Title:
Extend attached volume case failed
Status in Cinder:
New
Status in OpenStack Compute (nova):
New
Bug description:
The online expansion volume use case failed,
tempest.api.volume.test_volumes_extend:VolumesExtendAttachedTest.test_extend_attached_volume.
This use case was originally successfully executed and failed after
reinstalling devstack (stein-->train). The cinder driver has not
changed, and the multipath.conf configuration has not changed. There
are two kinds of errors in [email protected], one is the error
under the ubuntu18 system, and the other is the error under the
centos7 system. as follows
