Shares
File sharing is one of the primary benefits of a NAS. TrueNAS helps foster collaboration between users through network shares.
TrueNAS allows users to create and configure Windows SMB shares, Unix (NFS) shares, and block (iSCSI) shares targets.
When creating zvols for shares, avoid giving them names with capital letters or spaces since they can cause problems and failures with iSCSI and NFS shares.
TrueNAS Enterprise
iXsystems TrueNAS Enterprise customers should contact TrueNAS Enterprise Support to receive additional guidance on system configuration.
AFP Migration
Since the Apple Filing Protocol (AFP) for shares is deprecated and no longer receives updates, it is not present in TrueNAS.
Adding a Basic Time Machine SMB Share
To prevent unexpected failures in SMB shares, TrueNAS 25.04 and later automatically disables SMB2/3 lease support and AAPL extensions (typically used to configure Time Machine) globally when multiprotocol SMB/NFS shares are enabled.
Adding iSCSI Block Shares
TrueNAS has implemented administrator roles to align with FIPS-compliant encryption and security hardening standards. The Sharing Admin role allows the user to create new shares and datasets, modify the dataset ACL permissions, and start/restart the sharing service, but does not permit the user to modify users or grant the sharing administrator role to new or existing users.
Adding NFS Shares
Creating a Network File System (NFS) share on TrueNAS makes a lot of data available for anyone with share access. Depending on the share configuration, you can restrict users to read or write privileges.
NFS Shares Screens
If you have not added NFS shares to the system, the NFS widget shows text stating general information about the Unix (NFS) shares until a share is added.
Block (iSCSI) Share Target Screens
If you have not added iSCSI shares to the system, the iSCSI widget shows text stating general information about the block (iSCSI) share targets until a share is added.
Multiprotocol Shares
To prevent unexpected failures in SMB shares, TrueNAS 25.04 and later automatically disables SMB2/3 lease support and AAPL extensions (typically used to configure Time Machine) globally when multiprotocol SMB/NFS shares are enabled.
Setting Up Fibre Channel
The Fibre Channel feature is available to Enterprise-licensed High Availability (HA) and non-HA systems. Any Enterprise system, equipped with the required fibre channel hardware can implement this feature.
This article provides instructions for VMware VCenter ESXi. If you are using a different platform for your block share backups, use the documentation for that platform for alternative instructions for the ESXi process documented in this tutorial. .
When setting up iSCSI fibre channel for the first time:
