Task is stuck at 99% on the UI

nexus

To cancel or manage a stuck task in the nSSV user interface (UI), you can follow several procedures, from standard cancellation via the console to a forced restart of the management services.

Cancellation via the Web Interface (Standard Method)
The nSSV platform allows you to manage ongoing tasks directly from the control panel:
Path: Navigate to O&M Management (or Platform O&M) > Tasks (or Operation Log) > Current Task
Action: Locate the stuck task in the list, click the Actions button, and select Cancel
Note: This section also allows you to pause (suspend) or resume (resume) ongoing operational tasks.
Troubleshooting Tasks Stuck at 99%
If a task (such as deleting a snapshot or migrating) remains stuck at 99.99% for an excessive amount of time:
Log Analysis: You can use the task’s Action ID to analyze the management node logs and verify whether the operation is actually stalled or processing a large amount of data.
virsh Verification: For disk or snapshot operations, you can verify the actual status on the compute node using the virsh domblklist command to see if the files have actually been consolidated.
Forced Delete via CLI (If the UI is Frozen)
If the task queue on the Management Node is completely frozen and unresponsive to UI commands, sources suggest using the CLI on the Management Server:
Service Restart: To unblock the message queue and forcefully stop pending processes, restart the Management Service with the command: cloud-ctl restart_node
Full Reboot: If necessary, you can stop and restart all services (including the UI) with: cloud-ctl stop && cloud-ctl start

Process Intervention: In extreme cases of a complete freeze, it may be necessary to manually kill any orphaned or frozen processes indicated in the system logs before restarting the MN service.

Warning: Restarting the management service (cloud-ctl restart_node) does NOT stop running virtual machines, but it temporarily makes the management interface unavailable and may cause tasks that were running correctly to fail.
