Hi,
I am using DRBD version 8.4 on CentOS6 and having some issues in
understanding the replication mechanism.
Configuration Details:
-
[root@centos6 ~]# drbdadm --version
DRBDADM_API_VERSION=1
DRBD_KERNEL_VERSION_CODE=0x080407
DRBDADM_VERSION_CODE=0x080905
Hi to all
About of my problem of DRBD replication, please see this link:
http://drbd.10923.n7.nabble.com/Replication-problems-constants-with-DRBD-8-3-10-td17896.html
After, I made these changes:
1- Changed the drbd version to 8.4.2
2- Changed the realtek NICs for Intel PRO/1000 Pt Dual Port

Hi Lars Ellenberg
*Into this topic/thread, you said me that:*
With special purpose built fencing handlers, we may be able to fix your
setup so it will freeze IO during the
disconnected period, reconnect, and replay pending buffers, without any
reset.

Hi to all people
Excuse me if I ask a question from rookie
But 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
Realtek NICs are garbage... For an entertaining read, look at the header
of the kernel drivers. The author goes into detail on why they are such
crap. In my own testing, they do not provide their advertised speeds and
their jumbo frame support is laughable. It's not a question of newer

Thanks Luca Fornasari for your answer
Please let me tell you that:
1- I use direct conection for DRBD (NIC to NIC)
2-I don't have changed my sysctl.conf file, this file are as the original
instalation.
3- Making tests, first I change the directive net data-integrity-alg sha1 to

Thanks Digimer,
This is what I understand even with identical hardware in back-to-back
Thanks to all people for your patience, and especially to Digimer for explain
and share their knowledge.

I think the fastest way to change some hardware is to switch the bond to
the second set of interfaces ...

Hello everyone
*Please Urgent, my servers are in production*
I am in a serious problem and need help
*My my scenario*
- I have two workstations ASUS P8H77-M PRO with Intel core I7, Proxmox VE
2.3, DRBD 8.3.10, LVM on top of DRBD
- 2 NICs Realtek RTL8111/8168 PCI-E of 1 Gb/s in bond round robin
First thing that jumps out at me is that the round-robin bonding is not
supported. Only mode=1 (Active/Passive) is. Secondly, you do not have
fencing, so when the network error occurred, you got a split brain;

Thanks again digimer for your answer
I read your link, but with DRBD i use direct connection to the NICs and not
over switches. But as I'm in front of a problem, I will try in mode
active-backup.
But if you can give me links for this case I will be very grateful
