We have a cluster set up with 60 nodes. We have a folder with the striping count set to 20. We loaded up two folders with a large number of small files. I know the bigger the file the better the more Lustre shines but we have multiple things to test and this is the first. According to "lfs df -h" there is a total disk use of 76.3G. I ran "du -sh" at the top level of the folders and am now at 45 minutes run time without a result yet. Top only shows du taking between 3 and 5% cpu time and 1% of memory.
Does anyone know what causes this? Shouldn't the server be able to examine the MDS to sum the space used? At worst wouldn't the first object on the stripe return the total file size if it isn't kept on the MDS?
