BlockLevelVolumeCloneMgr::CloneVolume: Detected a write error during the cloning of volume Disk#0_Partition#1. Error: 37409 (type: 1, code: 2338)",

Hi all,

     I have tried to convert a power on physical machine to a workstation vm and it always failed at 3%-5%. The converter showed the same error message "BlockLevelVolumeCloneMgr::CloneVolume: Detected a write error during the cloning of volume Disk#0_Partition#1." every time. I have made a disk check using HD Tune which showed no bad blocks.

     Source OS: windows server 2008

     Converter version: 6.0.0 build-2716716

     ESXi: 6.0

     Do I need to try a file level clone?  Would be grateful if anyone can give me some advice.

From logs I see you trying to convert a physical machine to ESX 6 (not to workstation format).

The error is:

As a possible solution you can try to disable SSL communication with ESX and try again.

Change the value of the tag <nfc><useSsl> to false in converter-worker.xml then restart the worker service.

HTH

The real solution is to get logs from the ESX and investigate why SSL connection fails, probably there are difference between supported SSL/TLS versions from both sides.

I suggest you try performing file level cloning and check if the issue persists. however disabling SSL while conversion has its performance benefits.
