Bug in DRBD causes split-brain, already patched by DRBD devs

You can't compile drbd because of bug #285. The solution is to patch idr.h to the old content, I explained how in the thread about this bug (at posting #18).

Many thanks richardvd, after reboot i see the module DRBR 8.4.2 on the kernel. :p

Also on my lab I have recently installed DRBD 8.4.3 on PVE 3.0 since his tar.gz, but ...
... is possible install it from the git? or make the ".deb" files since his tar.gz? and how do it?

Best regards
Cesar

Yes, for PVE 2.3 it is explained in the second half of the same posting. Just follow the steps.

If you ask about 3.0, I don't know.

Thank you very much richardvd and all people who has the patience to explain me. In this forum you are people wonderful.

Now i have my two nodes with DRBD 8.4.2 online, and will wait one day to see if you lose the connection.

About of DRBD 8.4.3 on PVE 3.0 is the same work, on my lab i have installed DRBD 8.4.3 on one node for now, i am sure that you don't will have problems.

Please let me to do one question: How can i to make ".deb" files for install the DRBD 8.4.3 files on PVE 2.3?

Best regards

If you follow these steps then it should create everything you need for drbd-8.4.3 on PVE 2.3.

Thanks richardvd, but I want to create the files:
drbd8-module-source_8.4.3-0_all.deb, and
drbd8-utils_8.4.3-0_amd64.deb

So, if i have these files with me, i will can install on several computers without need to download of git o linbit and compile it. The idea is only for gain time.

A hug
Cesar
 
These files are generated if you follow the steps indicated. You will find the .deb files in /root/drbd.

More details please. What do you do exactly and what's the output?

Are you using a dedicated network port for DRBD?
If not, then network congestion is a likely source of the issue here.

Also, the error seems to indicate some sort of data corruption, maybe you have a bad nic/switch or ram.

A simple google search took me to this page:

http://www.drbd.org/users-guide/re-drbdconf.html

Go to the section titled "Notes on data integrity"
I think your answer is to this problem is there.

Hi e1000 and all people

In the mailing-list of DRBD tell me that: "the in-kernel realtek drivers of the 2.6.32 kernel were known to cause troubles. I still have to replace them for optimum stability. try to install the current version of the driver from realtek ot switch to Intel-NICs"

So, I don't know how do it, and in this link http://packages.debian.org/squeeze/firmware-realtek say for download the drivers for Realtek and Debian, but neither know if these drivers are more modern that the pve kernel.

And to make matters worse, in this country (Paraguay) is not easy to buy another brand of NICs.

Can you or anyone helpme with this problem.

Append - Re-Edit: The model of NIC is "RTL8168E" and lshw shows "firmware=rtl_nic/rtl8168e-2.fw"
and the link of debian shows (among other models):
* Realtek RTL8111D-1/RTL8168D-1 firmware (rtl_nic/rtl8168d-1.fw)
* Realtek RTL8111D-2/RTL8168D-2 firmware (rtl_nic/rtl8168d-2.fw)
* Realtek RTL8168E-1 firmware (rtl_nic/rtl8168e-1.fw)
* Realtek RTL8168E-2 firmware (rtl_nic/rtl8168e-2.fw)
* Realtek RTL8168E-3 firmware (rtl_nic/rtl8168e-3.fw)

Best regards

Why did you replace git:// by http:// ?
It is not the same. Replace your git clone line by this and try again:
Code: 
git clone git://git.drbd.org/drbd-8.4.git
 
I have downloaded the drivers of Realtek from his official Web Portal:
http://152.104.125.41/downloads/dow...d=5&Level=5&Conn=4&DownTypeID=3&GetDown=false

But when i execute (after of unpack the file):
shell# ./autorun.sh

I get this message:

8.035.00 works with the current pve kernel. If you provide me with an email address I can send a tarball of it to you.

You're a great buddy

Please, before let me to do a questions:
1- Did you tried it or did they say?
2- Your source is http://download.hetzner.de/drivers/r8168-8.035.00.tar.bz2 ?
3- The latest version is 8.036.00 with update time 2013/6/11, can you give me access to this version?

because i tried with this (link above of hetzner.de) and i get this message:
make -C src/ modules
make[1]: Entering directory `/root/aleman/r8168-8.035.00/src'
make -C /lib/modules/2.6.32-20-pve/build SUBDIRS=/root/aleman/r8168-8.035.00/src modules

1) I have tried it
2) My source was downloaded from realtek
3) I don't have latest driver source since I recently have replaced all my realtek nics with intel nics. Using intel nics and your life gets so much easier;)
