1) Message boards : News : BHDB application (Message 2755) Posted 27 Mar 2018 by [DPC]Blah.NET Post: I've been having the "exceeded disk limit" problems as well, so I decided to look a little deeper into what the application is actually doing while it is being run. You probably already know this , but I was surprised by the fact that the app seems to be writing duplicate copies of several results files, including one set of files that can easily become 800-900MB+ (data1.dat2 and data1.dat3). Example of duplicate files (in the "slots" directory of a BHDB3 task in progress): # sha256sum -b data.dat 9e4f9639efb55652dd12704758fca1e5ff84f36b1f053fd7deefdc75cd3f9fb9 data0.dat 13fa73e139c7516e11c061fba4ce5120ee5a89e48d9f311de770aa52ee4a3d80 data0.dat2 13fa73e139c7516e11c061fba4ce5120ee5a89e48d9f311de770aa52ee4a3d80 data0.dat3 ee8ebfbc970f3b22336e87fc05c83166d795a7707a54bbb6d39774a89c12e5ec data1.dat d0af02bb3d08ae0042ce3854794bcf5f6592775cb9d9fe702c32c5ca5fa62a7f data1.dat2 d0af02bb3d08ae0042ce3854794bcf5f6592775cb9d9fe702c32c5ca5fa62a7f data1.dat3 cbf374f3985ddaa108b17a4f3dc7d69678f6616a64f04d7424886c2d2cf81911 data2.dat 6c1d6146828c22d3038ee65542e9d50fb5d5ce3b2f9ad33a87cd77cbb8cdba3b data2.dat2 6c1d6146828c22d3038ee65542e9d50fb5d5ce3b2f9ad33a87cd77cbb8cdba3b data2.dat3 # ls -1sh data.dat* 4.0K data0.dat 1.6M data0.dat2 1.6M data0.dat3 364K data1.dat 362M data1.dat2 362M data1.dat3 4.0K data2.dat 1.5M data2.dat2 1.5M data2.dat3 I don't want to be rude, but is it really necessary to write these duplicate *.dat3 files? If these duplicates are not really needed, I think it should be fairly simple to prevent the failure a lot of the WU's by fixing the code to not generate these big duplicate files.
