Removing local-zfs (rpool)

[promoxer]

1. I have 2 pools, rpool and vpool
2. rpool was created by default during installation, however all my VMs reside on vpool and local-zfs is empty
3. Can I remove local-zfs and merge the freed space into local?

Yes but there is no point doing that. "local" and "local-zfs" share the full space. So with 0% data stored on "local-zfs" you got 100% space on "local" and vice versa. Those are both thin provisioned and not using fixed allocations.

Why do I have 40GB only in local-zfs and 110 GB in local? My storage total is 256 GB

Please show the output of zfs list -o space and zpool list -v.
