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

hi all, coming finally to the end, remus, all works except some questions? 1) I protect 1 guest (remus -i 100 server01 10.41.10.42). how can I protect 3 guests? like to execute 3 commands like remus -i 100 server01 10.41.10.42 remus -i 100 server02 10.41.10.42 remus -I 100 server03 10.41.10.42 2) how can I see if remus works? are there any douc''s for command line switches? 3) does

Dear all, I am quite new in this virtualization area. I am want to do some experiment with live migration using xen. However, I got problem since my server didn''t support VTx.

Dear all, Again, I have some question here and I hope some one have experience how to do it. I have Xen 4.2.1 installed from sources and working with XM toolstack. I will use this xen in order to run Remus high availability with DRBD. Does any one know about openvswitch integration with xm toolstack, since Xen wiki only confirm XCP have natively support openvswitch

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

Olle ?) aiming to unify logging, eventing, monitoring (AMI, SNMP, ...) APIs. I think that thread occurred when it was decided to include a version number in Manager interface. I agree this is an interesting idea ... The use case that made me ask this is here : I've got a running system which is working ok up to a moment it stops to dial out on ISDN-BRI spans (incoming calls are ok). When

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 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.
