First, thanks for your quick answer ! >I suppose this was the wrong entry? "Data" is not a valid device name. It is in a Virtualbox context. Once booted, "mount -a" mounts this partition to /mnt/Data, without any poblem. But it fails at boot, so I need to comment it, then modify /etc/fstab, then 'mount -a'.
>So mark it as "defaults,nofail" to tell that this isn't a critical partition. Thanks for the hint. I have tested that, and it works, the virtual machine is able to boot now. But when doing a "mount -a" right after the boot, I get that : root@blah:/home/folco# mount -a unknown mount option `nofail' valid options: [...] So I still have to modify ym fstab in order to use my partition. Why can't it be mounted while booting ?
