Welcome to the “nova_status” role documentation.
metadata:
description: "Performs a release-specific readiness check before restarting services\
\ with new code. This command expects to have complete configuration and access\
\ to databases and services within a cell. For example, this check may query the\
\ Nova API database and one or more cell databases. It may also make requests\
\ to other services such as the Placement REST API via the Keystone service catalog\n\
The nova-status upgrade check command has three standard return codes:\n0 -> All\
\ upgrade readiness checks passed successfully and there is nothing to do. 1 ->\
\ At least one check encountered an issue and requires further investigation.\n\
\ This is considered a warning but the upgrade may be OK.\n2 -> There was\
\ an upgrade status check failure that needs to be investigated.\n This should\
\ be considered something that stops an upgrade.\n"
