<p><font face="Arial" size="2">I am running several clients writing to local
disk that are setup to replicate data to N glusterfs server processes that
use NFS for storing this data. I have the following
questions:</font></p>
<p><font face="Arial" size="2">1. Does every write of a process to a local
directory managed by glusterfs client involve syncronous replication of data
to glusterfs server?</font></p></div></blockquote>
<div>yes. it involves synchronous replication.
<br><br>glusterfs--mailine--3.0--patch-621 (onwards) in our source
repository has an AFR feature called quick-unwind, which would make
replication asychronous.<br><br></div>

<p><font face="Arial" size="2">2. Is it possible that if NFS is slow on the
glusterfs server side, then writing to local disk of a process on the
glusterfs client's machine would block?</font></p></div></blockquote>
<div>yes. fops on glusterfs will block.<br></div>
