The Initiators I use are: VMWare ESX 3.0.x, VMWare ESX 3.5.x, Micrsoft<br>
iSCSI Initiator 2.08, and Linux (RHEL 5, SUSE 10).<br>

I gave SQLIO a run with your params and I'm not getting the concurrent<br>
write issue.</blockquote><div><br>The bizarreness continues; downgrading DRBD is of no help either :( Although, it is encouraging in a way suggesting that this might be finally isolated. I assume you're checking the logs of the primary node?<br>

The hardware I run DRBD is a pair of HP Proliant DL380 G4 servers with<br>
12GB of RAM and P600 SAS controllers. The machines are currently<br>
replicating 1.8TB of data. I run DRBD under SuSE 10SP2 and use IET<br>
stock from SuSE but the DRBD is 8.0.16.</blockquote><div><br> What is the kernel version on the target? Version of Windows on the initiator? Could you share the relevant portions of ietd.conf and drbd.conf?<br><br>Thanks,<br>
