<font size=2 face="sans-serif">Hallo Stephan, </font><br><div><font size=2 face="sans-serif">the limit is not a hard coded limit
- technically spoken, you can raise it easily. </font><br><font size=2 face="sans-serif">But as always, it is a question of test
'n support .. </font><br><br><font size=2 face="sans-serif">I've seen customer cases, where the
use of much smaller amount of independent filesets generates a lot performance
issues, hangs ... at least noise and partial trouble .. </font><br><font size=2 face="sans-serif">it might be not the case with your specific
workload, because due to the fact, that you 're running already close
to 1000 ...</font><br><br><font size=2 face="sans-serif">I suspect , this number of 1000 file
sets - at the time of introducing it - was as also just that one
had to pick a number... </font><br><br><font size=2 face="sans-serif">... turns out.. that a general commitment
to support > 1000 ind.fileset is more or less hard.. because what uses
cases should we test / support</font><br><font size=2 face="sans-serif">I think , there might be a good chance
for you , that for your specific workload, one would allow and support
more than 1000 </font><br><br><font size=2 face="sans-serif">do you still have a PMR for your side
for this ? - if not - I know .. open PMRs is an additional ...but
could you please .. </font><br><font size=2 face="sans-serif">then we can decide .. if raising the
limit is an option for you .. </font><br><br><br><br><br><br><font size=2 face="sans-serif">Mit freundlichen Grüßen / Kind regards</font><br><br><font size=2 face="sans-serif"> <br>Olaf Weiser<br> <br>EMEA Storage Competence Center Mainz, German / IBM Systems, Storage Platform,<br>-------------------------------------------------------------------------------------------------------------------------------------------<br>IBM Deutschland<br>IBM Allee 1<br>71139 Ehningen<br>Phone: +49-170-579-44-66<br>E-Mail: olaf.weiser@de.ibm.com<br>-------------------------------------------------------------------------------------------------------------------------------------------<br>IBM Deutschland GmbH / Vorsitzender des Aufsichtsrats: Martin Jetter<br>Geschäftsführung: Martina Koederitz (Vorsitzende), Susanne Peter, Norbert

GPFS Independent Fileset Limit</font><br><font size=1 color=#5f5f5f face="sans-serif">Sent by:

and our GCS Partners from the Jülich Supercomputing Centre will soon be
hitting the current Independent Fileset Limit of 1000 on a number of our
GPFS Filesystems.</font><br><br><font size=3 face="Calibri">There are also a number of RFEs from other
users open, that target this limitation:</font><br><a href="https://www.ibm.com/developerworks/rfe/execute?use_case=viewRfe&CR_ID=56780"><font size=3 color=blue face="Calibri"><u>https://www.ibm.com/developerworks/rfe/execute?use_case=viewRfe&CR_ID=56780</u></font></a><br><a href="https://www.ibm.com/developerworks/rfe/execute?use_case=viewRfe&CR_ID=56780"></a><a href="https://www.ibm.com/developerworks/rfe/execute?use_case=viewRfe&CR_ID=120534"><font size=3 face="Calibri">https://www.ibm.com/developerworks/rfe/execute?use_case=viewRfe&CR_ID=120534</font></a><font size=3 color=blue face="Calibri"><u><br></u></font><a href="https://www.ibm.com/developerworks/rfe/execute?use_case=viewRfe&CR_ID=106530"><font size=3 color=blue face="Calibri"><u>https://www.ibm.com/developerworks/rfe/execute?use_case=viewRfe&CR_ID=106530</u></font></a><br><a href="https://www.ibm.com/developerworks/rfe/execute?use_case=viewRfe&CR_ID=85282"><font size=3 color=blue face="Calibri"><u>https://www.ibm.com/developerworks/rfe/execute?use_case=viewRfe&CR_ID=85282</u></font></a><font size=3 face="Calibri"><br></font><br><font size=3 face="Calibri">I know GPFS Development was very busy fulfilling
the CORAL requirements but maybe now there is again some time to improve
something else. </font><br><br><font size=3 face="Calibri">If there are any other users on the list
that are approaching the current limitation in independent filesets, please
take some time and vote for the RFEs above.</font><br><br><font size=3 face="Calibri">Many thanks in advance and have a nice
weekend.</font><br><font size=3 face="Calibri">Best Regards,</font><br><font size=3 face="Calibri">Stephan Peinkofer</font><br><br><tt><font size=2>_______________________________________________<br>gpfsug-discuss mailing list<br>gpfsug-discuss at spectrumscale.org<br></font></tt><a href="http://gpfsug.org/mailman/listinfo/gpfsug-discuss"><tt><font size=2>http://gpfsug.org/mailman/listinfo/gpfsug-discuss</font></tt></a><tt><font size=2><br></font></tt><br><br></div><BR>
