Why can’t I create a mirror?


  • The common cause of this problem is that the volume on either source or target is in use by another process. Stop the process that is accessing the volume and try again. The SIOS DataKeeper software requires exclusive access to the target volume during the creation of the mirror.
  • The target volume must be as large, or larger, than the source volume. It is recommended that the user compare the target volume size with the source volume size using the Disk Management utility. If the sizes are not the same, recreate the target partition a little larger. See Volume Considerations for more information.
  • An error experienced during Create Mirror could indicate that the target volume is corrupt. If this occurs, format the target volume and attempt to create the mirror again.
