Bullet proof mount strategy for mounts in a vbox [SOLVED]

graysky · 2013-12-23 11:31:15

Virtualbox shares require modules in [community]/virtualbox-guest-modules-lts which are not always built against the most recent kernel in the repos.[1,2] Systemd treats the error of the mount's inaccessibility as critical and stops the normal boot up entering emergency mode. Is there a more intelligent way I can define a share-mount in my vbox such that it will fail silently or at least boot the system for ssh access?

I have tried both of these /etc/fstab configurations, but each ends in the emergency mode drop if the modules are bad:

Config 1:

data-vbox /mnt/data vboxsf uid=1000,gid=100 0 0

Config 2:
data-vbox /mnt/data vboxsf,noauto,x-systemd.automount uid=1000,gid=100 0 0

1. https://bugs.archlinux.org/task/38097
2. https://bugs.archlinux.org/task/38247

EDIT: A typo in config 2 kept me from finding my own answer. The line works when composed correctly:

data-vbox    /mnt/data     vboxsf   noauto,x-systemd.automount,uid=1000,gid=100 0 0

Have you tried it with this :

data-vbox /mnt/data vboxsf noauto uid=1000,gid=100 0 0

@Lone - Yes, but that drops to an emergency shell at boot as well (added a comma between vboxsf and noauto).

I'm assuming these are fstab entries (Edit: I should've looked harder, you said as much in the first post), in which case the comma should go on the other side of noauto, it's a mount option, not an filesystem type. This mistake is present in your first config example too, which is possibly why that's not working either.

<HEADSMACK> You're right. I will edit my first post. Thanks.

Adding the nofail option is the general solution to this problem, but maybe I'm missing something...
