<font size=3 face="Arial">I recently compiled the 3.10-5 client from source
on a few PPC64 systems running RHEL 7.3. They are mounting a Gluster volume
which is hosted on more traditional x86 servers.</font>
<br>
<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>
<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>
<br>
<br><font size=3 face="Arial">Using a pre-compiled 3.10-5 package on an
x86 client doesn't show the issue.</font>
<br>
<br><font size=3 face="Arial">I poked around bugzilla but couldn't seem
to find anything which matches this.</font>
