What is the difference between a dataset and ZVOL?

zvol– These are a bit different that a dataset. If you were to think of a dataset as a NAS-type device (i.e. file-based), then the zvol is more of a SAN-type device (block base). If you want to carve out a chunk of storage and present it over iSCSI, you would use a zvol.

What is the FreeNAS system dataset?

The system dataset stores debugging core files and Samba4 metadata such as the user/group cache and share level permissions. If the FreeNAS® system is configured to be a Domain Controller, all of the domain controller state is stored there as well, including domain controller users and groups.

What is a FreeNAS Vdev?

A vdev can be a single disk, a stripe, a mirror, a RAIDZ1, RAIDZ2, or a RAIDZ3. After a vdev is created, more drives cannot be added to that vdev. However, a new vdev can be striped with another of the same type of existing vdev to increase the overall size of the pool.

How do I change my TrueNAS ACL?
