Thanks Andreas,
that explains that.
So the warning can be made to go by changing line 183 in lustre-info.pl from
printf(", %s=%5.1f R/s",$type,$stats->{$type}/$slice)
to be
if (exists $stats->{$type})
{ printf(", %s=%5.1f R/s",$type,$stats->{$type}/$slice); }
(patch attached)

Note the 'Use of uninitialized value in division...' errors. Looking at
the code it seems the value for 'setattr' is missing from the stats file
for some of our OSTs. Looking at the stats file, indeed the setattr line
is missing for some OSTs.
Has anyone seen this before? What could have caused this?
The statistics code for OBD devices is generic. For operations that have never been done on a
particular target there is no stats value printed. Otherwise, the "stats" file would be
60 lines long and mostly be filled with counters that are all "0".
Cheers, Andreas
