Thats correct. The problem was with my perception of how it suppose to work versus the actual behavior. Truck based replication worked perfectly for me. After initial UpToDate/UpToDate message I untared the my directory structure on drbd mounted device and monitored dw (disk write) status from which I was able to see disk writes happening. Before this I was hoping to see UpToDate/Inconsistent(or Outdated) ds message, but that was just my perception.<br><br>Thanks a lot for help.<br><br>Regards,<br>Jay<br><br><br>> Date: Sat, 31 Oct 2009 10:17:22 +0100<br>> From: lars.ellenberg@linbit.com<br>> To: drbd-user@lists.linbit.com<br>> Subject: Re: [DRBD-user] Truck replication<br>> <br>> On Thu, Oct 29, 2009 at 07:41:16PM +0000, jay b wrote:<br>> > <br>> > Hi All:<br>> > <br>> > I am stuck with truck based replication.
