After my recent upgrade my Akonadi started to segfault and refuse to run. I finally just found out what the problem is in my case.

There have been a number of posts about problems with Akonadi but I don't think this particular issue has been adressed. I just wanted to make a note about it, maybe it will help someone else or at least it will serve as a reminder for myself :)

Anyway, I'm using ZFS for my /home and it turns out that Akonadi uses MySQL with the InnoDB database engine. The InnoDB engine defaults to using asynchronous i/o (aio) but ZFS on Linux does not support this feature. However, it can be turned off by adding/editing a file $HOME/.config/akonadi/mysql-local.conf like this:

Code:

[mysqld]
innodb_use_native_aio=0
