Like so often answered on this list already: yes, you can mix versions like
that.

Yes, you always have to use the same version of tools and kernel module.

I assume you'd still have the package lying around...

disk not coming up

2008-12-04T10:27:07Z

hi..

I am running drbd 8.2.7 with xen 3.3 under centos 5.2 My drbd
resource name is guest01-disk. My entry in domU config file is

-----
disk = [ "drbd:guest01-disk,xvda,w", ]
-----

But if I try to run the domU, it says

----
[root@ha1 xen]# xm create centos1.cfg -c
Using config file "./centos1.cfg".
Error: Disk isn't accessible
-----

What is the problem here? I have also tested by changing the resource
to primary mode manully (drbdadm primary all) . still got the same
error.

Thanks
Paras.

Help Upgrading DRBD Versions

2008-12-04T09:46:00Z

In a previous thread it was suggested that I should upgrade to
drbd-8.0.14 from drbd-8.0.8 since I am required to upgrade my two node
cluster's kernels from kernel-2.6.23.8-63.fc8 to kernel-2.6.26.6-49.fc8
since the 2.6.26 kernel will not work with drbd-8.0.8. So that's what I
am going to do, but I am having difficulty on how to proceed. The
system is a intranet with mysql and http running on it that is highly
used. Heartbeat takes care of starting everything. I have searched for
a method to do this upgrade and have not been able to find anything I
can use. I would like to keep the original kernel and drbd kernel
module in place in order to reboot to original state if something goes
wrong. Will the following work:

On Backup node:
Download drdb-8.0.14
unpack
cd drbd-8.0.14/drbd
make clean
make KDIR=/usr/src/kernels/2.6.26.6-49.fc8-i686
make install
Reboot system to new kernel and new drbd.ko module and let heartbeat
control startup of services as required. Once that seems to work, fail
over to standby system and let it take over services and repeat the
above on the primary mode. Reboot primary and let heartbeat mount drbd
drive, assume services etc. Does this seem reasonable? A few
questions:

1.Can you run two different versions of drbd on each node (pri- 8.0.8
sec-8.0.14) until you completely migrate to the new version of drbd?
2.Do the drbd tools need to be rebuilt?
If so, won't it overwrite the drbd tools already there making it hard to
revert back?

I may be making this harder than it needs to be, but I inherited this
setup. That's why all the questions. Thanks for any help.

Hi Marcelo,

sorry about that. It was a copy'n'paste error. It is fixed now and you
should get the correct WMV file.

To upgrade cleanly I need an Ubuntu debian package. I didn't find one
on the net. So I assume, I've to build one.

I've searched through http://www.drbd.org/users-guide online since the
Ubuntu package I mentioned above didn't contain this users guide.
But even with a lot of help from old aunt Google ;-) I wasn't able
to locate the section you mentioned above. I admit, that I didn't
read the complete guide yet. Nevertheless please give a hint.

BTW:
The same excellent users-guide contains the following sentence:
"The DRBD source tree includes a debian subdirectory containing
the required files for Debian packaging, so you can simply issue
the following commands to build DRBD Debian packages: ...."
(cited from http://www.drbd.org/users-guide/s-build-deb.html )
Unfortunately it wasn't that simple:
I've first downloaded 8.0.14 and than in turn 8.2.7 and 8.3.0rc1 from
http://oss.linbit.com/drbd/
Neither of these tarballs included the promised debian subdirectory.

Is there a location where I can download a DRBD users guide matching
the software version I have? Or do I have to add this debian subdirectory
to upgraded original tarballs on my own again?

though it may blow up [again :(] if it finds something out of sync,
unless you also patch it with

you can place a "dummy" there,

Webinars now online for download

2008-12-04T05:44:19Z

Hello everyone,

I've added the Dolphin Express webinar from mid-November to our
on-demand webinars available at
http://www.linbit.com/en/education/on-demand-webinars/.

This webinar, and the preceding one on DRBD performance tuning, are now
also available for download in Windows Media (.wmv) format. This should
also play in totem, mplayer, or any other Linux based media player
provided you have the Windows audio and video codecs available.

I tried to transcode this to open formats too, but unfortunately haven't
as yet found a way to make it work in a sensible way. MPEG video grows
to over 200MB in size and any conversion attempt to ogg vorbis/theora
gets seriously messed up by ffmpeg. If one of you finds out a way to
convert this to ogg media format with acceptable quality, please share
your findings.

Happy viewing.

Cheers,
Florian

Interesting is that we have 7 DRBD resources. All of them (after HA and DRBD shutdown) become Unconfigured but drbd1 and drbd2 - they are Connected, Secondary/Primary, Diskless/UpToDate. You can see "receiver (re)started" for them in the log.
As linbit has removed the patches from their pages, I am curious whether this patch is the solution or not.
I tried to browse internet, there is no definite question.

I also found heartbeat 2.1.4 for CentOS taht should include this patch on:
http://download.opensuse.org

Does anyone has an experience with 2.1.3 patched DOPD or 2.1.4 version?

PS: I also can see following in the log file:
Dec 4 11:11:18 vsp11 kernel: drbd5: ASSERT( mdev->receiver.t_state == None ) in /home/buildsvn/rpmbuild/BUILD/drbd-8.2.6/_kmod_build_xen/drbd/drbd_main.c:2412
Does it actually mean anything?

Thanks,

Yes, it just works. A few details should be heeded though.

Please, always use the latest version. That's 8.0.14 for the 8.0 branch. You
might even consider upgrading to 8.2.7. The verify feature should be worth
it.

If you really want to do high availability, you should go all the way. I'm
speaking from experience. You don't want to hit one of drbd's known bugs when
you least need it. That is, when something happens and a node goes down.

If you leave out the diagnostic commands, you'll see that you end up with just
about the same commands as in the excellent drbd user's guide. The point is:
drbd just doesn't need a secondary. So if you leave it out, it'll just do
with one node.

Of course, the second node should already be in drbd.conf (don't know, if it
would work without). If you plan on running with one node only for some time,
you'll also want to set the wfc-timeout and degr-wfc-timeout to small but
positive values, so drbd wouldn't wait long for the second node to appear
when starting up.

Stefan

I had similar questions.
So I've waited a while for an answer from someone with more
experience in DRBD showing up, but that didn't happen until now.

So I'll try to explain it
in another way: When explaining DRBD to new people:
DRBD is often referred to as RAID-1 mirroring over ethernet.

So people already familar with todays Linux software RAID might
wonder, what is the equivalent of the software RAID command
mdadm --create --level=1 --raid-devices=2 /dev/md0 /dev/sda1 missing
within the context of DRBD.
The command above creates a degraded but running RAID-1 meta device
/dev/md0 which can afterwards immideately started to be used.
For example by formatting it with mkfs or by using it as part of DRBD.
Later you can add the mirror partition using
mdadm --add /dev/md0 /dev/sdb1

Yesterday I have for the first time tried to achieve creating a
degraded DRBD and hopefully I think, I succeded:
This is on a freshly installed Ubuntu 8.04.1 LTS which came with
a 8.0.11 DRBD package.

Of course I had to prepare the /etc/drbd.conf first.
To create the DRBD device (resource) on this single side server
(assuming the DRBD network is disconnected) I used the
following commands:
drbdadm create-md r0
drbdadm down r0
cat /proc/drbd
drbdadm -- ::::1:1:::: set-gi r0
drbdadm up r0
drbdadm primary r0
cat /proc/drbd
Afterwards I was able to mkfs.xfs /dev/drbd0 and mount it and
the output of /proc/drbd looks as such :

version: 8.0.11 (api:86/proto:86)
GIT-hash: b3fe2bdfd3b9f7c2f923186883eb9e2a0d3a5b1b build by phil@mescal, 2008-02-12 11:56:43
0: cs:WFConnection st:Primary/Unknown ds:UpToDate/DUnknown C r---

I have no idea, whether the procedure outlined above is advisable.
I was just tinkering around and hopefully found a way that works for
the first step. Today I shall see what will happen when I add the
second server.

nodes using drbd are not connecting after being disconnected

2008-12-03T21:16:55Z

I set up a heartbeat and drbd configuration that has drbd sharing a mysql database and heartbeat managing the cluster. The set up has two computers in the cluster, with 2 network interfaces. One interface is for the main network and the other is for the direct connection between the nodes in the cluster. My problem is after the direct connection is disconnected by simply pulling the cable out or shutting the machine down, the nodes become standalone and stay standalone even after the connection is started again by plugging the cable back in or turning the computer on.

So i'm not sure why the nodes never connect even after being online and having a networking connection. It seems like drbd just wont connect the nodes after the connection is interrupted just once. If someone has an idea on why this is happening or how to fix it their help is appreciated.

Thanks

DRBD take slowly sync over 1Gig-E

2008-12-03T19:36:42Z

Dear list,
I'm trying to build an Lustre file system with some fail-over nodes. I install drbd but realize it take very long time to do init sync.
Here is sum of my config:
CentOS5/drbd82
1 Gig-E, straight through cable connect via switch (iperf report 902MB/s) (I've tried straight cable direct connect but it seems slower)
I/O Scheduler: headline
sync rate set to:60MB

And here what I got:

[root@MGS2 ~]# cat /proc/drbd
version: 8.2.7 (api:88/proto:86-88)
GIT-hash: 61b7f4c2fc34fe3d2acf7be6bcc1fc2684708a7d build by root@..., 2008-11-19 06:52:49

I tried to Google. Seems many ppl have the same problem. I tried some solutions (run drbdadm adjust r0, tweak some config value, etc..) but the result was not changed.
I don't sure where is bottle-neck. Have any software to benchmark harddisk?

Thanks!

If I upgrade to 8.0.14 can I just do the following on the backup system:
cd drbd-8.0.14/drbd
make clean
make KDIR=/usr/src/kernels/2.6.26.6-49.fc8-i686
make install

Then reboot into the new kernel. Then repeat on the primary system. I
inherited this so I'm a little unclear how to proceed. By the way,
these systems are using heartbeat to mount the drbd device. Also, I am
trying to figure out a way to keep the old kernel stuff in place so I
can revert back if something fails. Do the tools need to be rebuilt?
If so, won't it overwrite the drbd tools already there make it hard to
revert back?

Thank You

I strongly recommend against anything older than 8.0.14.
(8.0.3 was early May 2007!)

right.
and a lot of other known bugs, a number of which are serious.
(Oopses and similar in failure handling branches,
raceconditions leading to deadlocks,
deadlocks in certain recovery scenarios or during resync).

I'm sure you are able to read changelogs,
they are referenced from
http://www.drbd.org/home/releases/

as for "simple use-cases, nothing fancy":
as long as nothing goes wrong, you probably won't notice any bugs:
"normal operation" is pretty easy.

but when something goes wrong, and the software stack that is supposed
to cover up for the failures gets stuck in some bugs known and fixed
since 18 month, you might be better off without any "HA" features.

drbd 8.0.8 will not work with 2.6.26.
try drbd 8.0.14.

8.0.x on pasemi/ppc

2008-12-03T15:00:25Z

Hello, list.

We are in the process of deploying drbd in a system based on the PASemi/PPC architecture (short term, for obvious reasons). The distro is MontaVista CGE 5.0. Their latest supported release of drbd is 8.0.3, which they have very recently assured us “is marked as supported for both LSPs in CGE5.0 and it is a production ready feature”.

Recent comments on this list seem to indicate that 8.0.3 has known issues with PPC (BigEndian bugs, etc.)

For very simple use-cases (simple Primary/Secondary, small partition size, nothing fancy), how imperative is it to move beyond 8.0.3 on the PPC release? Doing so entails stepping forward from the vetted MontaVista baseline, which we are reluctant to do.

Thanks in advance for your help and advice.

New Kernel - Can Not Compile DRBD

2008-12-03T14:26:05Z

I am running drbd-8.0.8 and was forced to install a new kernel on a
fedora 8 machine (local security policy). Before I booted off the new
kernel, I am trying to
compile and install the new drbd.ko module.

The following kernel packages are installed:
kernel-devel-2.6.26.6-49.fc8
kernel-2.6.23.8-63.fc8
kernel-devel-2.6.23.8-63.fc8
kernel-2.6.26.6-49.fc8
kernel-headers-2.6.26.6-49.fc8

I am running the 2.6.23.8-63.fc8 kernel right now.

I do the following:

cd drbd-8.0.8/drbd/
make clean
make KDIR=/usr/src/kernels/2.6.26.6-49.fc8-i686 (see output errors
below)

Doing make KDIR=/usr/src/kernels/2.6.23.8-63.fc8-i686 works fine and
creates the drdb.ko.

Any help would be great. I've done this on a redhat box with two
kernels
like above and it works fine also. By the way, The first error related
to Docbook does not seem to be an issue, I get this on other systems
also. I'm not sure where to go with this, I have a short lead time and
would like to stick to the same drbd version so I don't have to rebuild
the tools.

I enjoyed and learned from the webinar.

I tried connecting using Firefox (on Windows, I don't have audio on my
Centos) but it failed (empty screen after I "joined"). I switched to IE
and it installed some active-X component.

May be Webex changed their supporting software ?

Where can I find the webinar slides ?

boxes. 32bit Firefox with 32bit Java 1.5 failed because it could not find
some javax.crypt class.

I'm actually using 64 bit java, so I think that's the problem. I guessing that if i used 32 bit I wouldn't have a problem.

Cheers,

Odd. I've had zero issues connecting to Webex (both presenting and
attending) on several Ubuntu versions, several Java incarnations, and
multiple Firefox releases in over a year and a half.

Those of you who can't connect to or use Webex, are you on 32 or 64 bit
Java?

You're not being serious, are you? Do you (or does someone else) have a
serious Webex alternative to recommend? Huddle perhaps? Dimdim? We're
open for suggestions.

Cheers,
Florian

Firefox was able to display the form, but I only saw that 100% bar and then nothing happened.

I just wasted a complete hour trying to join the webinar because the webex
site is so broken, that konqueror does not even recognize the join form as
HTML and displays it as text/plain instead. After saving that file to disk,
changing the source and fixing Java, the applet would load and stay at 100%

Please! Is there really no other way to do this? Even uploading a video to
youtube and using the comments sounds more attractive than that.

I would have really liked to attend that webinar as I would have liked to see
the others. What remains is the small hope that the promised usable videos
will appear eventually...

yep.
accidentally that tarball lacks the pre-build manpages.

we tar'ed it up again, and re-uploaded,

drbd-8.3.0rc1.tar.gz, 365236 Byte, 2008-12-03 10:23 UTC

yes, on both 32bit and 64bit.

then go fix it.

or wait until someone (maybe LINBIT?) fixes that first.

I am certain that the current code base cannot support more than 32 TB
without major changes.

I am currently unsure whether it might support up to 32TB (though
probably on 64bit kernel only) with only minor code changes.
we are looking into that.

Yes, usually we have pre-build man pages in the distribution tar.
I did not realized that they were missing in drbd-8.3.0rc1.tar.gz
until your post.

I just replaced drbd-8.3.0rc1.tar.gz on oss.linbit.com with a
tarball that includes the pre-build man pages.

342829 drbd-8.3.0rc1.tar.gz (old one, with out man pages)
365236 drbd-8.3.0rc1.tar.gz (new one, with pre-build man pages)

For a heartbeat2 setup, you'd have something like

<nvpair id="some_id"
name="device" value="/dev/drbd0"/>
<nvpair id="some_directory"
name="directory” value="/postgres"/>
<nvpair id="some_fstype"
name="fstype" value="ext3"/>
<nvpair id="some_options"
name="options" value="rw,noatime,quota=wharrgarbl" />
[tedious XML snipped]

...in the <primitive> tag for your OCF resource. drbd shouldn't come into
the picture at all; the drbd device should just look like a block device
which happens to have an ext3 filesystem with quotas on it. (And what in
the name of the Flying Spaghetti Monster were the heartbeat people thinking
when they came up with that annoyingly verbose config file format?)

Using quotas on a ext3 file system layered on a drbd device

2008-12-02T12:09:22Z

All,

I have a typical drbd setup, two identical Centos servers with a dedicated drive in each that handles the drbd mirroring. I use an ext3 file system on the drbd drive. What I’d like to do is enable quotas on this file system. We have a postgres database which will get the lion’s share, plus a smaller space for people to upload and download files. We don’t want the people space to fill up the drive and lock up postgres. Since there is no entry in fstab due to the use of Heartbeat’s Filesystem OCF script, how do I enable quotas on this file system? Has anyone done quotas on a drbd drive’s file system?

Thanks,

Doug Knight

Drbd 8.3.0 rc1 rpm build failing

2008-12-02T09:43:43Z

I've grabbed the latest drbd-8.3.0rc1.tar.gz from the

I've tried building the rpm using

make rpm

but it fails as follows:

I'm trying to build this on CentOS 5. This is a dedicated build system
on which I have built rpms before successfully.

Looks like it's complaining about documentation files that are missing,
in the documentation subdir, there are sgml files.

EDIT: I figured out I need docbook-utils and did a make doc in the
documentation subdir, then rebuilt the rpm successfully.
