I've got a pair of HA servers I'm trying to get into production. Here are some specs : Xeon X3210 Quad Core (aka Core 2 Quad) 2.13Ghz (four logical processors, no Hyper Threading) 4GB memory Hardware (3ware) Raid 1 mirror, 2 x Seagate 750GB SATA2 650GB DRBD partition run on top of an LVM2 partition. CentOS 5.2 2.6.18-92.1.6.el5.centos.plus DRBD 8.2 (drbd82-8.2.6-1.el5.centos) Kernel

Hello, We''ve been using Xen on several servers with direct-attached storage for a number of years. Now we''re looking to buy more Xen servers and re-purpose two of the older ones as SANs to hold the domU filesystems, in order to achieve redundancy and live migration ability. I''m looking for comments on our proposed design. SAN 1 - existing server w/ 4 GB, 2x

Hi, has anyone running Xen on top of iSCSI on top of a DRBD active/passive cluster? Have you tested failovers? Do Xen guests survive? thx, B. _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Hi All, I was hoping to pick someone''s brain about the best way of moving a Xen disk image (which has LVM''s inside of it) to a new block-device?  I have the target DRBD device ready but unsure what''s the best & safest way to do it. I was actually tempted to mount the Xen disk image in a dom0, and make it visible via loop devices and promote that DRBD node for

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

CentOS Errata and Enhancement Advisory 2005:1130-2 CentOS 4 i386 drbd / heartbeat - Enhancement Update (Extras Only) We are pleased to add drbd (with integrated heartbeat) to the CentOS extras repository. DRBD is a block device which is designed to build high availability clusters. This is done by mirroring a whole block device via (a dedicated) network. You could see it as a network raid-1.

Dear All, Previously we have used CentOS4.4 release with Supported Cluster Suite and DRBD 8.0.0 Active/passive (failover) We have build the DRBD 8.0.0 Source in CentOS4.4 Setup We have configured the DRBD Resource with default OS installed LVM (/dev/mapper/vgroot-LogVol00 and /dev/mapper/vgroot-LogVol01) Partition and its working fine Partition Tables are listed below

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, I have a server with Centos 5 + DRBD installed and is working fine, but when i run yum for udpate system show this error: Transaction Check Error: file /etc/drbd.conf conflicts between attempted installs of drbd-8.0.12-1.el5.centos and drbd82-8.2.6-1.el5.centos file /etc/rc.d/init.d/drbd conflicts between attempted installs of drbd-8.0.12-1.el5.centos and drbd82-8.2.6-1.el5.centos file

Hi, I've upgrade the kernel to the latest version (C5) and after the update the drbd is not being loaded at reboot time. My previous running kernel was 2.6.18-164.el5.

drbd-0.7.19 under kernel 2.6.17-rc4 is running on a primary node standalone. There are 8 resources in the same group. fsck.ext3 -fv is being run simultaneously on all of them. Each of the drbd devices are running on an lv, which all belong to a single pv. The actual "disk" is a hardware RAID connected via SCSI (i.e., the mpt driver). Five of the fsck finished their tasks
