<div dir="ltr">Hello,<div>just to clarify. Customer need is very easy: Deny storing selected files extension in specific filesets.</div><div>I also don't like the way to direct placement to metadata only pool. I also know that small filse can actually be stored there.</div>
<div>I will appreciate more help how to make it. I don't think that expalanation to customer that his need is stupid, is a good approach to the customer.</div><div>If there is or not .divx extension is not important, we care about GPFS stuff and the extensions were selected by customer.</div>

To demonstrate why this is a wack-a-mole exercise, as a user of your<br>
system I will just save in iPod friendly format, all my audio AAC<br>
encoded in .m4a files, all my video H.264 encoded in .m4v files, and my<br>
audiobooks in .m4b format :-)<br>
<br>
I would further note that it is rather trivial to pick a random<br>
extension say .sdf and associate that with just about any program, most<br>
of which examine the contents of the file and don't rely on the<br>
extension.<br>
<br>
Further noting if you are continuing in your wack-a-mole exercise I<br>
could use .divx which you have conveniently not blocked.<br>
<br>
Finally being the resourceful sort I will just embed it all in a PDF, or<br>
word document, or powerpoint, or ...<br>
<br>
I don't know exactly what your customer is expecting, but this sounds<br>
like a management idea, with little understanding of how things work in<br>
the real world.<br>

To further the wack-a-mole problem:<br>
If you set those extensions to be in the system pool and assume the<br>
system pool has no data-disks, it is still possible for GPFS 3.5 to<br>
create a file in the system pool if one is utilizing the<br>
small-files-in-metadata feature (whatever it's called now) and if the<br>
file is 0-3.9K in size where it will be stored in the xattrs.<br>
So, this only works for mp3's >3.9K :) Probably OK for mp3's but not<br>
if, say, you wanted to restrict .txt files, which are often that<br>
small.<br>
