[HTCondor-users] How to handle a node where jobs are failing

[Martin Sajdl <masaj.xxx@xxxxxxxxx>]

Hi All,

I need a help with the following issue:
there was a PC/node newly connected to our pool which had high rank for 
many tasks (many of them was assigned to this node even the other was 
free as well), but the node was wrongly configured by mistake, so all 
the tasks was not able to run there... This combination caused that 
almost all the tasks were tried to be run on that node with no success 
again and again.
My question is. Is there a configuration option which enables to eg. 
disconnect a node from the pool when N subsequent job failed there or to 
set the pool to try to assign the task to a different node when it 
failed on the first one.
My idea is to decrease the rank of the node for the tasks - set a 
classad every time when a task fails and use this value in RANK 
formula... But maybe there is batter way I do not know about.

Thank you in advance!
