<p class="MsoNormal">Hi,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I’m running a simple AFR setup, thouch currently with only one backend, and 2 tcp clients. Version is 3.0.0 from jan 20.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Basically one client is writing a large number of files, continuously, and the other client is reading.
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I have a growing problem with lookup “conflicts”, resulting in files being listed in directories but where reads are returning “-1 (No such file…”.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Restarting the client does not solve the conflict, but restarting the server does and the files becomes available again.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The filesystem is a 5TB XFS hw raid-5 with around 150k files.<o:p></o:p></p>
