HDF5 v1.10 or above on the Lustre FS

If you unable to read the files on the lustrefs with the  HDF5 library v1.10 and above you should mount the FS with localflock option. The reason is flock support absence by default.

h5ls --version
h5ls: Version 1.10.1
h5ls snapshot.hdf5 snapshot_063.hdf5: unable to open file

mount -tlustrefs  -o localflock /lustre

Now everything is ok!!
h5ls snapshot.hdf5
