# Upgrading from Netatalk 2

## Overview

There are two major changes in Netatalk:

1. New configuration file `afp.conf`, obsoleting all previous configuration files

2. New AppleDouble backend "`appledouble = ea`" which stores Mac metadata and resource forks in extended attributes of the filesystem

### New configuration

- ini style syntax (like Samba’s smb.conf)

- one to rule them all: configure AFP settings and volumes in one file

- obsoletes `afpd.conf`, `netatalk.conf`, `AppleVolumes.default` and `afp_ldap.conf`

most option names have changed, read the full manpage afp.conf for details

### New AppleDouble backend

New AppleDouble backend "`appledouble = ea`" which stores Mac metadata and resource forks in extended attributes of the filesystem.

- default backend (!)

- requires a filesystem with Extended Attributes, fallback is "`appledouble = v2`"

- converts filesystems from "`appledouble = v2`" to "`appledouble = ea`" on the fly when accessed (can be disabled)

- `dbd` can be used to do conversion in one shot

Implementation details:

- stores Mac Metadata (eg FinderInfo, AFP Flags, Comment, CNID) in an Extended Attributed named “`org.netatalk.Metadata`”

- stores Mac ResourceFork either in

  - an Extended Attribute named “`org.netatalk.ResourceFork`” on Solaris w. ZFS, or in

  - an extra AppleDouble file named “`._file`” for a file named “`file`”

- the format of the ._ file is exactly as the Mac’s CIFS client expects it when accessing the same filesystem via a CIFS server (Samba), thus you can have parallel access from Macs to the same dataset via AFP and CIFS without the risk of loosing data (resources or metadata). Accessing the same dataset with CIFS from Windows clients will still break the coupling of “`file`” and “`._file`” on non ZFS filesystems (see above), so for this we still need an enhanced Samba VFS module (in the works).

As these days the only applications making use of Resource Forks are Adobe Photoshop (image preview) and Postscript Type 1 fonts, even on e.g. Linux you’ll get rid of 99% of any extra Netatalk AppleDouble files (and folders).

### Other major changes

- New service controller daemon netatalk which is responsible for starting and restarting the AFP and CNID daemons. All bundled start scripts have been updated, make sure to update yours!

- The CNID databases are now stored under `/var/netatalk/CNID/` by default. You can use `configure --localstatedir=PATH` at compile time to change the location.

- Netatalk 2.x volume options “usedots” and “upriv” now enabled by default

- Removed SLP and AFP proxy support

- Removed type/creator extension mapping support

## Upgrading

1. Stop Netatalk 2.x

2. Install Netatalk 3

3. Manually recreate configuration in `afp.conf` and `extmap.conf`

4. Update your Netatalk start script (SMF, systemd, whatever...) to only start netatalk

5. Move `afp_voluuid.conf` and `afp_signature.conf` to the localstate directory (default `/var/netatalk/`), you can use `afpd -v` in order to find the correct path

6. Start Netatalk 3
