similar to: using DRBD VBDs with Xen

Hi. The short story... Rush job, never done clustered file systems before, vlan didn't support multicast. Thus I ended up with drbd working ok between the two servers but cman / gfs2 not working, resulting in what was meant to be a drbd primary/primary cluster being a primary/secondary cluster until the vlan could be fixed with gfs only mounted on the one server. I got the single server

Hi guys! I can?t find an answer in google, so my last hope is this mailing list. Story. I have two servers with same arrays. Servers connected by DRBD. I used ocfs2 as file system, also I used NFS4 to access to the ocfs2 drive. I do not have any idea, but the allocated descriptors in /proc/sys/fs/file-nr increasing every time while drive accessed. So after some time allocated descriptions over

Hi, Sorry for the need of the long winded email. Looking for some answers to the following. I am setting up a xen PV domU on top of a LVM partitioned DRBD device. Everything was going just fine until I tried to test the filesystems in the domU. Here is my setup; Dom0 OS: CentOS release 5 (Final) Kernel: 2.6.18-8.1.4.el5.centos.plusxen Xen: xen-3.0.3-25.0.3.el5 DRBD:

Hello, We have successfully implemented a 2-node HA Xen cluster with DRBD, LVM and heartbeat, that can do live migration. I wrote up some details here: http://te.to/~ts1/xen_cluster.html I''d like to say thank you to all the people writing these great software. -- Takeshi _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com

Hi We've got drbd going between 2 nodes:) ATM there is un-partitioned space on each node but (we think) they are syncing OK. It looks as though it has synced the whole partition (2GB) from the primary node 1 to the other node: node 1 smb1:/home/steve # cat /proc/drbd version: 8.4.4 (api:1/proto:86-101) GIT-hash: 3c1f46cb19993f98b22fdf7e18958c21ad75176d build by SuSE Build Service 1:

What is the best way to compile xen on centos 5.3? Also I need to able to kmod Yum kmod-drbd with the new version of xen. I belive that if I want to use xen 3.4.1 I have to re compile kernel right?

I''ve been brainstorming... I want to create a 2-node HA active/active cluster (In other words I want to run a handful of DomUs on one node and a handful on another). In the event of a failure I want all DomUs to fail over to the other node and start working immediately. I want absolutely no single-points-of-failure. I want to do it with free software and no special hardware. I want

In a prior message I documented my woes in getting an NFS_ROOT xen going. I haven''t resolved those yet, want to try a different tack at this: If the group were to recommend a path of least resistance to showing migration/live migration, which configuration would it be?

Hello, I have a couple of Dell 2950 III, both of them with CentOS 5.3, Xen, drbd 8.2 and cluster suite. Hardware: 32DB RAM, RAID 5 with 6 SAS disks (one hot spare) on a PERC/6 controller. I configured DRBD to use the main network interfaces (bnx2 driver), with bonding and crossover cables to have a direct link. The normal network traffic uses two different network cards. There are two DRBD

Hey all, This utility (from Qemu) might be useful to anyone who has multiple partitions on a file-backed VBD and wants occasionally to mount them in dom0. http://www.dad-answers.com/qemu/utilities/QEMU-HD-Mounter/lomount/ You can tell it what partition to mount out of the file and it sorts out the offsets, etc. by parsing the partition table. This allows you to get around the loop
