I'd advise to update to 2.0-rc4 and 0.30.207
(IIRC, the latter one should be in broken^Wunstable :)

a single guest, or the /vservers (/var/lib/vservers
on debian) path?

should work fine with /dev/drbd0 mounted at /var/lib/vservers
but might give 'unexpected' issues on /var/lib/vservers/ha-vser42
(the common path for vservers is configured at build time, and
for debian this is /var/lib/vservers)

why the heck /etc/vservers? those are the config files,
and I doubt you want to put those into the drbd?

just means that your /etc/init.d/rc inside the guest
could not be executed by the default init style ...

also make sure that your debootstrap is not
buggy or some 'special' security is keeping
you from installing a 'working' debian system
with debootstrap ...
if those 'unusual' permission denied messages
(please check the kernel logs for more info)
remain after updating, please let us know as
it might be an issue which results from the
combination of drbd and linux-vserver ...
(i.e. we will look into it)
