Dear DRBD users,

I know that this question has been answered a number of times, but
none of the answers I have found could solve my problem.
I am using drbd with 2 volumes, and when I try to add a third one, I
get the error in the subject (but the mentioned device node exists of
course). Specifiing a minor_count parameter, or even raising the minor
count default value in the source, and recompiling the module didn't
help either.

Software versions:
drbd: version: 0.7.21 (api:79/proto:74), compiled as module
the kernel is a debian-patched 2.6.8 kernel.
The system is an IA64 server, but both the kernel and user space sw are 32 bit.

The exact command & parameters which give this error are:
drbdsetup /dev/drbd2 disk /dev/vol00/mail internal -1 --on-io-error=panic

I am waiting for your suggestions.

Thanks in advance,
Miklos Balazs
