Description Luigi Tamagnone 2021-05-24 16:47:53 UTC
Description of problem:
The instance creation fails with "Build of instance 8738645d-de56-4331-85e5-1decf756cd9c aborted: Unable to update the attachment. (HTTP 500)" The same volume on other compute nodes works.
This issue happens for every volume from VMAX backend
The issue could be bind with BUG 1942079. But I'm not sure.

Version-Release number of selected component (if applicable):
[redhat-release] Red Hat Enterprise Linux Server release 7.7 (Maipo)
[rhosp-release] Red Hat OpenStack Platform release 13.0.10 (Queens)

How reproducible:
The customer can reproduce the error every time they try to create an instance from a volume.

Steps to Reproduce:
1. create volume in VMAX backend from an image
2. Create an instance from that volume

Actual results:
Instance creation fails

Expected results:
instance creation succeed
