This directory contains scripts to be executed by the EOS workflow engine.
These scripts should be installed in the following directory on the EOS
mgm node:
/var/eos/wfe/bash/
For example the following script is executed when a tape server triggers
an archived.default workflow event:
/var/eos/wfe/bash/create_tape_drop_disk_replicas
The following "eos attr set" commands can be used to build the workflow
actions of an EOSi/CTA instance. Please remember to replace
CTA_WF_DIR with the path specific to you're EOS instance, for example
/eos/dev/proc/cta/workflow. Please also replace CTA_BIN with the full
path of the cta command-line tool.
EXECUTED WHEN AN END USER CLOSES A FILE THEY ARE WRITING TO EOS DISK
eos attr set sys.workflow.closew.default="bash:shell:cta XrdSecPROTOCOL=sss XrdSecSSSKT=${CTA_KT} ${CTA_BIN} archive --user <eos::wfe::rusername> --group <eos::wfe::rgroupname> --diskid <eos::wfe::fid> --instance eoscta --srcurl <eos::wfe::turl> --size <eos::wfe::size> --checksumtype <eos::wfe::checksumtype> --checksumvalue <eos::wfe::checksum> --storageclass <eos::wfe::cxattr:CTA_StorageClass> --diskfilepath <eos::wfe::path> --diskfileowner <eos::wfe::username> --diskfilegroup <eos::wfe::groupname> --recoveryblob:base64 <eos::wfe::base64:metadata> --reportURL 'eosQuery://${EOS_MGM_HOST}//eos/wfe/passwd?mgm.pcmd=event\&mgm.fid=<eos::wfe::fxid>\&mgm.logid=cta\&mgm.event=archived\&mgm.workflow=default\&mgm.path=/eos/wfe/passwd\&mgm.ruid=0\&mgm.rgid=0' --stderr" ${CTA_WF_DIR}
EXECUTED WHEN A TAPE SERVER REPORTS TO EOS THAT A FILE IS SAFELY STORED ON TAPE
eos attr set sys.workflow.archived.default="bash:create_tape_drop_disk_replicas:cta <eos::wfe::path> <eos::wfe::cxattr:CTA_TapeFsId>" ${CTA_WF_DIR}
EXECUTED WHEN AN END USER ON THE MGM NODE RUNS THE "xrdfs prepare" COMMAND

EXECUTED WHEN A TAPE SERVER CLOSES A FILE IT IS RETRIEVING TO DISK
eos attr set sys.workflow.closew.CTA_retrieve="bash:shell:cta eos attr set 'CTA_retrieved_timestamp=\"\`date\`\"' <eos::wfe::path>" ${CTA_WF_DIR}
EXECUTED WHEN AN END USER RUNS THE "eos rm" COMMAND

Changing /etc/ctafrontend_SSS_c.keytab and /etc/ctafrontend_SSS_s.keytab to /etc/cta/cta-cli.sss.keytab so that CI and preprod have now the same configuration files. Keep in mind thatL The user in the ctafrontend SSS key is the EOS instance name, the rest is BS. I tried to make it clear in the configuration files and names when a field is useless. WFE scripts are now the same between preprod and CI and the ctafrontend configuration file can move in the rpm.
