+* Mark a node as in maintenance mode  
+> ha-manager crm-command node-maintenance enable _node_
+* Bind mount for NAS
+> mp0: /mnt/pve/NAS,mp=/mount/nas-sp
+### Improvements in containers
+* UniData
+    * Move Error pages to Jenkins
+* Jenkins Agent
+    * delete mvn cache daily (confirm) (systemd.timer)
+* Upgrade containers to Debian 12Ignoring (git reset) changes that are not suposed to
+
+* Monitoring
+    * Dependencies
+        * sql:
+        * git
+        * jenikis
+        * icinga
+        * EBX Artifacts
+        * UDE files
+    * Add permanent VMs (jenkins, git, etc...)
+* Archiva
+    * Replace by something else
+
+# (DRAFT) Proxmox node removal procedure
+  * Remove node from pve_nodes table as SysDB
+  * Move the node to maintenance mode
+    > ha-manager crm-command node-maintenance enable node
+  * Wait for automated migrations to finished
+  * Manualy migrate any remaining container
+  * Destroy all replications pointing to the node  
+    __CAN BE AUTOMATED BY CheckConsitency PIPELINE?__  
+    May be as an option to destroy all replications before creating them again.
+    That way, all non needed replications will be destroyed.
+    This can be expensive as it will have to create all replicas again.  
+    If we move to Ceph, all this point bexomes moot.
+  * Remove the node from HA groups
+  * Double check there is nohing still attached to the node 
+  * Disable node in icinga
+  * Reinstall the node from the OVH control pannel  
+    To make sure the server never starts again with the current identity.
+    That will generate problems.
+  * _pvecm nodes_
+      * Confirm that node is not anymore in the list
+  * _pvecm delnode XXX_
+      * Is normal to get an error because can't reach the node
+
