Resizing the Replicated VM Disk - Caution!!!!!

  • On the recovery site, rename the folder in which the virtual machine is replicated to. This prevents the replicated data from removing when removing replication from the virtual machine.
  • Disable replication of the virtual machine you want to resize.
  • At the protected site, increase the size of the desired virtual machine disk file.
  • At the recovery site, log in to an ESXi host that can access the datastore in which the virtual machine is replicated to.
  • Run this command to change the directory to the datastore and folder in which the replicated disk is stored:
           cd /vmfs/volumes/virtual_machine_datastore/virtual_machine_folder/
  • Run this command to increase the size of the replicated vmdk using vmkfstools:
          vmkfstools –X 50G virtual_machine.vmdk
          Note: The preceding command increases the size of a virtual disk to 50 GB.
  • At the recovery site, restore the virtual machine folder to the original name.
  • Reconfigure the replication for the virtual machine. Ensure to select the Specify datastore folder option to select the folder in which the replicated disk is stored.You can see a prompt that shows:
         A file with the name ‘[<datastore>] <folder>/<filename> already exists. Press Yes to use file as an initial copy.
        Select Yes to use the already replicated disk as a seed. If you are using the Web Client, you must browse for the correct folder.
