fstab load order

Mykander · 2013-04-12 23:25:16

Is there any way to force a mount in fstab to be loaded last when starting up a system? Or is there an alternative to rc.local with systemd so I can run "mount -a" during startup before any user has logged in?

I would assume that the entry at the bottom of fstab is the last one to be mounted. If not (due to systemd parallelization), consider writing a systemd .mount unit for the mount, and make use of the dependency resolution logic.

I looked into that, but unless I missed something in the process it won't work for me. As far as I've been able to dig up there is no way to set an explicit dependency, it's simply a case of /a will be mounted before /a/b since /a/b is dependent upon /a being mounted. I need folders in /media mounted before I mount /storage, and they're listed that way in /etc/fstab, but /storage is always loaded before all /media or just after the first /media entry.

As you have observed, the only ordering systemd imposes on mounts is that parents are mounted before their children (and mounts are possibly also ordered after their source, but haven't checked how that works in detail).

Could you explain why you need /storage to be mounted after your folders in /media?

By the way, all the ordering information for .mount units can be seen by doing e.g. "systemctl show storage.mount". If there are no "Before=" or "After=" entries it will be mounted as early as possible.

I'm using aufs to mount /media/disk1 /media/disk2 and /media/disk3 as a pool mounted as /storage.

you could try writing your own servicefile to run mount -a .
