835923 – OpenMPI problem with SELinux (Grid - parallel universe)

RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Daniel Horák 2012-06-27 14:40:56 UTC

Description of problem:
  OpenMPI job (parallel universe in MRG/Grid) fails because of Selinux problem.

Version-Release number of selected component (if applicable):
  # rpm -qa selinux-policy
    selinux-policy-3.7.19-155.el6_3.noarch
  # rpm -q condor
    condor-7.6.5-0.15.el6.x86_64
  
How reproducible:
  100%

Steps to Reproduce:
1. Install condor and OpenMPI and configure it for using parallel universe.
2. Prepare and submit OpenMPI job (see bug 537232 comment 2).
3. After job finish, check output files of the job and selinux messages:

# getenforce 
  Permissive

# START_DATE_TIME=$(date "+%m/%d/%Y %T")

<< submit job and wait for finish >>

Output file is empty and error file contain following error (First warning about plm_rsh_agent is related to bug 772587):
# cat /tmp/openmpi_errfile.9.0-0 
  --------------------------------------------------------------------------
  A deprecated MCA parameter value was specified in the environment or
  on the command line.  Deprecated MCA parameters should be avoided;
  they may disappear in future releases.

    Deprecated parameter: plm_rsh_agent
  --------------------------------------------------------------------------
  --------------------------------------------------------------------------
  A daemon (pid 29361) died unexpectedly with status 255 while attempting
  to launch so we are aborting.

  There may be more information reported by the environment (see above).

  This may be because the daemon was unable to find all the needed shared
  libraries on the remote node. You may set your LD_LIBRARY_PATH to have the
  location of the shared libraries on the remote nodes and this will
  automatically be forwarded to the remote nodes.
  --------------------------------------------------------------------------
  --------------------------------------------------------------------------
  mpirun noticed that the job aborted, but has no info as to the process
  that caused that situation.

Actual results:
  There is many avc errors and openmpi job fail.

Expected results:
  There is no avc error and openmpi job pass.

Additional info:
  This bug is probably connected with bug 759403.

  After additional investigation I found, that the problem appear somewhere between selinux-policy-3.7.19-150.el6 and selinux-policy-3.7.19-153.el6.

Comment 22 Daniel Horák 2012-12-07 15:38:45 UTC

Tested via automatic test on RHEL 6.4 i386/x86_64 on two versions of condor
  condor-7.6.5-0.22.el6.i686
  condor-7.8.7-0.6.el6_3.i686

# cat /etc/redhat-release 
  Red Hat Enterprise Linux Server release 6.4 Beta (Santiago)

# rpm -q selinux-policy
  selinux-policy-3.7.19-185.el6.noarch

No selinux problem found, proposing to VERIFIED.
