Jiri Daněk created ARTEMIS-2184:
-----------------------------------
Summary: AIO does not start on tmpfs: RuntimeException:
ActiveMQNativeIOError[errorType=NATIVE_ERROR_CANT_INITIALIZE_AIO message=Cannot
open file:Invalid argument]
Key: ARTEMIS-2184
URL: https://issues.apache.org/jira/browse/ARTEMIS-2184
Project: ActiveMQ Artemis
Issue Type: Bug
Components: Broker
Reporter: Jiri Daněk
{{O_DIRECT}} flag is unsupported on tmpfs. There were attempts to add it to
Linux kernel, which were rejected, as I understand it.

http://linux-kernel.2935.n7.nabble.com/PATCH-support-O-DIRECT-in-tmpfs-ramfs-td201650.html
Is there a valid usecase for anyone wanting to put the journal on a ramdisk? My
thinking was that I had only network storage available (GlusterFS as / and a
NFS mount) and I wanted to avoid any network i/o when running broker (broker
tests), to make it faster.
Does AIO require O_DIRECT? Is it possible to use AIO on ramdisk, tmpfs?
