Rucio
Rucio web requests are handled via https://cms-rucio-webui.cern.ch/r2d2/request
If you want to make a request (rule in rucio), follow the following tuturial.
This are basic instructions on rucio.

- You need to be on sl7 for the commands to work
- initialise the env:
source /cvmfs/cms.cern.ch/cmsset_default.sh source /cvmfs/cms.cern.ch/rucio/setup-py3.sh voms-proxy-init -voms cms -rfc -valid 192:00 export RUCIO_ACCOUNT=`whoami`
- in rucio, a transfer is called a rule. In order to create a rule:
rucio add-rule cms:/CMS/DATA/SET/NAME 1 T2_MY_SITE rucio add-rule cms:/CMS/DATA/SET/NAME#BLOCK-NAME 1 T2_MY_SITE
- if there is a lot of data, add
--asynchronous
- users can also request rules, who are then to be approved by the admins. This is done with 2 extra modifiers:
--ask-approval
and
--lifetime (in seconds; for reference, 30 days is 2592000 seconds)
- check your rules:
rucio list-rules --account $RUCIO_ACCOUNT List all the rules you have and their state rucio rule-info [RULE_HASH] monitor the progress of your rule and any transfers it may have initiated
Example:
rucio list-rules --account $RUCIO_ACCOUNT ID ACCOUNT SCOPE:NAME STATE[OK/REPL/STUCK] RSE_EXPRESSION COPIES EXPIRES (UTC) CREATED (UTC) -------------------------------- --------- ------------------------------------------------------------------------------------------------------------------------------------------------ ---------------------- ---------------- -------- ------------------- ------------------- eafda759f4ae4128b49fede980db5622 odevroed cms:/Neutrino_E-10_gun/RunIISummer17PrePremix-PUAutumn18_102X_upgrade2018_realistic_v15-v1/GEN-SIM-DIGI-RAW#0149acf0-6b06-43c9-b99f-dfc531b6eecb OK[235/0/0] T2_BE_IIHE 1 2021-02-19 15:11:47 2021-01-20 15:11:47 rucio rule-info eafda759f4ae4128b49fede980db5622 Id: eafda759f4ae4128b49fede980db5622 Account: odevroed Scope: cms Name: /Neutrino_E-10_gun/RunIISummer17PrePremix-PUAutumn18_102X_upgrade2018_realistic_v15-v1/GEN-SIM-DIGI-RAW#0149acf0-6b06-43c9-b99f-dfc531b6eecb RSE Expression: T2_BE_IIHE Copies: 1 State: OK Locks OK/REPLICATING/STUCK: 235/0/0 Grouping: DATASET Expires at: 2021-02-19 15:11:47 Locked: False Weight: None Created at: 2021-01-20 15:11:47 Updated at: 2021-01-20 15:36:07 Error: None Subscription Id: None Source replica expression: None Activity: User Subscriptions Comment: None Ignore Quota: True Ignore Availability: False Purge replicas: False Notification: NO End of life: None Child Rule Id: None

- requests can also be done for users, but I have not tested this.
- users can also be given quota’s
- datasets can be grouped into containers. This can be handy if several datasets are needed for a specific analysis. All of then can then also be removed together if the analysis is finished. This is done via rucio containers. More info here.
