断电后gitlab报500错误启动出错

异常断电后，gitlab报500错误，重启无效

通过sudo gitlab-ctl reconfigure启动时, 提示 [execute] pgsql:could not connect to server:

通过sudo gitlab-ctl start启动时, 提示 timeout:down:postgresql:ls, normally up, want up

查看/var/log/gitlab/postgres/current日志发现,

--05_07::01.37753 FATAL:  pre-existing shared memory block (key , ID ) is still in use
--05_07::01.37754 HINT:  If you're sure there are no old server processes still running, remove the shared memory block or just delete the file "postmaster.pid".

按照提示，删除"postmaster.pid"

root@ubuntu-:/var/opt/gitlab/postgresql/data#  rm postmaster.pid

重新执行sudo gitlab-ctl reconfigure gitlab可以正常启动了
