Unable to View Any Archived Networks

Problem

You cannot view any existing archived networks on the Archives tab (Network > Browser > Archives) in the Paragon Planner desktop application GUI.

Solution

It is likely that the /opt/northstar/data directory has no space available or has less space available than is required to store an archived network.

1. Use your server credentials to log in to the primary node of Paragon Automation.

2. From the primary node, use the following command to check the capacity of the /opt/northstar/data directory:

   content_copy zoom_out_map

   root@primary-node:~# kubectl get pvc -n northstar

   Following is an example output that displays the capacity of the /opt/northstar/data directory:

   content_copy zoom_out_map

   NAME     STATUS   VOLUME                                     CAPACITY   ACCESS MODES   STORAGECLASS   AGE
   ns-data  Bound    pvc-f24d9e79-5bbe-4f12-ace3-aa4b3fd420b9   6Gi        RWX            rook-cephfs    48d
   

3. (Optional) From the primary node, use the following command to check the capacity and usage of the Ceph storage space:
   content_copy zoom_out_map

   root@primary-node:~# kubectl exec -ti -n rook-ceph $(kubectl get po -n rook-ceph -l app=rook-ceph-tools -o jsonpath={..metadata.name}) -- bash

   content_copy zoom_out_map

   [root@rook-ceph-tools-]# ceph status

   Following is an example output:

   content_copy zoom_out_map

   data: 
    volumes:  1/1 healthy
    pools:    11 pools, 177 pgs
    objects:  14.20k objects, 14GiB
    usage:    29GiB used, 71 GiB/100 GiB avail
    pgs:      14198/42594 objects degraded(33.333%)
              120 active+undersized+degraded
              57 active+undersized
   

   This information is useful to understand the amount of storage allocation that you can increase for the /opt/northstar/data directory.

4. Use the following command to obtain the name of the pod associated with the scheduler process (that is, the dcscheduler pod):

   content_copy zoom_out_map

   root@primary-node:~# kubectl get pod -n northstar|grep dcscheduler

5. Use the following command to log in to the dcscheduler pod:

   content_copy zoom_out_map

   root@primary-node:~# kubectl exec -it dc-scheduler-pod-name -c dcscheduler -n northstar -- bash

   In the command, dc-scheduler-pod-name is the name of the pod that you obtained in Step 4.

6. From the dcscheduler pod, use the following command to check the amount of free space available in the /opt/northstar/data directory:

   content_copy zoom_out_map

   root@dc-scheduler-pod-name:# df -h /opt/northstar/data

   Following is an example output:

   content_copy zoom_out_map

   Filesystem       Size  Used   Avail   Use%  Mounted on 
   Filesystem name  58G   14G    45G     24%   /opt/northstar/data
   

   If no free space is available in the directory, the Use% column in the output displays 0%.

7. If the percentage of space used is closer to the capacity of the directory, you can use one of the the following commands to make space in the directory:

   • To remove all directories created more than 24 hours ago (the recent directories might be in use):

     content_copy zoom_out_map

     root@dc-scheduler-pod-name:# ls -lrt

   • To remove a specific directory:

     content_copy zoom_out_map

     root@dc-scheduler-pod-name:# \rm -r directory-name

   You can now check whether you can view any archived networks in the GUI. If you still cannot view any archived networks, contact the Juniper Networks Technical Assistance Center (JTAC).
