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.
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.
Using a pre-compiled 3.10-5 package on an x86 client doesn't show the issue.
I poked around bugzilla but couldn't seem to find anything which matches this.
