[Ocfs2-devel] OCFS2 support which architectures and can the cluster work under mixed architectures?

[Gang He]

Hello Junxiao,

Thank for your information.

Is OCFS2 file system proved (or fully tested) only on x86 and x86_64 platform? my understanding is right? that means we should not recommend OCFS2 file sytem to the customers for being used under the other architectures in production before we do a full testing?


Thanks
Gang
