Quota check command fails after deleting volume types:: The `cinder-manage quota check` command fails when processing projects that previously used deleted volume types. The failure occurs when the command is run without the `--project-id` argument, due to orphaned quota records in the database from deleted volume types. + *Workaround:* Use one of the following workarounds: * Use the `--project-id` argument to check specific projects that do not have deleted volume types. * Manually clean orphaned quota records from the database before running a system-wide check.
