Hi, Akonadi server fails to start on Kubuntu 12.04 amd64 when I try to start KMail and home is in AFS. First I thougt that the folders ~/.config/akonadi and ~/.local/share/akonadi might need to be outside of AFS so I moved them to the local hard drive and added symbolic links, but the problem is still the same. When looking at the akonadi-selftest-report log the problem seem to start at "Test 10" which says "Akonadi control process not registered at D-Bus.". I would appreciate any hints on how to dig further into the problem to try to solve it, e.g. how do I try to run some of the steps manually with more verbose logging of what goes wrong? Akonadi Server Self-Test Report =============================== Test 1: SUCCESS -------- Database driver found. Details: The QtSQL driver 'QMYSQL' is required by your current Akonadi server configuration and was found on your system. File content of '/afs/mydomain/myuser/.config/akonadi/akonadiserverrc': [%General] Driver=QMYSQL [QMYSQL] Name=akonadi Host= Options="UNIX_SOCKET=/afs/mydomain/myuser/.local/share/akonadi/socket-ledig/mysql.socket" ServerPath=/usr/sbin/mysqld-akonadi StartServer=true Test 2: SUCCESS -------- Akonadi is not running as root Details: Akonadi is not running as a root/administrator user, which is the recommended setup for a secure system. Test 3: SUCCESS -------- MySQL server found. Details: You have currently configured Akonadi to use the MySQL server '/usr/sbin/mysqld-akonadi'. Make sure you have the MySQL server installed, set the correct path and ensure you have the necessary read and execution rights on the server executable. The server executable is typically called 'mysqld'; its location varies depending on the distribution. Test 4: SUCCESS -------- MySQL server is executable. Details: MySQL server found: /usr/sbin/mysqld Ver 5.5.32-0ubuntu0.12.04.1 for debian-linux-gnu on x86_64 ((Ubuntu)) Test 5: SUCCESS -------- No current MySQL error log found. Details: The MySQL server did not report any errors during this startup. The log can be found in '/afs/mydomain/myuser/.local/share/akonadi/db_data/mysql.err'. Test 6: SUCCESS -------- MySQL server default configuration found. Details: The default configuration for the MySQL server was found and is readable at <a href='/etc/akonadi/mysql-global.conf'>/etc/akonadi/mysql-global.conf</a>.

Filesystem Size Used Avail Use% Mounted on /dev/sda3 213G 192M 202G 1% /local This is how I have created the symbolic links: $ mkdir -p /local/myuser/.local/share $ mv ~/.local/share/akonadi /local/myuser/.local/share/ $ ln -s /local/myuser/.local/share/akonadi ~/.local/share/ $ mkdir -p /local/myuser/.config $ mv ~/.config/akonadi /local/myuser/.config/ $ ln -s /local/myuser/.config/akonadi ~/.config/ $ ls -l ~/.local/share/akonadi lrwxr-xr-x 1 myuser mygroup 34 Oct 16 09:01 /afs/mydomain/myuser/.local/share/akonadi -> /local/myuser/.local/share/akonadi $ ls -l ~/.config/akonadi lrwxr-xr-x 1 myuser mygroup 29 Oct 16 09:01 /afs/mydomain/myuser/.config/akonadi -> /local/myuser/.config/akonadi
I have now also tried to move the whole folders ~/.config ~/.local ~/.kde from AFS to the local harddrive (ext4) but the problem is the same. Is it not strange that it complains with the following: stderr: "Could not open required defaults file: /afs/mydomain/myuser/.local/share/akonadi/mysql.conf Fatal error in defaults handling. Program aborted " because the file /afs/mydomain/myuser/.local/share/akonadi/mysql.conf is there and is readable both by myuser and by root).
You said the afs file is a symlink to a local file, right? Maybe MySQL simply refuses to read anything from a network filesystem. Anyway, this is obviously a problem in MySQL not in Akonadi, so closing as UPSTREAM. Please take this to MySQL forum/mailing list, maybe they will be able to help you. You can also try with PostgreSQL, maybe they support AFS.
Sorry for being stupid, but how do I change so that Akonadi uses PostgreSQL instead of MySQL? I have now installed the packet "akonadi-backend-postgresql" but if I try to remove the package "akonadi-backend-mysql" the system also wants to remove akonadi-server. Any other database management system would be fine too if PostgreSQL is not a suitable.
You don't have to remove the MySQL package. Stop Akonadi (akonadictl stop), start Akonadi Server KCM (kcmshell4 akonadi_server), select PostgreSQL driver and configure it. Then delete ~/.local/share/akonadi/db_data and ~/.local/share/akonadi/file_db_data and ~/.config/akonadi. Then start Akonadi (akonadictl start) and you should be running against PostgreSQL. You will have to recreate all settings though and Akonadi will have to download everything again. We only support MySQL, PostgreSQL and SQLite backends, but SQLite is NOT recommended due to miserable performance.
