[jboss-jira] [JBoss JIRA] (WFLY-6406) Artemis AIO journal fails on zfsonlinux ZFS filesystem

[Dominik Pospisil (JIRA)]

    [ https://issues.jboss.org/browse/WFLY-6406?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13179038#comment-13179038 ] 

Dominik Pospisil commented on WFLY-6406:
----------------------------------------

It turns out that zfsonlinux does support Async IO since 6.4 but it does not support direct io (O_DIRECT) yet. According to libaio docs, it requires O_DIRECT.

Maybe the AIOSequentialFileFactory.isSupported() should be enhanced to perform some more thorough check than just checking if native lib was loaded as it does as of now.

> Artemis AIO journal fails on zfsonlinux ZFS filesystem. According to zfsonlinux docs libaio should be supported. 
> I guess that the initialization should work or failback to NIO.
