That is what I would have guessed until I took a look at my own MDT. Sure enough, I have the directories /O/1/d[0-31] and each one seems to have 3 files that are about 3.5MB each (along with some other smaller ones). Here is what one of those directories looks like: debugfs: ls -l /O/1/d14 16777293 40700 (2) 0 0 4096 20-Apr-2015 14:09 . 16777278 40755 (2) 0 0 4096 13-May-2014 16:51 .. 58129 100644 (1) 0 0 8256 13-May-2014 16:51 14 58162 100644 (1) 0 0 8256 13-May-2014 16:51 46 58197 100644 (1) 0 0 8256 13-May-2014 16:51 78 58237 100644 (1) 0 0 37632 13-May-2014 19:28 110 58271 100644 (1) 0 0 38464 13-May-2014 19:28 142 58305 100644 (1) 0 0 37888 13-May-2014 19:28 174 58343 100644 (1) 0 0 37184 13-May-2014 19:28 206 58396 100644 (1) 0 0 37312 13-May-2014 19:28 238 58429 100644 (1) 0 0 36160 13-May-2014 19:28 270 12824 100644 (1) 0 0 3623232 20-Apr-2015 14:09 43150 12915 100644 (1) 0 0 3800960 20-Apr-2015 14:09 43182 12954 100644 (1) 0 0 3769216 20-Apr-2015 14:09 43214 The three large files seem to have been created the last time the MDT was mounted. The timestamps for the other smaller files coincides with the Lustre upgrade we performed last year. But I am not sure what is contained in these files. Radu: Are the timestamps for all of your files the same? Or is the system gradually accumulating them over time for some reason? -- Rick Mohr Senior HPC System Administrator National Institute for Computational Sciences http://www.nics.tennessee.edu _______________________________________________ lustre-discuss mailing list [email protected] http://lists.lustre.org/listinfo.cgi/lustre-discuss-lustre.org
