Description
Currently fallocate -d command is executed on every new image allocated in a fs datastore. The goal of this is to sparse the resulting files to save disk space and reduce copying times.

Two different behaviors have been found when the underlying filesystem doesn't support the fallocate call:

  • The command fails (this case is already controlled by the driver).
  • The command hung indefinitely.

As the advantages of calling fallocate usually don't apply to the file system which doesn't support the fallocate call it will be nice to allow disabling this call when necessary.
