Accessing root grid file through xrootd failed on a dirac job when using singularity virtualisation. Now singularity is not expected to be found in $PATH on any dirac site had to use ganga pr #1670 to use singularity binary from cvmfs. However, i get an authentication failure when i try to access the root file with xrootd. Here's the simple shell script i'm running:

source /cvmfs/sft.cern.ch/lcg/views/LCG_95apython3/x86_64-centos7-gcc8-opt/setup.sh
python -c "import ROOT; ROOT.TFile.Open('root://gfe02.grid.hep.ph.ic.ac.uk/pnfs/hep.ph.ic.ac.uk/data/lz/lz/data/MDC3/calibration/LZAP-4.3.1/20180201/lz_20180201234_lzap.root').Get('Events')"

This is the ganga python job:

    j = ganga.Job()
    j.application=Executable(exe=File('worker_node_script.sh'), args=[])
    j.virtualization = Singularity("docker://luxzeplin/offline_hosted:centos7_2")
    j.virtualization.binary='/cvmfs/oasis.opensciencegrid.org/mis/singularity/current/bin/singularity'
    j.virtualization.mounts = {'/cvmfs':'/cvmfs', '/srv':'/srv'}
    j.backend = Dirac()
    j.submit()

This is the error message:

Error in <TNetXNGFile::Open>: [FATAL] Auth failed
Traceback (most recent call last):
  File "<string>", line 1, in <module>
ReferenceError: attempt to access a null-pointer

Here are the x509 envs for the dirac singularity:

printenv | grep SINGULARITY
SINGULARITY_APPNAME=
SINGULARITY_NAME=singularity_sandbox
SINGULARITY_CONTAINER=/tmp/25355128/singularity_sandbox
printenv | grep X509
X509_CERT_DIR=/etc/grid-security/certificates
X509_VOMS_DIR=/tmp/etc/grid-security/vomsdir
X509_USER_PROXY=/tmp/proxy

Within the container you can access X509_VOMS_DIR, X509_USER_PROXY but not X509_CERT_DIR.

When re-running and setting export XRD_LOGLEVEL="Debug" here is the log:

There are few different options for solving this. Either of the options below should work.

  • Explicitly mount in the /etc/grid-security/certificates directory to the container.
  • Export X509_CERT_DIR=/cvmfs/lhcb.cern.ch/etc/grid-security/certificates inside the container (or some other location in /cvmfs where the certificates are kept updated.

If the first options works, we can fix the wrapper such that you in the j.virtualization.mounts can put environment variables that are evaluated on the worker node.

I did both options and the job was successful in both cases. I was able to use xrootd in python to access the file on the grid. However the status of both jobs is failed. When i looked at the logging info the JobWrapper is on status Done with minor status is Execution Complete but JobAgent@CLOUD.UKI-LT2-IC-HEP-lz is on status Failed with minor status Singularity CE Error: Command failed with exit code 2 but when i look at the logs i don't see any errors.

@alexanderrichards Can you take a look at these jobs in the WMS interface at Imperial (or let me know the URL). I do not quite understand what is going on here.
@asnaylor Is the job reported as 'completed' or 'failed' in Ganga? I am not sure that you care about the Job Agent but I might misunderstand what you say here.

@asnaylor See now that you state job as failed. Do you understand what it is that gives the error code? Is it your script that has a non-zero error code (that singularity then propagate?).

I can now replicate this on CLOUD.UK-CAM-CUMULUS-backfill.uk. I wonder if it is caused by a Singularity container running inside another singularity container? As the job executes OK, it is related to the clean-up afterwards.

@alexanderrichards Can you take a look at these jobs in the WMS interface at Imperial (or let me know the URL). I do not quite understand what is going on here.

Do you still need me to do this if you understand the issue and have a fix? If so is there a specific job id to look for or just anything from @asnaylor

So it works at some sites but not other sites? I suspect that it is your mounting of /srv

j.virtualization.mounts = {'/cvmfs':'/cvmfs', '/srv':'/srv'}

(which is a bit of a hack) that doesn't work everywhere. Can you remember what it was that we tried to fix with that change?

At the moment i am mounting:

j.virtualization.mounts = {'/cvmfs':'/cvmfs', '/srv':'/srv', '/etc':'/etc', '/scratch':'/scratch'}

I was mounting /srv to allow the container access to X509_VOMS_DIR and X509_USER_PROXY.

is there a way to mount just those explicit folder to the container using the variables (X509_CERT_DIR, X509_VOMS_DIR and X509_USER_PROXY)?

I ran the same job on a couple of different dirac sites and collated the results. A lot of the jobs were successful but it seems like there is a two failure modes; the first is just mounting the correct X509 folders for the job and second is that Request lacks the org.dcache.uuid property.

I will try to implement a pre-ample to starting the Singularity container. This will allow for some python code to be executed beforehand. I think that is better than just allowing for environment variables in the mounts (which will fail for X509_USER_PROXY as it is a file and not a directory).

The issue of the org.dcache.uuid property, I still do not know what is going on there. It is obviously not related to the singularity container itself (then it would fail everywhere). can you try to do a printenv inside the job. We can then compare this for a working and non-working site and try to work out where there might be a difference.

I eventually got a reply from xrootd support, see xrootd/xrootd#1202 (comment)
So it seems like this is not a problem of Ganga or Singularity. Annoying. In any case I close the issue here.
