Hi All, I am new to DRBD and have what is likely a silly question, I hope this is the appropriate place to ask and apologize if it isn't. I have built a 2 node Proxmox cluster and am using LVM over DRBD, with DRBD in dual primary mode. It seems to be running flawlessly and I am very happy. I have been able to live migrate an asterisk box while in a conversation without even noticing, and now I am hooked. I wanted to experiment with High Availability and decided to build an NFS setup with heartbeat. I would like to do this with Virtual machines running on the Proxmox cluster. Through my experimentation I have found that I can mount the LVM volumes as a drive in KVM based VMs (1 NFS server one the master and the 2nd on a Node), and have heartbeat automatically fail them over. However, the two LVM volumes don't seem to sync up properly. If I copy a file to the volume on the master, stop heartbeat, the secondary will pickup the IP address, mount the volume, but the newly copied files won't be there, even if I wait a minute before performing the failover. I am wondering if what I am trying is even possible. As I said I am very new to this, and have been reading as much as I can. I am viewing the DRBD setup as a physical device, and thought that the writes would be automatically replicated. I am wondering if because I am writing to the logical volume from the VMs directly if the DRBD aspect is bypassed, or if there is something else I am missing (I am sure there is much I am missing). Thanks in advance.
