Hi Michael,

I suspect we are chasing an incorrect lead with respect to the job suspension; the fakeroot is being leaked to the mount namespace, not the HTCondor one (so the bug I thought of does not apply here).

However, if you add:

MOUNT_UNDER_SCRATCH=/tmp

it should make those warning/error messages go away.

Could you tell a little more on why bind-mounting /tmp will disable the warnings? From the documentation it is not obvious to me.

 

What are your SUSPEND-related attributes set to on that worker node?

% condor_config_val -dump |grep -i suspend

MAXSUSPENDTIME = 10 * $(MINUTE)

SUSPEND = $(UWCS_SUSPEND)

TESTINGMODE_SUSPEND = False

TESTINGMODE_WANT_SUSPEND = False

UWCS_PREEMPT = ( ((Activity == "Suspended") && ($(ActivityTimer) > $(MaxSuspendTime))) || (SUSPEND && (WANT_SUSPEND == False)) )

UWCS_SUSPEND = ( $(KeyboardBusy) || ( (CpuBusyTime > 2 * $(MINUTE)) && $(ActivationTimer) > 90 ) )

UWCS_WANT_SUSPEND = ( $(SmallJob) || $(KeyboardNotBusy) || $(IsVanilla) ) && ( $(SUSPEND) )

VM_SOFT_SUSPEND = True

WANT_SUSPEND = $(UWCS_WANT_SUSPEND)

 

This is a dedicated cluster node -- no keyboard.

Thanks,

Michael
