I installed a postgresql database on Redhat 7.1 and I decided to move the database on an ISCSI device (LUN) inside a logical volume, mounted at starting of the machine (xfs formatted). The mounting point is /var/lib/pgsql
At the boot of the server, postgresql.service is in failed status.
In messages.log:
systemd: mounting /var/lib/pgsql starting PostgreSQL database server kernel sdv: unknown partition table sd 2:0:0:0: [sdb] attached SCSI disk xfs (dm-4): Mounting V4 Filesystem postgresql-check-db-dir: "/var/lib/pgsql/data" is missing or empty postgresql.service: control process exited, code=exited status=1 Failed to start PostgreSQL database server. When I'm logged on the server, if it try to start manually the database : systemctl start postgresql --> OK (and I don't lose any data, database is available)
I think it's a problem of order in the boot process : network service must be started, then iscsi, then lvm etc... So I tried to force dependencies on the /usr/lib/systemd/system/postgresql.service adding "After=lvm-pgscan.service iscsi.service" etc... but the result is the same :
