This is the chapter of the MemberManual that describes how to install the OpenAFS client on Fedora.
The bulk of this page reflects Fedora 23. It also contains some potentially helpful, but unverified information, from an earlier version of this page, prefaced with "OLD:"
Introduction
There are different sets of RPMS available for OpenAFS. The easiest to install and maintain across system updates is probably a copr repo. Enable it with:
dnf copr enable jsbillings/openafs
Install OpenAFS RPMS
Next, install the appropriate openafs kernel module. Check your currently-running kernel with uname -a, then substitute your version into this command:
dnf install kmod-openafs-[PACKAGE.VERSION]-[KERNEL.VERSION]
Dnf may default to the wrong kernel module. Check closely that the version exactly matches your running kernel. If not, manually type the entire package and kernel version numbers.
Then, install the rest of the openafs rpm files:
dnf install openafs openafs-kmdl openafs-authlibs openafs-docs openafs-client krb5-workstation openafs-kmod-docs
Configuration
Change the home cell in /etc/openafs/ThisCell to hcoop.net.
Start the openafs client once with systemctl start openafs-client.service
Enable the openafs client to run on boot with systemctl enable openafs-client.service
- Run kinit and type your password
Make sure that the openafs client is running with systemctl status openafs-client.service
- Run "klist" just to make sure that you have a valid token.
- Run aklog - if this works you should be able to see /afs/hcoop.net.
And that's it!
OLD: Your machine should automatically pick up new versions of the openafs kernel module when you do updates.
OLD: Troubleshooting
If you get an error like "aklog: unable to obtain tokens for cell hcoop.net (status: 11862790)" it may mean that your router is blocking SRV requests. If you're running djbdns locally (used by lots of operating systems for embedded devices, such as OpenWrt), make sure that the line filterwin2k is commented out in /etc/dnsmasq.conf, or whatever the configuration file is on your machine.
If you get messages saying things like "libafs can't be found" when you try to start the client, you probably installed a version of openafs-kmdl that doesn't match your running kernel. Use yum to remove the openafs RPM packages and try again.
