Hi everybody,
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 : failure in starting postgresql

Any ideas ?
Find where file system mounting is completed and start Postgres after
that. I am still figuring out systemd, so I can not offer anything more
concrete.

Magique
