An example and 'real' use case to Svens answer: The term 'local' might indeed a bit misleading. The posix file system option basically lets you use anything posix compliant. For instance I am using a cluster file system called StorNext in our company - witch is very well suited for use with oVirt. Without POSIX, I could not have used it.

Posix enables usage of GlusterFuseFS. However, it might be the case the replica 3 is only needed when using FuseFS [1], independent from the fact of using Gluster and Compute on the same host. > > HTH > [1] http://www.mail-archive.com/[email protected]/msg22416.html -- Daniel Helgenberger m box bewegtbild GmbH P: +49/30/2408781-22 F: +49/30/2408781-10 ACKERSTR. 19 D-10115 BERLIN www.m-box.de www.monkeymen.tv Geschäftsführer: Martin Retschitzegger / Michaela Göllner Handeslregister: Amtsgericht Charlottenburg / HRB 112767 _______________________________________________ Users mailing list [email protected] http://lists.ovirt.org/mailman/listinfo/users
