Environment

• Platform9 Managed OpenStack - All versions.

• Cinder

Cause

The Cinder Volume shows migration status as "migrating" even after completion of migration.

Resolution

1. Check if the volume is successfully migrated to the destination Cinder node. Also check for any errors in cinder logs of source/destination nodes and on the management plane.

2. If the volume is successfully migrated run the below command to reset the status

command

# cinder reset-state --reset-migration-status <volume-uuid>
