This will remove a lot of old cruft and update -the input files. This effort was started in January 2015 and should be -completed within the year. +This is based off the ancient 'vol' branch and is wildy +out of sync with develop. You will not be able to move +the RADOS VOL connector built here to HDF5 1.12.0 without +a lot of surgery. The rados_vol branch in this repository +is kept in sync with develop and is probably the one +you want for that. -This branch tracks the trunk. +Note that this is a dead branch, so no effort has been +made to keep the MANIFEST sane, etc. -Dana Robinson and Allen Byrne are the owners of this branch. +************ +* BUILDING * +************ -This branch should be closed when the bulk of the autotools work is -complete and has been merged into the trunk and 1.8 branch. This -work should be completed by mid-2015. +RADOS: + +The code for the RADOS VOL connector lies entirely in +the H5VLrados* files in the src directory. The connector +is built as a static part of the library. + +I build this branch on Ubuntu, with the system default +librados-dev package and its dependencies installed. I use +the autotools and the only thing I have to specify is the +linker flags: + +LDFLAGS="-L/path/to/librados -lrados" + +YMMV, but the autotools do no librados hunting so you may +need to specify things it can't figure out on its own. + +MOBJECT: + +You'll need to be able to find the headers and libs for +mobject-store. You do not need the RADOS libraries. + +On jelly (THG), this will work: + +export SPACK_ROOT=/mnt/hdf/jsoumagne/spack +source $SPACK_ROOT/share/spack/setup-env.sh +module load GCC +source <(spack module tcl loads --dependencies mobject) + +You will also need to define HDF5_USE_MOBJECT in CPPFLAGS. +This switches between the RADOS and mobject headers. + + +*********** +* TESTING * +*********** + +There are no tests for the RADOS VOL connector in the main +library, so running 'make check' won't provide much +information. + +RADOS: + +Once the library has been built, you can run some smoke +checks by running 'make install' and going to the +share/hdf5_examples/c/ directory and running the +run_rados_examples.sh script found there. That will +create a small pool (or clear it out if it exists) +and run all the example scripts in a sane order. + +*** YOU WILL NEED TO COPY YOUR ceph.conf FILE +*** INTO THIS DIRECTORY FIRST!!! + +In case it's not obvious, you'll need an active Ceph +cluster to run the tests :) + +MOBJECT: + +Same as above, only the script's name is run_mobject_examples.sh. + +You can probably ignore any sdskv_put warnings as long as the +examples pass. + +The tests are hard-coded to use /tmp/mobject-clust-test.gid and +this can be changed in h5rados_example.h. + +So to start mobject-server: + +mobject-server-daemon na+sm /tmp/mobject-cluster-test.gid |
