[HTCondor-users] Is our Defrag working?

[Jeff Templon <templon@xxxxxxxxx>]

Hi,

Our defrag daemon seems to be in a funny state of working and also not working.  In any case, the logging seems like it cannot be correct, as it says that it is draining and also not draining.

Exhibit 1: the defrag log never says itâs draining:

$ grep urrently DefragLog | cut -d" " -f3-8 | sort -n | uniq -c

      5 Couldn't fetch startd ads using constraint

   1149 There are currently 0 draining and

      5 There are currently -1 draining and

Exhibit 2 : the DefragLog regularly says itâs draining:

$ grep nitiating DefragLog | cut -d" " -f3-8 | sort -n | uniq -c | sort -nr

     65 Initiating graceful draining of slot1@xxxxxxxxxxxxxxxxxxxxxx

      7 Initiating graceful draining of slot1@xxxxxxxxxxxxxxxxxxxxx

      4 Initiating graceful draining of slot1@xxxxxxxxxxxxxxxxxxxxxx

      3 Initiating graceful draining of slot1@xxxxxxxxxxxxxxxxxxxxxx

      3 Initiating graceful draining of slot1@xxxxxxxxxxxxxxxxxxxxxx

Exhibit 3 : the DefragLog says itâs both draining and not draining:

07/05/24 12:00:54 Initiating graceful draining of slot1@xxxxxxxxxxxxxxxxxxxxxx

07/05/24 12:00:54 Expected draining completion time is 580s; expected draining badput is 4786 cpu-seconds

07/05/24 12:00:54 Drained maximum number of machines allowed in this cycle (1).

07/05/24 12:00:54 Drained 1 machines (wanted to drain 1 machines).

07/05/24 12:05:55 There are currently 0 draining and 1 whole machines.

07/05/24 12:05:55 Set of current whole machines is

07/05/24 12:05:55        wn-sate-079.nikhef.nl

07/05/24 12:05:55 Set of current draining machines is

07/05/24 12:05:55 (no machines)

07/05/24 12:05:55 Newly Arrived whole machines is

07/05/24 12:05:55 (no machines)

07/05/24 12:05:55 Newly departed draining machines is

07/05/24 12:05:55 (no machines)

If it had just drained the machine, how did that not even take one second?  And why is it then not listed under the whole machines?
