS NOT DISTINCT FROM blocked_locks.page
AND blocking_locks.tuple IS NOT DISTINCT FROM blocked_locks.tuple
AND blocking_locks.virtualxid IS NOT DISTINCT FROM blocked_locks.virtualxid
AND blocking_locks.transactionid IS NOT DISTINCT FROM blocked_locks.transactionid
AND blocking_locks.classid IS NOT DISTINCT FROM blocked_locks.classid
AND blocking_locks.objid IS NOT DISTINCT FROM blocked_locks.objid
AND blocking_locks.objsubid IS NOT DISTINCT FROM blocked_locks.objsubid
AND blocking_locks.pid != blocked_locks.pid
JOIN pg_catalog.pg_stat_activity blocking_activity ON blocking_activity.pid = blocking_locks.pid
WHERE NOT blocked_locks.granted;
答案 0 :(得分:0)
您可能使用pg_resetxlog
损坏了PostgreSQL群集。你究竟是怎么运行这个命令的?
我会从最后一次良好的备份恢复。
