<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D">I’m having some issues where a simple ILM list policy never completes, but I have yet to open a PMR or enable additional logging. But I was wondering if there
are known reasons that this would not complete, such as when there is a symbolic link that creates a loop within the directory structure or something simple like that.<o:p></o:p></span></p>

<p class="MsoNormal" style="margin-bottom:12.0pt"><span style="font-size:10.0pt;font-family:"Arial",sans-serif">Well I'm glad we followed Mr. S. Holmes dictum which I'll paraphrase... eliminate the impossible and what remains, even if it seems improbable,
must hold.</span><br>

<span style="font-size:10.0pt;font-family:"Arial",sans-serif">BTW - you may want to look at mmclone. Personally, I find the doc and terminology confusing, but mmclone was designed to efficiently store copies and near-copies of large (virtual machine) images.
Uses copy-on-write strategy, similar to GPFS snapshots, but at a file by file granularity.</span><br>
<br>
<span style="font-size:10.0pt;font-family:"Arial",sans-serif">BBTW - we fixed directories - they can now be huge (up to about 2^30 files) and automagically, efficiently grow and shrink in size. Also small directories can be stored efficiently in the inode.
The last major improvement was just a few years ago. Before that they could be huge, but would never shrink. <br>
