Re: [HTCondor-users] sandbox too small

[Cole Bollig <cabollig@xxxxxxxx>]

Hi Christoph,

No, as the following line states file transfer was successful. Traditionally when the shadow and starter are ready to begin transferring files (input or output) the shadow enters the schedd's transfer queue. This queue is to do a user fair share ordering of file transfers for jobs, so the AP doesn't get bogged down due to many active file transfers at once. The drawback to this queueing of transfers is jobs with very little/minimal bytes of data to transfer may get stuck waiting in the queue to transfer, so we added functionality so that jobs with a sandbox to transfer under a specified size bypass the transfer queue and just begin transferring data. This default value is 100MB. This can be overridden by the currently undocumented configuration knob BYTES_REQUIRED_TO_QUEUE_FOR_TRANSFER.

Hope this helps,

Cole Bollig

Hi,

I see a lot of these in the logs lately:


11/13/24 19:43:57 Initializing a VANILLA shadow for job 6276104.24
11/13/24 19:43:57 (6276104.24) (763436): LIMIT_DIRECTORY_ACCESS = <unset>
11/13/24 19:43:57 (6276104.24) (763436): Request to run on slot2_1@xxxxxxxxxxxxxxxxx <131.169.165.129:37923?addrs=131.169.165.129-37923+[2001-638-700-10a0--1-581]-37923&alias=batch1451.desy.de> was ACCEPTED
11/13/24 19:43:57 (6276104.24) (763436): Not entering transfer queue because sandbox (39229) is too small (<= 104857600).
11/13/24 19:43:58 (6276104.24) (763436): File transfer completed successfully.

Does that mean the input file transfer failed ?

best
