===== Procedure for SE decommissioning ===== | ===== Procedure for SE decommissioning ===== | ||
- | * Submit a GGUS [[biomed-shifts:practices#during_ticket_submission|team ticket]] and assign it to VOSupport. | + | * SE decommissioning should be announced by site admins through a ticket assigned to Biomed VO support. It should clearly state the expected decommissioning date. |
- | * The expected decommissioning date should clearly appear in the ticket. | + | * Actions on VO admins: send a mail to biomed-users@googlegroups.com |
- | * Notify the concerned site of this ticket (field "Notify site"): this field only appears on existing team tickets, not on the team ticket creation form. So you have to first submit the ticket, then modify the "Notify Site" field. | + | |
- | * Ask the site admin to forbid lcg-cr writes from now on, using the email template below. To find the email address of the site administrator, do as follow: | + | |
- | * On the [[https://goc.egi.eu/portal/index.php|GOCDB]], search for the SE hostname (search box). | + | |
- | * In the results table, click the View link in the Action column; | + | |
- | * Then click on the site name (Parent Site information)). | + | |
- | * The admin email is provided in the contact table. | + | |
- | * **while (decomisioning deadline is not passed)** | + | |
- | * Get the list of LFNs and DNs having SURLs stored on this SE using [[Biomed-Shifts:LFCBrowseSE | LFCBrowseSE]]: ''LFCBrowseSE se-hostname.domain --vo biomed --lfn --dn --size --summary'' | + | |
- | * Put a link or attach this list in the ticket | + | |
- | * Notify the concerned users by email, and attach the list of files. | + | |
- | * **If** a user does not answer **or** doesn't need his/her files anymore **then** remove all the corresponding entries from the LFC (using lcg-ra <guid> <lfn>) | + | |
- | * **end while** | + | |
- | * Once the decommissioning date is passed and the decommissioning is confirmed by the site: | + | |
- | * make sure that the SE is no longer published in the BDII as supporting biomed, | + | |
- | * contact the Biomed SAM team (BIOMED-SAMBOX-L [at] in2p3 [dot] fr) that maintains the biomed Nagios box, and ask to remove the SE from the list of resources monitored by Nagios. | + | |
- | * Send the list of files of biomed users to the LFC administrator to remove the entries from the catalog: dbouvet [at] in2p3 [dot] fr | + | |

- | Dear biomed user,<br/> | + | |
- | <br/> | + | |
- | You have <font color="red">XXX</font> files on SE <font color="red">YYY</font> which will be decommissioned by <font color="red">X</font>.<br/> | + | |
- | <br/> | + | |
- | We have to move these files away or remove all the corresponding entries from the LFC (using lcg-ra <guid> <lfn>) in case you no longer need the data. Please don't hesitate to contact us (biomed-technical-support [[AT]] googlegroups [[DOT]] com) in case you have any questions or if you experience difficulties in this process.<br/> | + | |
- | <br/> | + | |
- | The list of the corresponding files is attached/available <font color="red">HERE</font><br/> | + | |
- | <br/> | + | |
- | Also, note that it is <b>not</b> recommended to try to move many files in parallel: due to scalability issues of the SE, only a limited number of concurrent connections can be initiated. | + | |
- | <br/> | + | |
- | <br/> | + | |
- | Thanks in advance,<br/> | + | |
- | The biomed technical team on shift<br/> | + | |

- | ===== Email template for site administrator ===== | + | <callout> |
+ | Dear Biomed users, | ||
- | ** Don't forget to customize the <font color="red">red text</font>.** | + | we've received notice that the SE <text type="danger">SEName</text> (hosted by site <text type="siteName">SSS</text>), which is used by Biomed, will be decommissioned on <text type="danger">date</text>. |
- | //**Title**//: | + | This is tracked through the following ticket: |
- | ><font color="red">SE_hostname</font> decommissioning - forbid write access for biomed users | + | <text type="danger">GGUS link</text> |
+ | |||
+ | If you have files on this SE, please consider checking quickly whether they have replicas somewhere else, or whether you should get/replicate them to avoid any data loss. | ||
+ | |||
+ | You can find relevant LFNs using | ||
+ | dirac-dms-find-lfns --SE=[SE name] Path=/ | ||
+ | then | ||
+ | dirac-dms-replica-metadata fileContainingLFNs SE | ||
+ | should return available replicas of individual files. | ||
+ | |||
+ | Kind Regards | ||
