5 Essential Tips for Maximizing Your Experience at Nutanix .NEXT for Bloggers
As an update - no further with fixing the LCM - still issues with updating LCM.The cluster seems to be running with ok health(recently recovered from failed state due to hosting issues) Prism reports slightly different error now:Operation failed. Reason: Prechecks failed: Found remote version None while 2.5.0.3.33256 was expected on node 10.15.17.239. This may be a caching issue. Please ensure all local caches are cleared and wait a few minutes for any remote caches to get invalidated before retrying. Please check KB 7784This seems related to the LCM version mismatch between nodes found in cvm commands.I think it might be an idea to remove the node from the cluster completely and re-add - from what i can tell i think i need 4 nodes to do this operation via this process https://portal.nutanix.com/page/documents/details?targetId=Web-Console-Guide-Prism-v6_5:wc-removing-node-pc-c.html
Support asked if i could remove the commands for 'ergon_update_task' from my post.I dont think i can do this(i cant edit anything) - im leaving a note for others that you shouldnt do this without direct interaction with Nutanix Support.I think they want to avoid user's doing this as a normal operation or troubleshooting process.
Update. I created the missing file using zkcli cat /appliance/logical/lcm/mercury_config/050e9777-d7b3-4957a0-3f6a060611acI then rebooted every node sequencially using maintenance mode and cliNo change in lcm or reboot processes stuckTried genesis restart command - no effectI then ranergon_update_task --task_uuid='XXXXXXXXXXXX' --task_status=succeeded or (aborted)aganst the affected tasks - now tasks are clear, but still LCM framework page is stuck with message:‘ LCM Framework Update in Progress, please check back when the update process is completed. ‘‘ Error calling Entities : Error: Not Found ‘I then ran another set of restarts on nodes The 2 nodes with lcm framework up to date have this output for their uuidsnutanix@NTNX-e0c1425c-A-CVM:X.Y.Z.237:~/data/logs$ allssh zkcli cat /appliance/logical/lcm/mercury_config/d4c6a6b9-ad84-429f-8ac7-d4b671e5c1e7================== X.Y.Z.238 =================1.3================== X.Y.Z.239 =================1.3================== X.Y.Z.237 =========
Also does anyone know if runing ‘genesis restart ‘ on the current leader will cause issues with workload? I presume i may need to do this to trigger the leader to switch. If there is any doubt i can do a manual node restart from cli.

Thanks for the reply - thats exactly one of the previous discussions i was looking at to help fix this. Not many the same issue i think but similar.Do you know what might be missing the uuid? a config file used by a service or some other field or list?I'm not clear on the logs exactly what component it is ‘Unable to find node_uuid for **node3** ‘I'll see about ending the tasks – may take some time to organize to make sure interested parties are all ok with my changes.
