Solution :-
You can run the script “lcm_catalog_cleanup”. There is no downtime required to run the script
Need to have internet connectivity for port 80 and 443.
if port 80 is not open you can download to your local PC “lcm_catolog_cleanup“
Copy the content of the script and paste in any CVM bin directory.
Ex. nutanix@NTNX-PROD-CVM:~/cluster/bin$vi catalog_leader_printer
nutanix@NTNX-PROD-CVM:~/cluster/bin$ ./catalog_leader_printer
Catalog leader is at X.X.X.87
With internet connectivity
First we need to find the catlog leader using the “catalog_leader_printer” batch Script.
nutanix@NTNX-PROD-CVM:~ cd /home/nutanix/cluster/bin/
nutanix@cvm:~/cluster/bin$ wget http://download.nutanix.com/kbattachments/8027/catalog_leader_printer
nutanix@cvm:~/cluster/bin$ chmod +x catalog_leader_printer
nutanix@cvm:~/cluster/bin$ ./catalog_leader_printer
nutanix@NTNX-PROD-CVM:~/cluster/bin$ ./catalog_leader_printer
Catalog leader is at X.X.X.87
if the LCM framework version is greter than 2.3.3
nutanix@NTNX-PROD-CVM:~cd /home/nutanix/cluster/bin/lcm
nutanix@NTNX-PROD-CVM~/cluster/bin/lcm$python lcm_catalog_cleanup
Found master manifest, attempting to delete it.
Found product meta, attempting to delete it.
All items deleted successfully
and run the inventory again you will see the progress .
If with above method issue is not resolved then you can check with your internet connectivity.
nutanix@NTNX-PROD-CVM/cluster/bin/lcm$ curl http://download.nutanix.com/lcm/2.0/master_manifest.tgz -O
