Dear Marc,
If you "must" exceed 1000 filesets because you are assigning each project to
its own fileset, my suggestion is this:
Yes, there are scaling/performance/manageability benefits to using mmbackup
over independent filesets.
But maybe you don't need 10,000 independent filesets --
maybe
All, don’t forget registration ends on the early side for this event due to
background checks, etc.
As noted below:
IMPORTANT: September 1st is the deadline to register for HPCXXL and the GPFS
Day.
Hope you’ll be able to attend!

Hi Aaron,
I just searched the core GPFS source code. I didn't find TCP_QUICKACK

This is a question mostly for the devs. but really for anyone who can answer.
Does GPFS use the TCP_QUICKACK socket flag on Linux?
I’m debugging an IPoIB problem exacerbated by GPFS and based on the packet
captures it seems as though the answer might be yes, but I’m curious if GPFS is

as Dominic said.. .. your are absolutely
right .. for mmbackup you need dedicated inode spaces .. so "independent"
filesets .. (in case I you wanna be able to mmbackup on a fileset
level or multiple mmbackup's in parallel .. )From:

Dear Marc,
OK, so let’s give it a try:
[root@datdsst100 pr74qo]# mmlsfileset dsstestfs01
Filesets in file system 'dsstestfs01':
Name StatusPath
root Linked/dss/dsstestfs01
...
quota_test_independent Linked
there's no mm* command to get it cluster
wide.. you can use fileheat and policy
engine to identify most active files .. and further more... combine
it with migration rules ... to replace those files .. please note.. files, that are accessed
very heavily but all requests answered out of pagepol
