Re: [HTCondor-users] /dev/shm bug fix mentioned in release notes of 8.9.7

[ervikrant06@xxxxxxxxx]

Thanks Greg. It worked running container with privilegeÂmode showing expected behavior with 8.9.7 (/dev/shm/ getting cleared after job completion) however in 8.9.6 (/dev/shm/ contains stale file after job completion also).Â

Thanks & Regards,

Vikrant Aggarwal

Vikrant:

I'm glad you enjoyed our online HTCondor week, and that you find the
minicondor docker image useful. In order to clear /dev/shm, HTCondor
needs not just root, but certain kernel privileges that aren't enabled
by default inside a docker container. I think this should work if you
start the docker container with privilege, e.g. docker run --privileged ...
