The 15.0.1 Ocata release contains fixes for several high severity, high
|
||||
impact bugs. If you have not yet upgraded to 15.0.0, it is recommended to
|
||||
upgrade directly to 15.0.1.
|
||||
issues:
|
||||
- |
|
||||
There is a known regression in Ocata reported in `bug 1671648`_ where
|
||||
server build failures on a compute node are not retried on another compute
|
||||
node. The fix for this bug is being worked and will be provided shortly in
|
||||
a 15.0.2 release.

|
||||
critical:
|
||||
- |
|
||||
`Bug 1670627`_ is fixed. This bug led to potential over-quota errors after
|
||||
several failed server build attempts, resulting in quota usage to reach the
|
||||
limit even though the servers were deleted.
|
||||
|
||||
Unfortunately the ``nova-manage project quota_usage_refresh`` command will
|
||||
not reset the usages to fix this problem once encountered.
|
||||
|
||||
If the project should not have any outstanding resource usage, then one
|
||||
possible workaround is to delete the existing quota usage for the project::
|
||||
|
||||
``nova quota-delete --tenant <tenant_id>``
|
||||
|
||||
That will cleanup the ``project_user_quotas``, ``quota_usages`` and
|
||||
``reservations`` tables for the given project in the ``nova`` database and
|
||||
reset the quota limits for the project back to the defaults defined in
|
||||
nova.conf.

fixes:
|
||||
- |
|
||||
`Bug 1665263`_ is fixed. This was a regression where
|
||||
``instance.delete.start`` and ``instance.delete.end`` notifications were
|
||||
not emitted when deleting an instance in ``ERROR`` state due to a failed
|
||||
build.
