Subject: Re: Need help debugging NFS issues new to 4.20 kernel

Message-ID: <ufapnrmbhyf.fsf@epithumia.math.uh.edu> (raw)
In-Reply-To: <e8887651e91b1d0110cab2330a03e3e3ccef742b.camel@hammerspace.com> (Trond Myklebust's message of "Sat, 16 Feb 2019 14:46:45 +0000")
Sadly, after a bit more testing I find that 4.20.10 with that patch
applied still exhibits the problem. Just found a machine where NFS hung
up just six minutes after the user logged in. As always: nothing is
logged to the client or the server. I turned on the tracing as
requested previously and see what I think it just the same sequence as
before. Please let me know if there is any other information I can
provide. Right now I'm going to build 4.20.10 with my previously posted
revert patch applied and roll that out to the same 50 hosts and see how
it fares.
