[Ocfs2-users] Any chance using OCFS2 as a distributed file system (without a shared disk)?

[Christian Baun]

Thank's a lot for your kind help! :-)

For my project, I will try a distributed file system like Lustre, PVFS or HDFS, because it is very likely that I will need more than 2 nodes in the future.

Best Regards,

I know of a few people that are using this setup on 2 node web clusters and it works very well for them. However I don't know if you can run this with more than 2 nodes.
