Categories of files/samples on _Disk:

  • files/samples without custodial location (we produced them but don’t want them to go to tape)
  • files/samples with custodial location, we decided to keep them on _Disk permanently
    • RAW of 2012 data for re-reconstruction passes
    • AOD of 2012 data for analysis
    • => the rules we used for populating the _Disk endpoint
  • input to workflows which are not in the other categories
    • can be cleaned up after we checked that the workflow is finished
    • start talking to the workflow team => why can’t the workflow team delete the input samples after they announced the output
    • there is also a web interface where you can see if a workflow is still running or not
  • output of workflows (AOD, AODSIM)
    • in general we would like output of recent workflows to stay on disk
    • old output can be considered to be cleaned up
* important that we check that there is a custodial location * we split in the above 3 categories * make lists for all samples split into era/tier


to have the T1_*_Disk endpoints filled below 80% of their capacity


  • check every week and if _Disk is > 80% full, make suggestion to clean up
  • check for samples that are on several _Disk endpoints

First to clean up:

* GEN-SIM which has already been processed and is not expected to be processed again

1- Get all GEN-SIM datasets at T1_UK_RAL_Disk*/*/GEN-SIM or

python --service blockreplicasummary --options "node=T1_UK_RAL_Disk&create_since=0" --path /phedex/block/name | tee cleaning_blocks

2- Exclude datasets without custodial location

cat cleaning_blocks | cut -d '#' -f 1 | sort | uniq > cleaning_datasets
awk '{system("python --option custodial:y --dataset "$1)}' cleaning_datasets

3- Exclude datasets if they are being used by a running workflow as an input ("assigned|acquired|running|running-open|running-closed|assignment-approved")

4- Exclude dataset if it is an output dataset of a workflow which finished within last ~6 months

5- Cross-check if remaining datasets have a custodial location

6- Send the list to Andrew( and Dave(

7- If they approve the list, create a deletion request.

Second to clean up:

data RAW: first 2011, then 2012
