Good morning everybody.
I'm new in the list, so forgive me if topic is outdated.
I'm using drbd 8.0.4 with 2.6.14 kernel from WindRiver. When I try to
setup drbd (drdbadm up all) the userland tools cannot communicate with
driver, as the kernel module drbd.ko generates an oops:
How can I verify if my kernel configuration is suitable for drbd?
Thanks in advance,
Maurizio
