I already try to change the dependencies with postgresql.service (adding as a prerequesite lvm scan, iscsi) . The mounting began before postgresql but the mount was successfull after the failure. ----- Mail d'origine ----- De: Adrian Klaver <adrian.klaver@xxxxxxxxxxx> À: proj@xxxxxxx, pgsql-general@xxxxxxxxxxxxxx Envoyé: Wed, 17 Feb 2016 18:35:15 +0100 (CET) Objet: Re: Pgsql troubleshooting & Iscsi On 02/17/2016 09:07 AM, proj@xxxxxxx wrote: > 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).

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 > > > > systemd: Starting Remote File Systems (Pre) > systemd: Reached Remote File Systems (Pre) > systemd: mounting /var/lib/pgsql ^ File system not mounted yet. > systemd: starting PostgreSQL database server > kernel sdb: unknown partition table > postgresql-check-db-dir: "/var/lib/pgsql/data" is missing or empty ^ Cannot find mount point > kernel: xfs (dm-4): Mounting V4 Filesystem > postgresql.service: control process exited, code=exited status=1 > Failed to start PostgreSQL database server. > Unit postgresql.service entered failed state > sd 2:0:0:0: [sdb] attached SCSI disk > starting LVM2 PV scan on device 8:16 > kernel: xfs (dm-3): Ending clean mount > systemd: Mounted /var/lib/pgsql ^ Now file system is mounted. > Starting Remote File Systems > Reached target Remote File Systems > > Any ideas ? Find where file system mounting is completed and start Postgres after that.
