Hi all, I see occasional problems for jobs started into Singularity containers that the target bind-mount of the job's scratch dir is not writable . Nominally, I am mounting scratch onto /srv in the container, where /srv is existing as directory in the container (or is the target dir supposed to be not existing in the container? Overlay is enabled for Singularity). Cheers, Thomas  ESC[33mWARNING: Could not create mount point directory in container /var/singularity/mnt/final/var/home/desyusr003: Operation not supported ESC[0mESC[33mWARNING: Not mounting /tmp (already mounted in container) ESC[0mESC[33mWARNING: Not mounting /var/tmp (already mounted in container) ESC[0mmkdir: cannot create directory `/mR6MDmgpudtn31DnJpCqFYppBe2THoABFKDmQwfKDmABFKDmzPU8Xm': Permission denied mv: cannot move `././stest.sh' to `mR6MDmgpudtn31DnJpCqFYppBe2THoABFKDmQwfKDmABFKDmzPU8Xm/.': No such file or directory /srv//condor_exec.exe: line 89: /mR6MDmgpudtn31DnJpCqFYppBe2THoABFKDmQwfKDmABFKDmzPU8Xm.diag: Permission denied /srv//condor_exec.exe: line 94: cd: /mR6MDmgpudtn31DnJpCqFYppBe2THoABFKDmQwfKDmABFKDmzPU8Xm: No such file or directory Failed to switch to '/mR6MDmgpudtn31DnJpCqFYppBe2THoABFKDmQwfKDmABFKDmzPU8Xm' btw: in the root namespace /home is a bind-mount to /var/home, where pool accounts live.
