** Description changed:
Request for SRU:
[Impact]
- DRBD will not work (hang) on fresh install using Ubuntu 12.04.3 media, and
will stop working on sites where the Raring Enablement Stacks is manually
installed
+ DRBD will not work (hang) on fresh install using Ubuntu 12.04.3 media, and
will stop working on sites where the Raring Enablement Stacks is manually
installed as the API between older and newer drbd kernel modules has changed.
+
+ [Fix]
+ The current version of drbd8 utils in Saucy/Raring can be compiled with
legacy utils enabled (basically drbdadm and drbdsetup) and automatically
switches to use the legacy version when an older kernel module is found.
Comparing the code of those two legacy tools showed them to be mostly the same
(except some things that actually look like bug fixes).
+ I only found two small issues, one was the init.d script which was changed to
use a new command of drbdadm to activate resources. This would fail if drbdadm
fell back to the legacy version. So I picked the shell function that the
current util uses and verified that this still works with the new binary.
+ The other problem was the default config file which contained a new open
which would cause the legacy util to fail. It does not seem to be a required
one in the new tools to commenting it out by default seems to work in both
cases, too.
+ Lastly (this did not seem to be a real issue) the legacy tools claimed to be
a version 3.8.10 while the the code really looked like the 3.8.11 version we
have in Precise. Since that also matches the version number of the drbd module
in Precise I modified the legacy tools version to be 3.8.11.
+
[Test Case]
- Install the Raring kernel in Precise, install/configure DRBD: you get "No
response from the DRBD driver! Is the module loaded?".
- [Regression Potential]
- The current drbd8-utils must not be upgraded (it's needed for Precise &
Quantal kernels), a new package must be created for the DRBD 8.4 utils.
+ Install the Raring kernel in Precise, install/configure DRBD: you get "No
response from the DRBD driver! Is the module loaded?". With the proposed
backport the mirror continues to work. Only for switching back to an older
kernel a special procedure must be followed (see comment #21):

I've just installed linux-generic-lts-raring on 12.04.2 and my drbd device
stoped working.
Seems like drbd8-utils is not compatible with DRBD 8.4 in Kernel 3.8.
I see that we can't upgrade the package since this would break compatibility
with the older Kernels in Precise.
But since the new Plans for the LTS-Enablement Stack [1] there should be
a package like drbd8-utils-lts-raring. And the dependancies should be
resolved automatically with apt.
kind regards
