File ./ib_logfile101: 'aio write' returned OS error 122
I'm trying to install MySQL 5.6.14 on Ubuntu 12.04 Desktop:
$ scripts/mysql_install_db --no-defaults --force \
--explicit_defaults_for_timestamp --datadir=/tmp/data
And I'm getting:

What this could be? How to solve?
Answer
It means the filesystem your using doesn't support aio. You can tell this to innodb by adding the following line to my.cnf:
innodb_use_native_aio=0
With this in my.cnf MySQL should be able to start.
