Hi All,
I prepared a small cluster with drbd and heartbeat with these
characteristics and configurations
Distribution Debian Etch with a minimum possible backports packets
kernel 2.6.25
drbd 8.0.11 built in kernel
heartbeat 2.1.3
the two machines are alessandra (master) lalla (slave)

the drbd devices are in /etc/fstab with noauto option
If I shutdown the master, the slave take over all of them without any
problem, it happens the same at reboot and if I type
/etc/init.d/heartbeat stop and start.
But if I unplug the network cable to simulate a fault in slave syslog I
found this:

and obviously does not start anything.
As it returns error "1",(lalla ResourceManager[8118]: ERROR: Return code
1 from /etc/ha.d/resource.d/drbddisk) I tried to search with google and
documentation drbd but I could not find anything, can someone please
explain what I do wrong?
thanks in advance and best regards
