Castor Diskpool, Unstaging Files

When the castor diskpool is getting full, one needs to unstage files from it.
Clone the ILCDiracOps git repository and run the script
StagerScripts/UnstageProdFiles -P'prodID' -F'REC|SIM'
prodID is the first production to check, REC|SIM the file types to unstage.

Production Output Data Checking

Sometimes something goes wrong and files that should not exist do exist. Jobs can fail, but their outputfiles are still picked up before they are removed. Jobs are rescheduled for no good reason, the jobs fail between uploading outputdata and creating removal requests...

Here are some scripts to deal with these outputfiles, these are also in the ILCDiracOps repository:

Check if Successful jobs have used the same input data for a given production:
CheckProdJobs -P'ProdID'

Check if the output from failed jobs still exists:
CheckFailedJobsFourOutputData -P'ProdID'

Check if there are production files wihtout ancestors:
CheckProductionAncestry -p'prodID' -t'filetype'

Also use the dirac-transformation-cli command to check and change files for productions.
