Discussion

There were some reports of user jobs failing in OSPool backfill containers due to insufficient storage space in /tmp. OSPool jobs almost always run inside Singularity containers and GlideinWMS has mechanisms that will decide what to mount from the host (in this case the backfill container), into /tmp inside the Singularity container:

• https://github.com/glideinWMS/glideinwms/blob/fa3babd2452c7deeb2b8de543595aa2412ddef7b/creation/web_base/glidein_startup.sh#L591
• https://github.com/glideinWMS/glideinwms/blob/fa3babd2452c7deeb2b8de543595aa2412ddef7b/creation/web_base/singularity_lib.sh#L1639

It'd be worth checking to verify that the affected user jobs were running inside Singularity.
