Re: [HTCondor-users] Drained 0 machines

["Beyer, Christoph" <christoph.beyer@xxxxxxx>]

Hi,

look for DEFRAG_REQUIREMENTS & DEFRAG_WHOLE_MACHINE_EXPR

These knobs define the requirements which machines can be drained and what is considered a drained machine

for ex: 

# machine should be partiionable and online
DEFRAG_REQUIREMENTS = PartitionableSlot && Offline=!=True
# drain down to a blob of 12 online cores  
DEFRAG_WHOLE_MACHINE_EXPR = Cpus == 12 && Offline=!=True

Best

Betreff: [HTCondor-users] Drained 0 machines

Hello,
trying to configure Defrag on condor 8.8.9.
I need some help to understand this message in the DefragLog:

07/17/20 20:08:13 Looking for 15 machines to drain.
07/17/20 20:08:17 Drained 0 machines (wanted to drain 15 machines).

What is the condition used by Defrag to consider a machine available for 
draining?

Thanks for any hint,
Stefano
