+# -----------------------------------------------------
+
+    How do I add and remove users from the live systems without having to do a redeploy?
+
+        https://github.com/wfau/gaia-dmp/blob/master/notes/zrq/20230704-01-new-users.txt
+        https://github.com/wfau/gaia-dmp/blob/master/notes/stv/20240228-new-user.txt
+
+    How do I backup user data and notebooks?
+
+        Backup notebooks live->data and live->offsite

+        https://github.com/wfau/gaia-dmp/blob/master/notes/zrq/20230517-01-backup-notebooks.txt
+
+        Backup notebooks live->offsite AND secrets data->offsite

+
+    Relatioship between data and the other projects ?
+
+        Data VM contains the SSL certificates from Let's Encrypt
+            Check with Stelios for details on these.
+
+        Data VM contains the secrets, including the DuckDNS token
+            Used to updated the IP address of colours, and live.
+
+        Data VM contains the passhashes
+            Used to populate the MariaDB database table for Zepelin accounts.
+
+        Data VM contains the backup of the notebooks
+            /var/local/backups/notebooks
+
+            New deploy will copy notebooks from data
+
+            It is up to us to pull a new backup from live->data manually.
+            We _could_ have a cron job on data that pulled backups.
+
+        Data project holds the home shares for live users
+        Data project holds the user shares for live users
+        Data project holds the science data shares
+
+        These are all mounted via kernel mount entries in /etc/fstab in each VM.

+            https://github.com/wfau/gaia-dmp/blob/master/deployments/hadoop-yarn/ansible/51-cephfs-mount.yml
+
+    How do I change the “live” gaia dns to point at green,blue,red respectively?
+
+        Use the DuckDNS token from secrets to update the live.

+        Need to make a support request to change dmp.gaia.ac.uk
+
+    Point me at a list of known issues or a troubleshooting guide.
+

+            cephfs mount fails
+            shares stuck in deleting
+            openstack is foobar
+
+
+    Discuss the best way to resolve the versions issue that’s preventing deploying the current main branch, as this will presumably be the first issue for me to resolve
+
+        Check with Stelios.
+
+    TODO
+
+    Go through a checklist that I’m on all the necessary mailing lists and have access to everything I should have access to.
+
+
+    Go through Resource request details
+        email in to with deniza
