Setting up a HA iSCSI / NFS target using this document, http://www.linbit.com/fileadmin/tech-guides/ha-iscsi.pdf, and I am unable to find a way to use the puppetlabs-corosync module to emulate this command crm(live)configure# primitive p_drbd_coraid23 ocf:linbit:drbd \ params drbd_resource=coraid23 \ op monitor interval=29 role=Master \ op monitor interval=31 role=Slave crm(live)configure#

All, There are drbd82 RPMS for CentOS-4 and CentOS-5 (i386 and x86_64) for testing here: http://people.centos.org/~hughesjr/drbd/ These are designed to be able to live in the same repository as the current STABLE versions. These RPMS are designed as CONFLICTS and not upgrades as there may be some manual actions to upgrade, especially on CentOS-4. Here is an article on the upgrade process:

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

I try not to post my real name on the internet. I'm basically asking for commit access for user sub page space for formatting, & staging of documents for management review. When I'm actually @ linbit ill probably start the motions to have an official account something like "linbit-usa" to publish the works under. I'm used to mediawiki, moinmoin wiki is new to me.

Hi list, I had to relocate my third node in a classic DRBD 8.4 three node set up to a new host.  I am having difficulty making the stacked resource the primary.  I am following this guide: https://www.linbit.com/drbd-user-guide/users-guide-drbd-8-4/#s-three-nodes Specifically this: > > > 5.18.3.

Hi, I want to combine all the above mentioned technologies. The Linbit pages warn not to use the drbd: VBD with HVM DomUs. This page however: http://publications.jbfavre.org/virtualisation/cluster-xen-corosync-pacemaker-drbd-ocfs2.en (thank you Jean), simply puts two DRBD devices in dual primary mode and starts Xen DomUs while pointing to the DRBD devices with phy: in the DomU config files.

I've run into a problem mounting an OCFS2 filesystem on a DRBD device. I think it's the same one discussed at http://lists.linbit.com/pipermail/drbd-user/2007-April/006681.html When I try to mount the filesystem I get a ocfs2_hb_ctl: I/O error: [root at node-6A ~]# mount -t ocfs2 /dev/drbd2 /cshare ocfs2_hb_ctl: I/O error on channel while starting heartbeat mount.ocfs2: Error when

Ralph Angenendt, Fabian Arrotin, Akemi Yagi and I have been working on new DRBD packages for CentOS Extras. We have some packages that have been tested in the testing repository. LinBit has discontinued their 8.2 tree, so drbd83 will replace drbd82 in both CentOS 4 and CentOS 5 extras. DRBD 0.7.25 will remain in CentOS 4, however it gets no upstream support and I would recommend you upgrade to

I have an existing in-production LAMP server running Centos 5.1. It uses physical partitions on top of hardware RAID1, having / /home /var and /boot on separate partitions. We have a near-identical system I am thinking of bringing in as a DRBD/Heartbeat companion. One solution may be to use csync2 [http://oss.linbit.com/csync2/] on /etc and /usr/local (the only areas that will differ from

Hi all, I don''t know if my question doesn''t related to xen at all, how ever I am trying to use DRBD as my disk replication when I ran Remus. However when I run remus sometimes my Dom-U will be freezing. I see the log file and it seem caused by drbd frozen : 875.616068] block drbd1: Local backing block device frozen? [ 887.648072] block drbd1: Local backing block device

I'd recomend drbd over a nbd + raid solution: * drbd knows to read from local device only so

Regardless of the filesystem (i''ve used reiserfs, xfs, ext3), whenever I mount a fresh DRBD partition I get some nasty kernel messages. This is under Debian Sarge, Xen kernel 2.6.11.12-xen0 (dom0) using DRBD v0.7.11 (pulled from Debian "testing"). This is what I did to create the partition. On both nodes I created a new LVM storage device and started DRBD: # lvcreate

Dear All, Currently using RHEL6 Linux and Kernel Version is 2.6.32-71.el6.i686 and DRBD Version is 8.3.10 DRBD is build from source and Configured DRBD with 2 Node testing with Simplex Setup Server 1 : 192.168.13.131 IP Address and hostname is primary Server 2 : 192.168.13.132 IP Address and hostname is secondary Finally found that drbd0, drbd1 mount failed problem *Found some error messages

Hello list, Working on migrating my existing High-Availability setups from CentOS 5.3 to 6.0, both x86_64. I generally setup a fairly simple 2 node active/passive cluster using DRBD , Heartbeat, and Pacemaker. Use these clusters to run our proprietary Medical software plus a few key services ( openvpn , Digi PortServer Daemon, etc.). I had a procedure in place for doing all of this under 5.3

Just some notes: For master <-> master setup (bi-directional sync) you need AFAIK a cluster filesystem. I have no idea how far this is supported w/ samab (ACLs, ...) Maybe a old tool related to drbd might be worth some testing too: http://oss.linbit.com/csync2/ Klaus ________________________________________ Von: samba-bounces at lists.samba.org [samba-bounces at

posting messages at 3am on a bright white page can give me auras, migraines, & seizures. A pc screen is much brighter than a piece of paper. "http://www.linux-ha.org/wiki/Main_Page looks pretty dead to me. has nothing to do with centos." Yes it does, I am saying I can't evade cents bureaucracy.
