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

[Skylar Thompson]

Like Tina, we're doing bind mounts in autofs. I forgot that there might be
a race condition if you're doing it in fstab. If you're on system with systemd,
another option might be to do this directly with systemd.mount rather than
let the fstab generator make the systemd.mount units:

https://www.freedesktop.org/software/systemd/man/systemd.mount.html

You could then set RequiresMountFor=gpfs1.mount in the bind mount unit.
