Does anyone have OCFS2 running with the "Red Hat Cluster Suite" on RHEL? I'm trying to create a more or less completely fault tolerant solution with two storage servers syncing storage with dual-primary DRBD and offering it up via multipath to nodes for OCFS2. I was able to successfully multipath a dual-primary DRBD based GFS2 volume in this manner using RHCS and GNBD. But switched

I've googled for this, but everything I find tends to talk about cluster and doesn't give an example close enough that I can figure this out. I have read the Red Hat Cluster Suite Configuring and Managing a Cluster <http://www.redhat.com/docs/manuals/csgfs/browse/rh-cs-en/> links from http://www.redhat.com/docs/manuals/csgfs/. (I think these are mirred on centos.org, but I

Hi all, Where i want to arrive: 1) having two storage server replicating partition with DRBD 2) exporting via GNBD from the primary server the drbd with GFS2 3) inporting the GNBD on some nodes and mount it with GFS2 Assuming no logical error are done in the last points logic this is the situation: Server 1: LogVol09, DRDB configured as /dev/drbd0 replicated to Server 2. DRBD seems to work

Hi all, I am trying to configure a failover multipath between 2 GNBD devices. I have a 4 nodes Redhat Cluster Suite (RCS) cluster. 3 of them are used for running services, 1 of them for central storage. In the future I am going to introduce another machine for central storage. The 2 storage machine are going to share/export the same disk. The idea is not to have a single point of failure

hello folks! here's my situation: i've got two WTI RPB+ remote power switches (essentially a 5-port power strip which you can control via serial interface to make each of the ports switch on and off independently). they work fine; i plug a DB-9 cable into the back of my machine, fire up minicom, and i have full control. however, my eventual plan is to use these as fencing

Hello all: I'm having a strange problem with GNBD and LVM on two fully updated CentOS 5.5 x86_64 systems. On node1, I have exported a gnbd volume. lvcreate -L 500M -n mirrortest_lv01 mirrorvg gnbd_serv gnbd_export -d /dev/mirrorvg/mirrortest_lv01 -e node1_lv01 On node2 I have imported the volume: gnbd_import -i node1 Next, on node2 I attempt to create a mirrored LV with the

Hi all, We're looking at deploying a small Xen cluster to run some of our smaller applications. I'm curious to get the lists opinions and advice on what's needed. The plan at the moment is to have two or three servers running as the Xen dom0 hosts and two servers running as storage servers. As we're trying to do this on a small scale, there is no means to hook the

Anyone have any experience with GNBD? What kind of performance and security differences are there in running GNBD vs NFS? We're planning an implementation with an external storage array (DAS) and want to use a shared filesystem. We have 10 or so clients that will be connecting to the shared filesystem. We have duplicate systems and arrays and were planning on using keepalived for

Hi? All: I have two physical machines as KVM hosts (clusterA.RHCS and clusterB.RHCS) , an iscsi target set into GFS. All I want is a HA Cluster which could migrate all the virtual machines on a node to another when the first node failed into some error status. So I created a cluster "cluster" using RHCS ,added the two hosts into the cluster . created a fence device . for every virtual
