Hi guys I'm wondering if anyone here is using the GlusterFS OCF resource agents with Pacemaker on CentOS 7? yum install centos-release-gluster yum install glusterfs-server glusterfs-resource-agents The reason I ask is that there seem to be a few problems with them on 3.10, but these problems are so severe that I'm struggling to believe I'm not just doing something wrong. I created

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi! I think I stumbled on at least two bugs in the CentOS 7.2 pacemaker package, though I'm not quite sure if or where to report it. I'm using the following package to set up a 2-node active/passive cluster: [root at clnode1 ~]# rpm -q pacemaker pacemaker-1.1.13-10.el7_2.4.x86_64 The installation is up-to-date on both nodes as of the

Hi everyone, I need some help to setup my configuration failover system. My goal is to have a redundance system using Xen + DRBD + Corosync + Pacemaker On Xen I will have one virtual machine. When this computer has network down, I will do a Live migration to the second computer. The first configuration I will need is a crossover cable, won''t I? It is really necessary? Ok, I did it. eth0

Hi, I've just created again the gluster with NFS ganesha. Glusterfs version 3.8 When I run the command gluster nfs-ganesha enable - it returns a success. However, looking at the pcs status, I see this: [root at tlxdmz-nfs1 ~]# pcs status Cluster name: ganesha-nfs Stack: corosync Current DC: tlxdmz-nfs2 (version 1.1.16-12.el7_4.5-94ff4df) - partition with quorum Last updated: Wed Dec 20

Hi, We''re setting up fairly large Lustre 2.1.2 filesystems, each with 18 nodes and 159 resources all in one Corosync/Pacemaker cluster as suggested by our vendor. We''re getting mixed messages on how large of a Corosync/Pacemaker cluster will work well between our vendor an others. 1. Are there Lustre Corosync/Pacemaker clusters out there of this size or larger? 2.

Hi, In your ganesha-ha.conf do you have your virtual ip adresses set something like this?: VIP_tlxdmz-nfs1="192.168.22.33" VIP_tlxdmz-nfs2="192.168.22.34" Renaud De?: gluster-users-bounces at gluster.org [mailto:gluster-users-bounces at gluster.org] De la part de Hetz Ben Hamo Envoy??: 20 d?cembre 2017 04:35 ??: gluster-users at gluster.org Objet?: [Gluster-users]

Hello all, I am trying to create a corosync/pacemaker cluster using CentOS 6.0. However, I'm having a great deal of difficulty doing so. Corosync has a valid configuration file and an authkey has been generated. When I run /etc/init.d/corosync I see that only corosync is started. >From experience working with corosync/pacemaker before, I know that this is not enough to have a functioning

I checked, and I have it like this: # Name of the HA cluster created. # must be unique within the subnet HA_NAME="ganesha-nfs" # # The gluster server from which to mount the shared data volume. HA_VOL_SERVER="tlxdmz-nfs1" # # N.B. you may use short names or long names; you may not use IP addrs. # Once you select one, stay with it as it will be mildly unpleasant to # clean up

Hi all, We are currently running a NFS-based server centric setup. I would like to set up something where I can easily have more than one redundant server, security/authentication (this part seems a little flaky with NFS, at least did several years ago), with the capability to easily add/remove servers as necessary, take redundant servers down for maintenance, etc. Total volume we expect to run

Hi, I am trying to build a rock solid XEN High availability cluster. The platform is SLES 11 SP1 running on 2 HP DL585 both connected through HBA fiber channel to the SAN (HP EVA). XEN is running smoothly and I''m even amazed with the live migration performances (this is the first time I have the chance to try it in such a nice environment). XEN apart the SLES heartbeat cluster is

I am running a two-node web cluster on OCFS2 via DRBD Primary/Primary (v8.3.8) and Pacemaker. Everything seems to be working great, except during testing of hard-boot scenarios. Whenever I hard-boot one of the nodes, the other node is successfully fenced and marked ?Outdated? * <resource minor="0" cs="WFConnection" ro1="Primary" ro2="Unknown"

Hello, We are having a problem with a 3-node cluster based on Pacemaker/Corosync with 2 primary DRBD+OCFS2 nodes and a quorum node. Nodes run on Debian Squeeze, all packages are from the stable branch except for Corosync (which is from backports for udpu functionality). Each node has a single network card. When the network is up, everything works without any problems, graceful shutdown of

Hello, this is my scenario: 1)I've created a Pacemaker cluster with the following ocfs package on opensuse 11.3 64bit ocfs2console-1.8.0-2.1.x86_64 ocfs2-tools-o2cb-1.8.0-2.1.x86_64 ocfs2-tools-1.8.0-2.1.x86_64 2)I've configured the cluster as usual : <resources> <clone id="dlm-clone"> <meta_attributes id="dlm-clone-meta_attributes">

Hi to all, this is My first time on this mailinglist. I have a problem with Ocfs2 on Debian etch 4.0 I'd like when a node go down or freeze without unmount the ocfs2 partition the heartbeat not fence the server that work well ( kernel panic ). I'd like disable or heartbeat or fencing. So we can work also with only 1 node. Thanks

Hello, I have two OCFS file file systems mounted at /ocfs_1 and /ocfs_2. I have unmounted both OCFS file systems and was trying to then offline and unload OCFS.

Hi all. I am currently working for a hosting provider in a 100+ linux hosts' environment. We have www, mail HA solutions, as storage we mainly use NFS at the moment. We are also using DRBD, Heartbeat, Corosync. I am now gathering info to make a cluster with: - two virtualization nodes (active master and passive slave); - two storage nodes (for vm files) used by mentioned virtualization nodes

Hi, We have a two node cluster running SLES 9 SP2 connecting directly to an EMC CX300 for storage. We are using OCFS(OCFS2 DLM 0.99.15-SLES) for the voting disk etc, and ASM for data files. The system has been running until last Friday when the whole cluster went down with the following error messages in the /var/log/messages files : rac1: Jul 7 14:56:23 rac1 kernel:

I'm trying to setup a pair of FreePBX-4.211.64 boxes using Pacemaker, Corosync, and DRBD. All the examples I've found so far use Heartbeat, but Heartbeat is not in the repositories and doesn't want to compile from source. Does anyone have a working configuration they can share or a tutorial they can point me to? Also, what does drbdlinks bring to the party? Isn't just linking
