Recently I was trying to do P2V of a Windows 2003 STD Server to ESX platform. P2V was failed with error “Failed to clone Volume” and log files had the below message. Block level cloning of the disk was failing.

ERROR -- Convert: converter.fault.CloneFault
(converter.fault.CloneFault) {
   dynamicType = <unset>,
   faultCause = (vmodl.MethodFault) null,
   description = "BlockLevelVolumeCloneMgr::CloneVolume: Detected a write error during the cloning of volume \WindowsBitmapDriverVolumeId=[9F-14-A0-14-00-7E-00-00-00-00-00-00]. Error: 4641 (type: 1, code: 290)",
   msg = "",
}

Did some troubleshooting on the disk level, but didn’t help.

Finally got it solved by Changing(Hardcode) the NIC Speed to 100 MBpS from Auto on the Physical system.

      Hi Ben, Hope this helped you.

    I’m having the same problem, and tried your suggestion without any luck – however, i wanted to clarify that I am understanding you correctly. When you say you changed (hard coded) the NIC speed to 100MBps on the physical system, do you mean on the physical NIC of the machine that is being converted, the server, or the machine that is handling the conversion? also, can you confirm if your machines are on a 100MBps network or a 1GBps network? in my scenario, my network is 1GBps, but I have the physical machine that is being cloned on a 100MBps switch – so the ESXi server AND the machine running the standalone converter are connected to each other @ 1GBps, but the machine that is being converted is connected to both @ 100MBps because it is behind that switch. I also have two options on the NIC – 100MBps Full Duplex or Half Duplex. I picked Full Duplex, and retried the conversion – but it still failed with the exact same error message you described above.

    any suggestions would be greatly appreciated!
    thanks!

      Welcome!

      Could you check hardcoding the switch port also to 100MBps Full duplex?

      Thanks

    This worked for me too… Thanks.

    I did the opposite and changed my physical nic card from 100 to auto, which bumped up the speed from 100mb to 1gig.

    I know this is a couple years old but want to say thanks. I had same problem and changed from Auto to 100/Full and My image is up to 10% now. Always failed while still on 1%. So I think I’m good. Thanks.

      🙂 Thats great, Base architecture haven’t changed 😉

      Cheers!

    Didnt work for me im afraid… just took longer to get to 14% before failing 🙂
    Thanks anyway…
