vmkfstools issue: Unable to clone using -i flag - DISKLIB-LIB_CLONE : Failed to clone : Data corruption detected (2567).

[krishnan601]

We are trying to migrate a vm from RHEL environment to VMware environment. The source file/image is qcow2 format.  The source disk/file is not having any filesystem corruption as evidenced by "fsck". The qemu-img conversion is used to convert it to an intermediary vmdk image. This intermediary image is converted/clone to a final bootable VMware vmdk image using the vmkfstools.

Command Used:

vmkfstools -v5 -i <servername>.tmp.vmdk -d thin <servername>.vmdk

Message displayed:

DISKLIB-LIB_CLONE   : Failed to clone : Data corruption detected (2567).

Failed to clone disk: Data corruption detected (2567).

Any help is appreciated.

The disk might have gone bad. Any challenges in using the VMware Converter?

We could power on the qcow2 image in the RHEL KVM environment.  What we are attempting is to shutdown the KVM guest, copy the qcow2 image and then convert it first using qemu-img and then using vmware's vmkfstool to make it as bootable image.  So far we did migrate a few of the qcow2 images to VMware environment but this is the first one that has an issue.  Is the VMware converter a free tool? If so where can it be downloaded from?

Yes, it is a free tool. Can be downloaded from the below link and a link to the user's guide. You will find many blogs on the net explaining the conversion process step-by-step -
