Greetings all.
I have a issues using the libaio engine on Ubuntu-13.10. FIO version 2.1.8 is installed and runs fine if I leave the -ioengine option out of my configuration (it defaults to ioengine sync). When I try and use -ioengine=libaio I receive the errors
fio: engine libaio not loadable
fio: failed to lead engine libaio
I have use these identical workloads on Suse 11, RH6, and Cent OS systems with no issue. And even after specifically installing libaio on Ubuntu I still see these issues.
apt-get install libaio1
Any ideas? I'm suspecting this is user error but I can't see where I went wrong.
You need libaio-devel (or whatever the package is called) installed,
otherwise fio can't build with libaio enabled. Watch the configure
output, it'll tell you what it detects:
$ ./configure
[...]
Linux AIO support yes
This is also detailed in the "Building" section in the README that came
with fio.
