Description
We have a confirmed case of over softquota causing file corruptions. We had other reports in the past but couldn't confirm until now. The test job writes 418 hdf4 file and about 10-15 will be corrupted. We confirmed this using 2 different filesystem. The files are single striped and are written from a single mpi rank.
In the attached debug file one of the corrupted files was written to nocache-OST0047 at 1459304302
Also attaching strace of the corrupted file IO.
