<html><body><p>Hi Luke,<br><br>The short answer is yes, when the file is created on the home, it is a 'brand new' creation that will conform to any and all new placement policies that you set on the home site. So if you are using NFS in the relationship, then it is simply created just like any other file is created over NFS. The same goes when using GPFS to the home cluster...<br><br>Dean<br>IBM Almaden Research Center<br><br><br><img width="16" height="16" src="cid:1__=07BBF5F0DFFA84CB8f9e8a93df938690918c07B@" border="0" alt="Inactive hide details for Luke Raimbach ---02/24/2016 06:05:43 AM---Hi All, I have two GPFS file systems (A and B) and an AFM S"><font color="#424282">Luke Raimbach ---02/24/2016 06:05:43 AM---Hi All, I have two GPFS file systems (A and B) and an AFM Single Writer relationship: /fsB/cache wri</font><br><br><font size="2" color="#5F5F5F">From: </font><font size="2">Luke Raimbach <Luke.Raimbach@crick.ac.uk></font><br><font size="2" color="#5F5F5F">To: </font><font size="2">gpfsug main discussion list <gpfsug-discuss@gpfsug.org></font><br><font size="2" color="#5F5F5F">Date: </font><font size="2">02/24/2016 06:05 AM</font><br><font size="2" color="#5F5F5F">Subject: </font><font size="2">[gpfsug-discuss] AFM and Placement Policies</font><br><font size="2" color="#5F5F5F">Sent by: </font><font size="2">gpfsug-discuss-bounces@spectrumscale.org</font><br><hr width="100%" size="2" align="left" noshade style="color:#8091A5; "><br><br><br><tt>Hi All,<br><br>I have two GPFS file systems (A and B) and an AFM Single Writer relationship: /fsB/cache writes back to /fsA/home<br><br>I have a placement policy which sets extended attributes on file creation in /fsB/cache.<br><br>When I create a new file in /fsB/cache/new.file and it is pushed back by AFM to /fsA/home/new.file, can the home fileset apply a different placement policy to add or modify extended attributes?
