AFP Migration
2 minute read.
When creating a share, do not attempt to set up the root or pool-level dataset for the share. Instead, create a new dataset under the pool-level dataset for the share. Setting up a share using the root dataset leads to storage configuration issues.
Since the Apple Filing Protocol (AFP) for shares is deprecated and no longer receives updates, it is not present in TrueNAS.
However, users can sidegrade AFP configurations into TrueNAS 24.04 to migrate previously-saved AFP configurations into SMB configurations.
To prevent data corruption that could result from the sidegrade operation, in TrueNAS, go to Windows (SMB) Shares, select the for the share, then select Edit to open the Edit SMB screen. Click Advanced Options and scroll down to the Other Options section. Select Legacy AFP Compatibility to enable compatibility for AFP shares migrated to SMB shares. Do not select this option if you want a pure SMB share with no AFP relation.
Netatalk service is not present in TrueNAS 21.06 or later. AFP shares automatically migrate to SMB shares with the Legacy AFP Compatibility option enabled. Do not clear the Legacy AFP Compatibility checkbox, as it impacts how data is written to and read from shares. Any other shares created to access these paths after the migration must also have Legacy AFP Compatibility selected.
Once you have migrated to TrueNAS 24.04, you can find your migrated AFP configuration in Shares > Windows Shares (SMB) with the prefix AFP_. To make the migrated AFP share accessible, start the SMB service.
Since AFP shares migrate to SMB, you must use SMB syntax to mount them.
On your Apple system, press +K or go to Go > Connect to Server….
Enter smb://ipaddress/mnt/pool/dataset, where:
- ipaddress* is your TrueNAS IP address
- pool is the name of the pool
- dataset is the name of the shared dataset
