Is this a BUG REPORT or FEATURE REQUEST?:

Uncomment only one, leave it on its own line:

/kind bug /kind feature

What happened:

reported this before and can't find it now, so re-report and see whether we can improve

following the resize guide and the volume changed from 1G to 2G

# kubectl get pvc
NAME                    STATUS   VOLUME                                     CAPACITY   ACCESS MODES   STORAGECLASS          AGE

and logs shows

resize ok, but the size is still actually 1G

# kubectl exec nginx1 -- df -h /var/lib/www/html

/dev/vdf        976M  2.6M  958M   1% /var/lib/www/html

I don't have admin cred for this openstack so don't know why failed to extend (maybe policy ? ) but anyway better to detect this and report to upper layer... What you expected to happen:

How to reproduce it:

Anything else we need to know?:

Environment:

• openstack-cloud-controller-manager(or other related binary) version:
• OpenStack version:
• Others:

@jichenjc Can we close this? with recent change, the failure is reported well before right?

[jichenjc]

yes, I think at least we prevent that happen
