RDM filesystem inconsistencies caused by automatic disk defragmentation (1007081)


  • Your environment has a corrupted filesystem
  • You encounter unreadable disk files
  • Your environment has corrupted partition tables
  • You cannot boot a virtual machine


Automatic disk defragmentation is a 3rd party feature that has the ability to defragment unmounted NTFS volumes that are presented to the VMware Consolidated Backup proxy. This means that it can defragment RDM LUNs. Unfortunately, this creates the possibility of inconsistencies in the file system if there is a virtual machine running on that RDM.
The Automatic Defragment option causes the defragmentation to take place.
Consult your vendor documentation to obtain instructions for disabling this feature in the version of the product that is installed on the VCB Proxy server.
