<DIV>If you setup matching sized partitions on .39, then it should be fairly </DIV>
<DIV>simple. Update .37's resource configuration to point to .39 instead of </DIV>
<DIV>.38. Then copy /etc/drbd* from .37 over to .39, Use 'drbdadm create-md </DIV>
<DIV><res>' to setup the new DRBD resource backing device. Make sure that the </DIV>
<DIV>resources on .37 are in WFConnection state ('drbdadm attach <res>' if </DIV>
<DIV>they aren't) and then, on .39, run 'drbdadm connect <res>'.</DIV>
<DIV> </DIV>
<DIV>If it works well, you should be able to watch /proc/drbd and see that it </DIV>
<DIV>is sync'ing from .37 (.37 should show each resource in the connection </DIV>
<DIV>state "SyncSource" and the resource(s) on .39 should be in </DIV>
<DIV>"SyncTarget"). Once the sync completes, you data is safe again.</DIV>
<DIV> </DIV>
<DIV>If you have any specific trouble, share the details of your </DIV>
<DIV>configuration (distro/drbd/cluster stack details and versions). Config </DIV>
<DIV>files also help us understand your setup and thus offer better advice.</DIV>
<DIV> </DIV>
<DIV>good luck!</DIV>
<DIV> </DIV>
<DIV>PS - If you're concerned about the process, create a few VMs and </DIV>
<DIV>replicate the current state (create two VMs, set them us as you had </DIV>
<DIV>before, delete one of the VMs, create a new VM and walk through the </DIV>
<DIV>process of adding it to the previous VM). It's _always_ better to test </DIV>
<DIV>before trying anything on production systems.</DIV>
