Got it. Right now the client is running the same patched Redhat 6.1 xen kernel as MGS and OSS node, I guess that's not the **patchless** client you mentioned.
Does patchless client means client running on un-patched kernel? Is there a way to build such client from the latest v2.1 code base? Or I can use official 2.0 release client to work with v2.1 MDS/OSS nodes? Thanks for the quick replies! -Jon.
