Placement policies and copies</font><br><font size=1 color=#5f5f5f face="sans-serif">Sent by:

2.<br><br>I now have some data Id like to have which only has 1 copy made. I know
that files and directories don't inherit 1 copy based on their parent.<br><br>Can I do this with a placement rule to change the number of copies to 1?<br><br>I don't really want to have to find the file afterwards and fix up as that
requires an mmrestripefs to clear the second copy.<br><br>Or if I have a pool which only has nsd disks in a single failure group
and use a placement policy for that, would that work? Or will gpfs forever
warn me that due to fs changes I have data at risk?<br><br>Thanks<br><br>Simon<br>_______________________________________________<br>gpfsug-discuss mailing list<br>gpfsug-discuss at spectrumscale.org<br></font></tt><a href="http://gpfsug.org/mailman/listinfo/gpfsug-discuss"><tt><font size=2>http://gpfsug.org/mailman/listinfo/gpfsug-discuss</font></tt></a><tt><font size=2><br><br></font></tt><br><BR>
