Okay, I'm no systemd expert, though I play one at work. :) You might try adding this to your mysql unit file:
[Unit] Description=MySQL Server -After=nss-lookup.target network.target remote-fs.target time-sync.target -Wants=nss-lookup.target network.target remote-fs.target time-sync.target +After=nss-lookup.target network.target remote-fs.target time-sync.target iscsi-disk.mount +Wants=nss-lookup.target network.target remote-fs.target time-sync.target iscsi-disk.mount And, of course, run "systemctl daemon-reload" after the change. This is probably an issue for the mysql package maintainers, but this might get you working.
