I recall a similar question where we had to set up a filesystem, but I can't remember if we used `vim` for editing fstab or if there was another editor we preferred.

I think the `vdo create` command is crucial here, but I might mix up the parameters. Did we use `--device` and `--vdoLogicalSize` in the same way?
