similar to: cluster.conf validating, but cman not starting

Hi Guys, I'm using centos 6.5 as guest on RHEV and rhcs for cluster web environment. The environtment : web1.example.com web2.example.com When cluster being quorum, the web1 reboots by web2. When web2 is going up, web2 reboots by web1. Does anybody know how to solving this "fence loop" ? master_wins="1" is not working properly, qdisk also. Below the cluster.conf, I

Hi. Today I have updated my cluster installation with the version cman-2.0.115-1 through yum update. When I have started the cman service , it fails. If I execute cman_tool debug I get the following error : [CMAN ] CMAN 2.0.115 (built Sep 16 2009 12:28:10) started aisexec: symbol lookup error: /usr/libexec/lcrso/service_cman.lcrso: undefined symbol:

Hi everybody, I have tested CTDB+GFS2+CMAN under Debian. It works good but I do not understand some points. It is possible to run the CTDB defining it under services section in cluster.conf but running it on the second node shuts down the process at the first one. My CTDB configuration implies 2 active-active nodes. Does CTDB care if the node starts with clean_start="0" or

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

hello, i opened a bug on the ocfs2 bugzilla reporting difficulty i have utilize a different cluster stack than o2cb. link: http://oss.oracle.com/bugzilla/show_bug.cgi?id=1325 to summarize i'd like to use ocfs2 on an ubuntu server with drbd and ctdb. ctdb requires fcntl locks for its lock files. however o2cb doesn't provide that functionality whereas cman (redhat's cluster manager

I currently have a few CentOS 5.2 based Xen clusters at different sites. These are built around a group of 3 or more Xen nodes (blades) and some sort of shared storage (FC or iSCSI) carved up by LVM and allocated to the domUs. I am "managing" the shared storage (from the dom0 perspective) using cman+clvmd, so that changes to the LVs (rename/resize/create/delete/etc) are

Hello, I'm planning migration of current two clusters based on CentOS 6.x with Cman/Rgmanager going to CentOS 7.x and Corosync/Pacemaker. As the clusters and their services are on the same subnet, and there no particular security concerns differentiating them, I'm also evaluating the option to transform the two clusters into a unique 4-node one during the upgrade. Currently I'm

Hi, I need to create a real-time replication of a partition between two servers with centos 6.4, I am researching and finding difficulty with drbd, corosync, someone indicate material, do not need to run script automatically if a node drops only replicate. Grateful. -- Sergio.Alex

hi guys, we're evaluating the available clustering options to get ctdb up and running for a highly available file server. we've set up both gluster and ocfs2 both on seperate 2 node setups. ocfs2 seems to provide better throughput and iops to samba clients than does gluster and that is comparing a single node server to a ctdb clustered 2 node server. problem with ocfs2 is that i've

Hello, Several machine cannot joint the cluster after a reboot.

Hi, I have two KVM hosts (CentOS 7) and would like them to operate as High Availability servers, automatically migrating guests when one of the hosts goes down. My question is: Is this even possible? All the documentation for HA that I've found appears to not do this. Am I missing something? My configuration so fare includes: * SAN Storage Volumes for raw device mappings for guest vms

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 have an 14.04 server with Asterisk 13.5 that will recognize it. It has corosync and corosync-dev version 2.3.3 on it. The one I can?t get to recognize it is 16.04 ubuntu, with corosync and -dev version 2.3.5. Won?t be recognized by ./configure for Asterisk 13.17, 13.16, or Asterisk Certified 13.13. I REALLY need some help figuring this out. ? Thanks! From: asterisk-users-bounces at
