I want to configure DRBD in my Rackspace cloud servers. While following the online guides, I can see that the kernel should be updated that support drbd. When I check in the servers, I can see drbd module is not included in my server kernel.
root@test1:~# modprobe drbd
FATAL: Module drbd not found.
I have tried to update the kernel module by apt-get upgrade but it is showing upto date.
root@test1:~# apt-get upgrade
