Install on vps give root mount error

[martijn-pf]

Installation:
Netbooted a system and did a zcat image| dd of=/dev/vda bs=16K
This went fine, but then it ends with:

ROOT MOUNT ERROR:
If you have invalid mount options, reboot, and first try the following from
the loader prompt:

set vfs.root.mountfrom.options=rw

and then remove invalid mount options from /etc/fstab.

Loader variables:
vfs.root.mountfrom=ufs:/dev/ufs/pfsense1
vfs.root.mountfrom.options=ro,sync,noatime

Manual root filesystem specification:
  <fstype>:<device>  Mount <device>using filesystem <fstype>eg. ufs:/dev/da0s1a
                      eg. cd9660:/dev/acd0
                      This is equivalent to: mount -t cd9660 /dev/acd0 /

?                  List valid disk boot devices
  <empty line="">      Abort manual input

mountroot>?
List of GEOm managed disk devices:
iso9660/CDROM acd0t01 acd0
Then I tried "ufs:/dev/ufs/acd0 ufs/dev/ufs/acd0t01 but I still can find the root device.

How can I get this working?</empty></fstype></device></device></fstype>

instead of ufs:/dev/acd0 try exactly this ufs:/dev/da0s1a. type the highlighted phrase as it is infront of the mountroot>.

That's unlikely to work since /dev/da0 is not a listed device.

You have copied the image to /dev/vda but that is also not a GEOM recognised device.
The only thing recongnised is a CD-ROM drive. Is that the virtual drive from the hypervisor?
