<p style="margin-top:0;margin-bottom:0">I am trying to migrate files I know are not in use off of the full OST that I have using lfs migrate. I have verified up and down that the files I am moving are on that OST and that after the migrate lfs getstripe indeed
shows they are no longer on that OST since it's disabled in the MDS.</p>
<p style="margin-top:0;margin-bottom:0"><br>
</p>
<p style="margin-top:0;margin-bottom:0">The problem is, the used space on the OST is not going down.</p>
<p style="margin-top:0;margin-bottom:0"><br>
</p>
<p style="margin-top:0;margin-bottom:0">I see one of at least two issues:</p>
<p style="margin-top:0;margin-bottom:0">- the OST is just not freeing the space for some reason or another ( I don't know)</p>
<p style="margin-top:0;margin-bottom:0">- Or someone is writing to existing files just as fast as I am clearing the data (possible, but kind of hard to find)</p>
<p style="margin-top:0;margin-bottom:0"><br>
</p>
<p style="margin-top:0;margin-bottom:0">Is there possibly something else I am missing? Also, does anyone know a good way to see if some client is writing to that OST and determine who it is if it's more probable that that is what is going on?</p>
