Update Precise drbd8-utils to 8.3.13 for the 12.04.2 release

[Simon Déziel]

According to https://lists.ubuntu.com/archives/ubuntu-devel-announce/2013-January/001003.html, Precise 12.04.2 will ship with kernel 3.5.0. This new kernel comes with DRBD 8.3.13 but the drbd8-utils package in Precise are still is at version 8.3.11.

Running a different version of the userspace utils and the kernel module is not recommended by upstream and gives such warning:

# /etc/init.d/drbd start
 * Starting DRBD resources DRBD module version: 8.3.13
   userland version: 8.3.11
you should upgrade your drbd tools!

Thank you for taking the time to report this bug and helping to make Ubuntu better.

I think this needs attention, so setting Importance to High. Usually SRU policy generally frowns on this kind of update, but it may make sense given that the kernel is being bumped. I appreciate you bringing it up.

I believe it will be possible to run the old kernel. Will the new drbd work with both?

[Jacob Smith (jsmith-argotecinc)]

I'm not the reporter but I am a daily user of DRBD on precise.

If someone is running the old kernel then they should use the matching older version of drbd8-utils.
So if the module in the kernel is 8.3.11 then the tools should be also or if the module is 8.3.13 then the tools should be 8.3.13 also.

I'm a total newbie about packaging but is there a way to make it so drbd8-utils version 8.3.11 is required to be upgraded if you go to kernel >= 3.5 and drbd is installed? And if you install/downgrade to kernel < 3.5 drbd8-utils must be downgraded to 8.3.11 at the same time if installed - through dependencies or something?

[Simon Déziel (sdeziel)]

Jacob, that is also my understanding, the userspace utility version must always match the DRBD module version.

[Numérigraphe (numerigraphe)]

As discussed in Debian[1], it's OK to use drbdadm 8.3.11 with module 3.8.13, and "This warning can be silenced if you set the following environment variable: DRBD_DONT_WARN_ON_VERSION_MISMATCH"

The only downside I know of is you won't have access to the newest command-line options. Reading the change log [2], that would only be the option "--force".

[1] http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=659353
[2] http://git.drbd.org/?p=drbd-8.3.git;a=blob;f=ChangeLog;hb=HEAD

So I suggest it's ok to not upgrade.

Sorry, I meant "OK to use drbdadm 8.3.11 with module 8.3.13" of course.

[Simon Déziel (sdeziel)]

Thanks for looking that up Lionel.

In 12.04.3 it now appears that the version 8.4.2 is in the kernel, but the userland tools have stayed static making the version gap grow. Could this be why when I run "service drbd start" it never kicks me back to the prompt until I hit Ctrl+C?

$ sudo service drbd start
DRBD module version: 8.4.2
   userland version: 8.3.11
you should upgrade your drbd tools!
 * Starting DRBD resources
DRBD module version: 8.4.2
   userland version: 8.3.11
you should upgrade your drbd tools!

[Jan Groenewald (jan-aims)]

Hi

Can you try linux-image-generic-lts-quantal or
linux-image-generic-lts-raring?
Those kernel versions will have different DRBD module versions.

Regards,
Jan

Yeah, actually just did 'sudo apt-get dist-upgrade' which took me to the lts-raring kernel and it looks happier. Thanks Jan!

I am still getting the version mismatch, but it seems to function properly now. Was that bug #1185756 I was running into? I was just parsing through that so maybe I'll comment over there that this resolved my problem and hopefully assist someone trying to parse that conversation.
