Hi, First of all, I'm new to ocfs2 and drbd. I set up two identical servers (Athlon64, 1GB RAM, GB-Ethernet) with Debian Etch, compiled my own kernel (2.6.16.20), then compiled the drbd-modules and ocfs (modules and tools) from source. The process of getting everything up and running was very easy. I have one big 140GB partition that is synced with drbd (in c-mode) and has an ocfs2

Dear all, I have sent this problem earlier but maybe its not detail, here I try to write more detail. I hope anybody can help me to point out the problem. First of all I used Ubuntu 12.04 x64 both for domain0 and domainU with modification to run under xen hypervisor and work with remus. I follow and configured the remus with this notes

Dear all, I have installed DRBD 8.3.11 compiled from sources. However the backend block will freeze if there is high IO load. I use Remus to support high availability and checkpointing is controlled by remus for each 400ms. If I check the Iostat I got the idle CPU will decreasing extremely each checkpointing and when its reach 0% of idle cpu the local backing device will freeze and damage the

Hello List, i am running Debian Squeeze and i installed DRBD, 3.2.0-0.bpo.4-amd64 and Xen4.0 from the Backports.

Hi, I would normally post this to the drbd list but it so low traffic/low volume (plus Austria might be asleep right now) I figured i'd ask someone here in case they have gotten drbd working on centos. Right now my system says i'm only the 971st person to even install it... It's been out for years, so likely this just means version 8. But you'll only see a couple of posts

Hi all, I don''t know if my question doesn''t related to xen at all, how ever I am trying to use DRBD as my disk replication when I ran Remus. However when I run remus sometimes my Dom-U will be freezing. I see the log file and it seem caused by drbd frozen : 875.616068] block drbd1: Local backing block device frozen?

Hi All, We have a somewhat serious issue around NLB on Windows 2012 and Xen. First, let me describe our environment and then I''ll let you know what''s wrong. 2 X Debian-squeeze boxes running the latest provided AMD64 Xen kernel and about 100GB of RAM. These boxes are connected via infiniband and DRBD is running over this(IPoIB). Each VPS runs on a mirrored DRBD devices. Each

Hi List, i'd like to share with you what happened yesterday. Kernel 2.6.36.1 ocfs2-tools 1.6.3 (latest). I had an old OCFS2 partition created with a 2.6.32 kernel and ocfs2 tools 1.4.5. I unmounted all partitions on all nodes in order to enable discontig-bg. I then used tunefs to add discontig-bg, inline-data and indexed-dirs. During indexed-dirs tunefs segfaulted and since then, fsck

Hi, I have been trying to create a xen HVM Centos4.4 image on centos 5 with a DRBD filesystem installing from DVD. However I get an IO error on the filesystem during the centos installation process which then aborts. The DRBD filesystem seem to be setup correctly and is functioning as a block device as I can mkfs -t ext3 /dev/drbd1 read and write without error. If I replace the disk

Hi, I would like to know if somebody can point me out how to configure several DomUs in a private LAN (for example 192.168.100.0/24) and one DomU with two interfaces (one - 192.168.100.0/24 and two - internet). So far I have enabled in xend-config.sxp: (network-script network-route) (vif-script vif-route) My config files have: /mnt/VM/1.cfg:vif = [''ip=192.168.1.3'']

Hello everybody, I am in the process of setting up a really cool xen serverfarm. Backend storage will be an LVMed AoE-device on top of DRBD. The goal is to have the backend storage completely redundant. Picture: |RAID| |RAID| |DRBD1| <----> |DRBD2| \ / |VMAC| | AoE | |global LVM VG| / | \ |Dom0a| |Dom0b| |Dom0c| | |

Hi all, I want to do live migration of domains using DRBD block devices for synchronisation between the two Xen hosts with Xen 2.0.7. I''ve written a script ( block-drbd ) which binds / unbinds DRBD devices for specific domains (with DRBD, only one host can write on a drbd device at the same time). This script sets the current host as master (bind) or secondary (unbind) in a DRBD

Hi everyone, I´m using Citrix XenServer with DRBD. But something went really wrong, so I need a fresh Install.My only question is, how can I mount the DRBD partition? It is /dev/drbd1 , but if I try to mount it, I need to provide the filesystem type. Does anyone know what I have to do? I only need to copy some data from it, it doesn’t matter if it will be destroyed. I tried GFS as filesystem
