Bruce Fields" Cc: Eric Sandeen , linux-nfs@vger.kernel.org, xfs@oss.sgi.com FYI, I've now managed to reproduce the issue. I haven't had time to dig deeper, but it smells a lot like a callback path issue. Can you send the recursion fix to Linus ASAP and I'll send you a patch to turn the nopnfs option into a pnfs one, so we're at least doing fine for 4.0 in any case. I hope to debug this and may even have a real fix soon, but so far I don't know how long it will take. _______________________________________________ xfs mailing list xfs@oss.sgi.com http://oss.sgi.com/mailman/listinfo/xfs
