VMware ESXi

If you have issues starting up the Virtual Machine in your VMware ESXi 5.1 infrastructure: You might need to do the following.

  • Open a console to ESXi host. 
  • Run this command to load the multiextend module
#vmkload_mod multiextent
  • Convert the vmdk image, by going to the location of the virtual machine and then run the following command
#vmkfstools -i ./TonidoCloud-disk1.vmdk ./newdiskimage.vmdk -d zeroedthick 
  • Delete the original disk 
#vmkfstools -U ./TonidoCloud-disk1.vmdk
  • Rename the cloned disk to the original disk name
#vmkfstools -E ./newdiskimage.vmdk ./TonidoCloud-disk1.vmdk
  • Unload the multiextent module
#vmkload_mod -u multiextent
