Hi All,
I think we *may* be able to wrap this saga up… ;-)
Dave - in regards to your question, all I know is that the tail end of the log
file is “normal” for all the successful pool migrations I’ve done in the past
few years.
It looks like the hard links were the problem. We have one group
Hi Marc,
Two things:
1. I have a PMR open now.
2. You *may* have identified the problem … I’m still checking … but files with
hard links may be our problem. I wrote a simple Perl script to interate over
the log file I had mmapplypolicy create. Here’s the code (don’t laugh, I’m a

Hi All,
First off, I can open a PMR for this if I need to. Second, I am far from an
mmapplypolicy guru. With that out of the way … I have an mmapplypolicy job
that didn’t migrate anywhere close to what it could / should have. From the
