The ``cinder-manage db online_data_migrations`` command now returns exit
|
|
status 2 in the case where some migrations failed (raised exceptions) and
|
|
no others were completed successfully from the last batch attempted. This
|
|
should be considered a fatal condition that requires intervention. Exit
|
|
status 1 will be returned in the case where the ``--max-count`` option was
|
|
used and some migrations failed but others succeeded (updated at least one
|
|
row), because more work may remain for the non-failing migrations, and
|
|
their completion may be a dependency for the failing ones. The command
|
|
should be reiterated while it returns exit status 1, and considered
|
|
completed successfully only when it returns exit status 0.
