From the mount output? That's the content of /etc/mtab, please compare
with /proc/mounts.

There's a little chance you have still the /dev/ubd/ folder.

It's possible that since the kernel mounts the root_fs, it's working anyway.
What you likely need to do is to recreate the devices you need like:
mknod /dev/ubd0 b 98 0
mknod /dev/ubd1 b 98 16
mknod /dev/ubd2 b 98 32
...
and so on (till ubd7) and/or (depending on your taste)
mknod /dev/ubda b 98 0
mknod /dev/ubdb b 98 16
mknod /dev/ubdc b 98 32
...
this can be scripted, but it seems I lost the script, however it's like
for ((i=0; i < 8; i++)); do
mknod /dev/ubd$i b 98 $[16*$i]
done
the second can be done too (with tr '0-9' 'a-i' to convert $i to the right
letter) but I'm too hurried to do it.
Bye
