Hi, I'm working on a project where we are recording data directly from our sensor platform to a set of HDF5 files. We recently ran into an issue where the system lost power and now I cannot open the HDF5 files. The data appears to be there, but I'm guessing some of the metadata is corrupt/out of date. We are currently using v1.8.x of the HDF5 library, mostly with the C++ API, but with some C API calls as well.
A few questions: 1) What can I do to recover this data? I've started looking at the HDF5 file format, but any pointers would be appreciated. 2) Is there anything I can do in the future to avoid file corruption from power loss/crashing processes? We already periodically call the flush() method. 3) I saw that metadata journaling is on the roadmap at v1.10, but I also saw mentions that that release was targeted for 2009 - is there an update on when this will be available? Many thanks - I'm a great fan of HDF5 and I don't want to go back to writing flat binary files! -John ----------------- John Kua Research Scientist Applied Nuclear Physics Lawrence Berkeley National Laboratory
