Re: [DRBD-user] DRBD Not Starting on Boot / Pacemaker Errors

As an update, I managed to get DRBD starting up on boot by using update-rc.d. It is currently starting with the default priority (20), which is lower than corosync's, ocfs2's, etc. My presumption is that this means that DRBD should be starting before those services. Nevertheless, I continue t

[DRBD-user] DRBD Not Starting on Boot / Pacemaker Errors

Hello folks, I'm noticing that DRBD is not starting automatically on boot in my Ubuntu 8.04 LTS Server implementation. All was working fine with DRBD and Pacemaker / Corosync until I restarted the two nodes. DRBD did not startup on boot, and crm_mon is showing errors. I was wondering how (1)

Re: [DRBD-user] drbd nodes can not see each other

Hello, First thing to check out is your firewall / iptables. Put your firewall down on both nodes with 'service iptables stop' and then do 'service drbd restart' on both nodes. If that works, then your problem is that you have not mutually opened the ports defined for each drbd resource in t

[DRBD-user] DRBD and Pacemaker configuration

I have a simple DRBD mount with two nodes that the CRM promotes to Master on fail. My problem occurs when I sleep one node and then wake the failing node back up. In this instance I end up with two Primary (Split Brain) nodes but it is my understanding that Pacemaker tries to promote and use the

[DRBD-user] drbd support added to opensvc clustering tool

Hi list, this note to let you know we added the drbd support to OpenSVC clustering tool. drbd devices are treated as disk resources by OpenSVC : they implement the start, stop and startstandby commands. o Start sets up the disk attachment, the connection and promote role to primary. o Stop uncon

DRBD is not creating the /dev/drbd0 device. Everything else seems to be happy. I went through the usual steps setting everything up and there were no apparent errors.

[DRBD-user] Resource host by name instead of address

Hi, I am new to DRBD, just tried to setup my first sample cluster and stumbled over the first problem. I'd like to specify the hosts my resources reside on by hostnames rather than by IP addresses. The reason is that I want to setup a small cluster over a wide-area network (WAN) and the hosts invo
