To be precise, it removes all files in /. Hopefully nobody runs mpirun as root... We had literally just found this same code path. Looking into it... Ticket filed upstream: https://svn.open-mpi.org/trac/ompi/ticket/4534 |
Created attachment 887244 [details] Strace of mpirun, showing the unlink commands on / Description of problem: mpirun contains a bug which causes it to remove all symlinks in / if it is run as root. This renders the system unusable. Version-Release number of selected component (if applicable): 1.8-1 How reproducible: always Steps to Reproduce: 1.module load mpi/openmpi-x86_64 2.mpirun -np 12 -hostfile hosts.openmpi foo 3. Actual results: all shell commands fail because their executables refer to /lib64 Expected results: mpirun either runs the command or reports an error. Additional info: When you test this, it might be useful to have this script running in a different window first: #!/usr/bin/python import os raw_input('Press enter after running mpirun and confirming damage to /') os.symlink('/usr/bin','/bin') os.symlink('/usr/lib','/lib') os.symlink('/usr/lib64','/lib64') os.symlink('/usr/sbin', '/sbin')
