After rebooting Red Hat Satellite server, PostgreSQL service won't start.
环境
- Red Hat Satellite 6.4
问题
- After rebooting Red Hat Satellite server, PostgreSQL service won't start.
- Having /var/lib/pgsql on a NFS filesystem.
- Executing katello-service restart, the services start correctly
决议
- Append the parameter
remote-fs.target next to existing line After=network.target in the file /usr/lib/systemd/system/postgresql.service as below:
Raw
After=network.target remote-fs.target <<< Append this
根源
- After the machine reboot, postgreSQL services was starting before NFS mounted
/var/lib/pgsql directory. Adding the dependency remote-fs.target to systemd services' files postpones postgres services to wait for NFS mount to be loaded.
诊断步骤
- /var/log/message shows below error:
Raw
Nov 30 10:43:29 satellite systemd: Starting Logout off all iSCSI sessions on shutdown...
Nov 30 10:43:29 satellite postgresql-check-db-dir: "/var/lib/pgsql/data" is missing or empty.
