How to use the cta-change-storage-class

The cta-change-storage-class can be used to change the storaegclass of files. To storage class update of the eos containers must be done manually by an operator.

cta-change-storage-class --id/-I <archiveFileID> | --json/-j <path> --storageclassname/-n <storageClassName> [--frequenzy/-t <eosRequestFrequency>]

where the json file is a text file with one json object for each line, example:

{"archiveId": <archiveId>}
{"archiveId": <archiveId>}
{"archiveId": <archiveId>}

The tool must be run from the frontend as it needs access to both eos and the catalogue. This means that and cta-cli.conf and a eos.grpc.keytab must be copied to the frontend. cta-cli should be placed in /etc/cta, while the location of eos.grpc.keytab should be specified in cta-frontend-xrootd.conf. If the tool fails to update any of the files, the ids can be found in /tmp/skippedArchiveIds.txt in json format.
