Hello, I have been playing around with Remus on Xen 4.0.1, attempting to fail-over for an HVM domU. I''ve run into some problems that I think could be related to tapdisk2 and its interaction with how one sets up Remus disk replication in the domU config file. A few things I''ve noticed: -The tap:remus:backupHostIP:port|aio:...

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'...

Hi, i already tried to ask this and did not obtain any answer. Is remus is supported in Opensuse Linux actually ? Regards _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

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-remu...

...formum might be the wrong one for my question but maybe the last and/or only one what can give me my questions answered. i know how to setup and run a xen infrastructure, i have several server in production. the new thing is, that i started to use the debian squeeze, cause of the native suport of remus (kernel support), as everyone say: hardware ******* hp dl 380, 48gb ram, 8 tb disk, 2 processors software ****** debian squeeze amd64, latest upates xen 4.0.1, via aptituse lvm guests ***** windows 2008r2 x64 windows 7 x64 windows xp x86 debian lenny i have an identical second hardware bo...

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-dev...

...g 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 Jeremy has, which has the blktap driver in it. Is there anything out there that will patch a 3.1.x mainline kernel to include the blktap driver? I want to try out drbd/remus, but it''s not going anywhere at the moment. Thanks. Mike

Hello, we are using debian, xen 3.x and a iscsi-storage with ext4 as filesystem. Heartbeat is used for xen-ha. Now we like to change to xen 4 and remus. The iscsi SAN is available on active-Dom0 and backup-Dom0. I don´t have to use the disk buffering, as I understand remus right, because the file system on both machines is the same. With ext4 we don´t had problems at the xen3-Cluster on live migration. Also on tested hardware crashes. Is it...

hi xen cracks :-) i managed sucessfully to install xen4 on a debian 6.0 squeeze amd64 box, running 3 hosts windows 2008r2 server and 1 host squeeze. i use a hp server dl 160g6 dual processor with 48gb ram and 2 tb disks with sw raid 1. i have an indentical hardware box to setup remus. now, the problem is, i cant find remus on my box, like i saw it in several descriptions: /usr/bin/remus! is there anyone here who knows how to install/setup remus with the described enviroment? folks, answers are really aprechiated :-) thanxs to all ... __________________...

Hello everyone, I''ve managed to configure and start Remus. However, it works only while the protected server is not loaded. As soon as I start a memory-intensive server application, the stream of Remus messages stops, leaving me with an error message. I think the message is not always the same, but here is what I''ve got from the last run: PR...

Hi, I am trying to understand and change the network buffering that is being used by Remus, the HA solution present in Xen. From what i understood from reading the code, Remus calls the postsuspend method of the BufferedNIC after it suspends the domain that sends TC_PLUG_CHECKPOINT message and start the buffering and then calls the commit method of BufferedNIC after it gets the acknowled...

This patch series adds support for network buffering in the Remus codebase in libxl. Changes in V3: [1/5] Fix redundant checks in configure scripts (based on Ian Campbell''s suggestions) [2/5] Introduce locking in the script, during IFB setup. Add xenstore paths used by netbuf scripts to xenstore-paths.markdown [3/5] Hotplug scripts s...

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...

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 sur...

Hi everyone I've installed package xen-hypervisor-4.0-i386 (and related) on debian squeeze, using the available debian packages. According to the Remus website http://nss.cs.ubc.ca/remus/ and xen websites, remus (binary) should be available since xen 4.0.1. I can't find the binary though. I have installed: ii libc6-xen 2.11.2-7 Embedded GNU C Library: Shared libraries [Xen version] ii libxenstor...

...ip route add default via $P2 dev eth0 table openvpn1 eth0 is FW''s not default external NIC. I have in use very similar iptables rules for my email server (TCP ports) and etc. Everything works fine. What I''m doing wrong with marking/routing the UDP port? Regards Remus

Hello guys, First of all I need remus support for a Debian 6 system (kernel 2.6.32-5 : Xen-4.1.1). Debian-customized kernels don''t actually support remus. There''s a patch here: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=608988 that suggests adding the support for upcomming releases of the kernel, yet only in the...

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 http://wiki.xen.org/wiki/Install_Xen_4.1.4_with_Remus_and_DRBD_on_Ubuntu_12.10but I used xen 4.2.2 as my hypervisor with DRBD 3.8.11 remus support from this link http://remusha.wikidot.com/local--files/configuring-and-installing-remus/drbd-8.3.11-r...

Dear all, We are struggling to install xen 4.0 with remus on Ubuntu and debian 6.0. Can you suggest some source that can help us or some distro which has inbuilt feature.
