Mark,<br>
<br>
Thank you for taking the time to comment, I genuinely appreciate it!<br>
<br>
I will digest and look at the mmfind examples (to be honest, didn't know it was a thing.....).<br>
<br>
Everything I know about Spectrum Scale (and Spectrum Archive) has been self taught so...... I'm pretty sure I'm missing Soooooooooo much useful info!<br>
<br>
I wish there was like a dummies guide (I've read the redbooks and admin guides as best I can but I know my knowledge is patchy at best)!<br>
<br>
Once digested I may, or may not, have further questions but I genuinely thank you for your assistance.<br>
<br>
Owen.<br>

The pithy ruminations from Owen Morgan on <br>
[[External] [gpfsug-discuss] Policy Rules Syntax to find files older than X days excluding weekends in the calculation....] were:
<br>
=> Hi Everyone, <br>
=> <br>
=> First question from me I appreciate this is policy engine thing as <br>
=> opposed to more fundamental Spectrum Scale so hope its ok! <br>
<br>
It's great. <br>
<br>
=> <br>
=> I'm trying to find a 'neat' way within a couple of policy rules to <br>
=> measure different time intervals (in days) but solely interested in WEEK <br>
=> DAYS only (ie delete files older than X week days only). <br>
<br>
<br>
Policy SQL syntax gives me a headache. For this kind of task, I find <br>
that mmfind is your friend -- it's in the "examples" source dir within <br>
/usr/lpp/mmfs. Trivial to compile & install. Easier to debug, and it <br>
will generate the SQL. <br>
<br>
=> <br>
=> An example is one of the rules a team would like implemented is delete <br>
=> all files older than 10 business days (ie week days only. We are <br>
<br>
What about "delete all files older than 12 calendar days" -- by <br>
definition, those files are older than 10 business days as well. <br>
<br>
=> ignoring public holidays as if they don't exist). Followed by a separate <br>
=> rule for a different folder of deleting all files older than 4 business <br>
=> days. <br>
<br>
Or, older than 6 calendar days. <br>
<br>
Or, run this nightly: <br>
<br>
#! /bin/bash <br>
dateOffset=0 <br>
if [ `date '+%u'` -le 4 ] ; then <br>
# Mon=1, Tue=2, Wed=3, Thu=4 <br>
# <br>
# For a file to be more than 4 business days old on-or-before the <br>
# 4th day of the week, it must span the weekend, so offset the number <br>
# of required days in the file age <br>
dateOffset=2 <br>
fi <br>
<br>
mmfind -mtime $((4 + $dateOffset)) /path/to/Nuke/After/4/Days -xarg rm -f <br>
<br>
<br>
=> <br>
=> Thanks in advance, <br>
