I recently used LCM to update the firmware on my 9 node cluster. One of the hosts did not come back up. I was able to get it to reboot back into the host OS, but it had no network connectivity. The interfaces were up, IP address assigned, just no traffic passing through the bridge.

 

After fighting with it for some time, I decided to eject the node from the cluster and just re-foundation a new one. I initiated the removal process, but the node status remains in MARKED_FOR_REMOVAL_BUT_NOT_DETACHABLE:

nutanix@NTNX-<REDACTED>-A-CVM:10.1.153.30:~$ ncli host ls id=21

    Id                        : 0005adca-5f30-1bf1-0000-000000008d15::21

    Hypervisor Address        : 10.1.153.15
    Host Status               : MARKED_FOR_REMOVAL_BUT_NOT_DETACHABLE

    Under Maintenance Mode    : false (life_cycle_management)
    Metadata store status     : Node is removed from metadata store
    Node Position             : Node physical position can't be displayed for this model. Please refer to Prism UI for this information.
    Node Serial (UUID)        : <REDACTED>
    Block Serial (Model)      : 0123456789 (NX-8035-G4)

 

I followed this (
https://support-portal.nutanix.com/page/documents/kbs/details?targetId=kA00e0000009D6CCAU) article, but after confirming that the node status was indeed still in MARKED_FOR_REMOVAL_BUT_NOT_DETACHABLE, and that the host was removed from the metadata ring:

It has been sitting in this state for over a week now. I also tried manually removing the node using:

ncli host remove-start id=21 skip-space-check=True

 

It reports that the node removal was successfully initiated, but I see no change in operation.

 

Any help is greatly appreciated.
