On Sat, Apr 7, 2012 at 2
I need to test that DRBD will peacefully cohabit with Oracle VM. I want to
build a single-node DRBD array and need my resource in WFConnection
Primary/unknown Uptodate/DUnknown.
Otherwise I need two drbds (I can do that, but it's not germane to this
test).
I did a create-md (successful) and a drb

I'm looking at a Primary/Secondary, Protocol B (or maybe A with Proxy) for a

Anyone got any experience with OVM 3 and DRBD?

suming you have
VMa, VMb and VMc on Disk1, and VMd, VMe and VMf on Disk2, you could.
Build a drbd array on New space.
Migrate VMa, VMb and VMc to it.
Build a drbd array on the space of Disk1.
Migrate VMd, VMe and VMf to it.
Recover the space of Disk2.

Mark said: "Snapshot creation requires that VMware tools are installed".
This is not correct (at least on ESXi4 and 5).
"quiesce VM" requires VMware tools, VDR may require VMware tools, but
snapshots do not.
This doesn't affect the OP's problem, but the incorrect statement needed
illumination.

I'd say the error is in the STONITH method. You evidently are giving the UPS a
"SHUTDOWN" command when you should be giving it a "SLEEP" or "SUSPEND" command

Is the new filesystem for VMWare's vSphere 5 cluster aware? I continue to
see references to GFS2 and OCFS2 but never a mention of VMFS5. I'm just
curious for now, because I'm running single primary. If I could save the
network latency for reads from one host that would be sweet!

And on 8.4.0 up, you can use the same IP and port. See volumes:

I sure hope that 0.8.4 is a typo. We are up to version 8.4.0. If you are really
running drbd from years ago, I'd suggest an upgrade. Sorry, but I don't have
any input on your throughput issue.

I'm in the middle of a "verify the upgrade procedure" for drbd 8.3.10 to
8.4.0.
Just for chucks, I did the dd command here, to see the performance I get.

verify and disconnect/connect (of the secondary node) will get you synced up
