[gpfsug-discuss] How to do multiple mounts via GPFS

[Jakobs, Julian]

I've ran into the same problem some time ago.
What worked for me was this shell script I run as a @reboot cronjob:

#!/bin/bash
while [ ! -d /gpfs1/home ]
do
  sleep 5
done
mount --bind /gpfs1/home /home

I tried a bind mount, but perhaps I'm doing it wrong. The system fails to boot because gpfs doesn't start until too late in the boot process.
In fact, the system boots and the gpfs1 partition isn't available for a good 20-30 seconds.

/gfs1/home    /home    none     bind
I've tried adding mount options of x-systemd-requires=gpfs1, noauto.
The noauto lets it boot, but the mount is never mounted properly. Doing a manual mount -a mounts it.
