[HTCondor-users] Singularity and HTCondor on CentoOS 7 - "Home directory is not owned by calling user: /srv"

[Luke Kreczko <L.Kreczko@xxxxxxxxxxxxx>]

Dear all,

I am currently trying to configure Singularity (2.4.2) and HTCondor (8.6.10) on a CentOS7 WN (7.4, kernel 3.10.0-693.21.1).

I've followed the instructions in

http://opensciencegrid.github.io/docs/worker-node/install-singularity/#unprivileged-singularity

https://research.cs.wisc.edu/htcondor/manual/latest/3_17Singularity_Support.html

and rebooted the machine.

For testing I run everything in the  "/cvmfs/cernvm-prod.cern.ch/cvm3" image.

I can execute all examples on the node as both root and local user, HTCondor jobs work under native CentOS7, but enabling singularity leads to

ERROR  : Home directory is not owned by calling user: /srv
ABORT  : Retval = 255


I assume that singularity is started by the condor user but /srv is owned by the submitting user (?).

Has anyone seen this before and does know the solution?


Cheers,

Luke
