Description
You have one common NFS datastore for storing images.
You have few clusters with different system datastores with different types: example fs_lvm and shared
You want to use this images datastore for deploying VMs to both systems.
For images datastore you can set:

  • TM_MAD=fs_lvm -then it will work with fs_lvm but will not work with shared system ds (return errors like device not found)
  • TM_MAD=shared -then it will work with shared but will work wrong with fs_lvm system ds (it will create files instead devices)

To Reproduce

  • Create fs_lvm and shared systemds.
  • Create shared another one for images.
  • Try to apply mentioned options for it.

Expected behavior
Driver will take decision based on TM_MAD parameter of system datastore (not images)
like for shared system datastore it will operate files, and for fs_lvm datastore it will operate lvm partitions
