1. fetch sources

says to use
wget http://oss.linbit.com/drbd/8.4/drbd-latest.tar.gz
but you get a 404 and you really need

The usual way that DRBD works is that only one of your pair of servers has access to the data on the DRBD device at any one time. It is possible to run it in multiple-primary mode but it's mor... [by TrevorH]
I have an amazing dual-primary DRBD iSCSI SAN configured with aacraid, drbd and targetcli (iSCSI) to sit under VMware. Everything works great except for the order in which the services start.
DISCLAIMER: Adaptec 6805E cards in RAID1 were faster than mdadm RAID1.
So I am trying to set up a redundant NFS share in a cloud environment(all links internal, half gig links), and I am looking into using heartbeat for failover, but all the guides seem to be about combining DRBD and heartbeat to create a robust environment.
I am getting my hand to setup redhat cluster on Centos 6 using its python GUI interface LUCI.
As of now I am following Redhat documentation to set this up.
I was wondering if anyone knows how to setup Virtual machines on cluster with shared resources on two hosts. (Either as HA-LVM resource or GFS resource)
Currently I achieve this with DRBD.
I'm trying to set up two machines synchonizing with DRBD. The storage is setup as follows: PV -> LVM -> DRBD -> CLVM -> GFS2.
DRBD is set up in dual primary mode. The first server is set up and running fine in primary mode. The drives on the first server have data on them. I've set up the second server and I'm trying to bring up the DRBD resources.
Under load, DRBD crashes and it unmounts itself.
Is there anyway to optimize DRBD to prevent from happening again?
Is there anything to look out for?
I'm going to add drbd to an existing LVM, I want to keep LVM data.
