This one has been on my list a long time so I figured I'd ask here first before<br>
I open an apar or request an enhancement (most likely).<br>
<br>
Is there a way using the policy engine to determine the following?<br>
<br>
-metadata replication total/current <br>
-unbalanced file <br>
<br>
Looking to catch things like this that stand out on my filesystem without<br>
having to run several hundred million 'mmlsattr's. <br>
<br>
metadata replication: 1 max 2 <br>
flags: unbalanced<br>
