[Storage-research-list] UPDATE: LANL fsstats (Filesystem Statistics) data release

[McClelland, Meghan W]

These data files have been updated.  Please download the files again to get correct entries per directory data.  The rest of the information in each file remains unchanged.

More details:

The "directory size (entries)" histogram was incorrect - everything was always 1 entry. This is fixed - thanks to Yifan Wang and the CMU PDL team for finding and reporting this issue!

All filesystems used to have:
-------------
histogram,directory size (entries)
count,<some#>,items
average,1.000000,ents
min,1,ents
max,1,ents
bucket min,bucket max,count,percent,cumulative pct,val count,percent,cumulative pct
0,1,<some#>,1.000000,1.000000,<some#>,1.000000,1.000000
------------------------

The histogram is now updated to reflect the correct information.

If you have any questions about this fix or these data in general, please contact meghan at lanl.gov<mailto:meghan at lanl.gov>

To enable computer science research Los Alamos National Laboratory (LANL) is releasing static file tree data (fsstats) for some of our parallel filesystems. These data include aggregate information on capacity, file and directory sizes, filename lengths, link counts, etc. The fsstats cover 9 anonymous parallel filesystems ranging from 16 TB to 439 TB total capacity used and file counts range from 2,024,729 to 43,605,555.

The following sets of data are provided by Los Alamos National Laboratory under universal release to any computer science researcher to use to enable computer science work.

If you use these data in your research please recognize Los Alamos National Laboratory for providing these data.

More information and the data may be found on the fsstats data release page:
