<div dir="ltr">Looks like it is an issue with architecture compatibility in RPC layer (ie, with XDRs and how it is used). Just glance the logs of the client process where you saw the errors, which could give some hints. If you don't understand the logs, share them, so we will try to look into it.<div><br></div><div>-Amar<br><div class="gmail_extra"><br><div class="gmail_quote">On Wed, Sep 20, 2017 at 2:40 AM, Walter Deignan <span dir="ltr"><<a href="mailto:WDeignan@uline.com" target="_blank">WDeignan@uline.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><font size="3" face="Arial">I recently compiled the 3.10-5 client from source

which is hosted on more traditional x86 servers.</font>

<br><font size="3" face="Arial">Everything seems to be working properly except
for creating new directories from the PPC64 clients. The mkdir command
gives a "Input/output error" and for the first few minutes the
new directory is inaccessible. I checked the backend bricks and confirmed
the directory was created properly on all of them. After waiting for 2-5
minutes the directory magically becomes accessible.</font>

<br><font size="3" face="Arial">This inaccessible directory issue only appears
from the client which created it. When creating the directory from client
#1 I can immediately see it with no errors from client #2.</font>

x86 client doesn't show the issue.</font>
