Hi,
Basically Ubuntu delivers back-ported kernels as part of the official
point releases, so DRBD gets upgraded too.
Usually all 8.4.x versions are compatible with 8.4.y tools, so I'm
suprised you have connection errors.
We did have a problem during the ubuntu 12.04 timeframe because Ubuntu
skipped from DRBD 8.3 to 8.4 - - eventually they patched the tools to
make them compatible with both.
It took them and quite a bit of testing to fix that, so by all means
please file a bug report against Ubuntu.
Anyway, one option you have is to downgrade to one of the previous
kernels (search for packages named "linux-.*-lts-.*").
Another option is to compile the tools on your own, it's quite easy on
Ubuntu.

Hi,
I installed two systems with Ubuntu 14.04 and updated them with all available
updates. The kernel version is 3.19.0. It has drbd kernel module version
8.4.5 and drbd8-utils version 8.4.4. Now the drbdadm commands complain about
the version mismatch "you should upgrade your drbd tools!" Even more
problematic is that the command drbdadm wait-connect comes with an error
message "error creating netlink socket". This command is used in the standard
start/stop script /etc/init.d/drbd.
Unfortunately Ubuntu has no update yet for the drbd8-utils package. I found
out that starting with drbd 8.4.5 the userland tools now have their own
repository and have new version numbers (e.g. 8.9.4). I could not find out
what version should be used for the drbd 8.4.5 version but it seems these
versions can handle several drbd kernel versions. So I downloaded the version
8.9.4 and built it. As I do not want to get too much unknown changes to my
Ubuntu configuration I just copied the drbdadm-84 and drbdsetup-84 to /sbin
and replaced the /sbin/drbdadm and /sbin/drbdsetup by soft links to the 84
versions. Now the wait-connect is not failing anymore. However the tool is
still complaining about the version difference: "please don't mix different
DRBD series.".
I wonder if my approach does not have side effects as I only replaced drbdadm
and drdbsetup.
I wonder when there will be a Debian/Ubuntu package available with the new
drbd-utils version which could be used on Ubuntu 14.04.
I wonder why the new version of drbd8-utils complains on the drbd kernel
module version while there is no drbd8-utils version 8.4.5 available.
Has anyone already some answers?
Regards,
Jacob van der Meulen
