  • Cinder with NetApp ONTAP Block/iSCSI/NFS backend
  • Glance multistore using NetApp NFS backend

Issue

When launching a VM from a newly uploaded image (not previously cached) in OpenStack, the instance creation fails with an error similar to:

Error: failed to perform the requested operation on instance, The instance has an error status. Please try again later... Volume <id> did not finish being created even after we waited for 187 seconds or 61 attempts, and its status is creating.

In the Cinder volume logs, the following is observed:

No accessible image volume for image <image_id> found.
...
Downloaded image <image_id> to volume <volume_id> successfully.
...
The NetAppCmodeISCSIDriver volume driver's get_volume_stats operation ran for 232.3 seconds. This may indicate a performance problem with the backend which can lead to instability.

  • The first VM creation from a new image fails or takes excessive time (often exceeding default Nova/Cinder timeouts).
  • Subsequent VM/volume creations from the same image succeed quickly after the image cache is created in the Cinder backend.
