similar to: Xen 4.0 - what solution?

hi folks, i have now a squeeze box, 2.6.39.3, xen 4.2 unstable running. for a remus sync, I need the disks (lvm) to besynced which I wanted to do with drbd protocol D. I downloaded the source from git://aramis.nss.cs.ubc.ca/drbd-8.3-remus drbd-8.3-remus page and made: (http://remusha.wikidot.com/configuring-and-installing-remus) git clone git://aramis.nss.cs.ubc.ca/drbd-8.3-remus drbd-8.3-remus

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

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

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? [ 887.648072] block drbd1: Local backing block device

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, Does anybody have this problem when try to migrate DomU : Error: /usr/lib/xen/bin/xc_save 22 6 0 0 0 failed I use xen 4.2.2-pre compiled from sources and my machine is Ubuntu 12.04 Linux with kernel 3.2.0-29-generic. Its working perfectly, even remus with drbd support migration was running successfully before. However today after I kill the remus process with command pkill -USR1 remus

Dear List, i''m experimenting with remus with the following setup. dom0: - Debian Squeeze - Jeremy''s 2.6.38.48 kernel - xen 4.1.2 recompiled from sid - DRBD for block device backend domU - Debian Squeeze Remus is working fine unless i try to give more than 1 core to the domU. Here''s the error from remus when i''m trying to enable it for an SMP domU:

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, We''re trying to use remus for some fault tolerance experiment. We followed the instructions and finished installing and configuring Remus on Xen 4.0.1. We succeeded when running a very simple Linux script on domU: we saw the same domain created on the backup machine. But when we tried to run a Java database benchmark, the dom0 OS crashed on the primary machine. Does anyone have any

I noticed recently that there is no real easy way to get the kernel driver for blktap working in mainline. I''ve pulled down the source from Daniel Stodden''s linux git tree on xensource, but it looks like it''s for debian and I''m running Fedora 14, so I''m trying to sort it out. I run the 3.1.x kernel and don''t want to go back to the 2.6.32 that

Dear All, I''m totally new to DRBD + XEN over iSCSI but I need to configure this scenario in order to buy the right hardware. Our department will provide us with an iSCSI target which will be replicated in its own to a secondary iSCSI SAN (probably they will use DRBD). This target will be used, in our ideas, to replicate our own iSCSI san, that we are going to buy. We will probably

Hello, I am trying to set up a Xen/Remus test configuration on AMD64 hardware (HP DL380 G6) under SuSE 10.1 and am having trouble. I was able to run and configure the Xen 3 that came with SuSE fine, but as far as I can see, I have to use Xen 4 to get Remus. I managed to build Xen 4 from source and it seemed to install, but I am not sure how to get the proper kernel and/or initrd files in place

Hi, I''m doing my master research and I need to adapt remus code. Now... I wanna get the checkpoint size (memory + disk) on each period. Does someone know what function does this? I think some *fd *object''s function in remus code could just get the memory size. Does someone help me? Thanks _______________________________________________ Xen-devel mailing list

Hi guys, I''m running Xen 4.2.1, compiled manually so I can play with Remus and DRBD, running on Ubuntu 12.10.

Hi, I would like to announce the first release of Kemari, an open-source virtual machine synchronization mechanism for fault tolerance. It offers a feasible approach to fault tolerance that does not require the use of specific hardware or modification of applications/OS. Kemari aims to keep VMs transparently running in times of hardware failures. It transfers the state of the primary VM to the
