Hi,
Thanks for the answer.

Yes, you're right, /proc/drbd says...
version: 8.3.11 (api:88/proto:86-96)
srcversion: 2D876214BAAD53B31ADC1D6
...while drbdadm says: version: 8.3.13 (api:88)
Do they have to match exactly? If so, any suggestions on what to do when
the OS distribution provides mismatching versions?

Our device stack is:
SATA -> MDRAID6 -> LVM2 -> DRBD (-> EXT4 -> XEN)
>> kernel: [ 9832.457733] block drbd6: data-integrity-alg: <not-used>

Is it just for better debug output, or should we expect corrupted data
with the kernel/userspace version discrepancy? I need to get this
working so should I get new sources from linbit and compile the modules
and tools myself? If so, is 8.4 or 8.3 recommended?

version: 8.3.11 (api:88/proto:86-96)
