Hi -

I'm working on setting up MySQL with DRBD/Pacemaker/Corosync on Ubuntu 12.04 LTS. The Internet appears to have some memory of there being Linode articles for 10.04 LTS that are now scrubbed from the library. I'm getting a couple errors:

First, it is looking for a kernel module when launching the cluster manager:

# service cman start
Starting cluster:
Checking if cluster has been disabled at boot... [ OK ]
Checking Network Manager... [ OK ]
Global setup... [ OK ]
Loading kernel modules... FATAL: Module configfs not found.
[FAILED]


I think this module comes from open-iscsi (It looks like this is something that Linode doesn't compile in?), but, here we go with apt-get install open-iscsi:

* Starting iSCSI initiator service iscsid [fail]
* Setting up iSCSI targets [ OK ]
invoke-rc.d: initscript open-iscsi, action "start" failed.
dpkg: error processing open-iscsi (--configure):
subprocess installed post-installation script returned error exit status 1
Errors were encountered while processing:
open-iscsi


and then I get a message in the syslog:

iscsid: Missing or Invalid version from /sys/module/scsi_transport_iscsi/version. Make sure a up to date scsi_transport_iscsi module is loaded and a up todate version of iscsid is running. Exiting...


Anybody have any luck making DRBD work with Linode? Rackspace has a number of tutorials saying how to do it with their Cloud Storage; I remember doing this previously with Linode on 10.04 LTS, but now, building a new cluster, it doesn't appear to work.

To get over that one, switch to the pv-grub kernel:

However, you'll find there are a couple things missing from the ubuntu 12.04 virtual kernel you have to add:

Also, if you got to where I did, and you switch kernels, purge the open-iscsi package as well.
