It is environment setup error that appears on hosts that already have some artifacts from previous installations. Just update oslo lib "context" correctly.

[Yogesh (ykshirsa)]

This issue is not an environmental issue.
It's a fresh devstack deployment.
You can also see this error here - http://logs.openstack.org/62/301962/2/check/gate-manila-tempest-dsvm-mysql-generic/137825f/logs/screen-m-api.txt.gz

i'm sure it's barfing because '_set_read_deleted' had not been called before '_get_read_deleted'. From what I can tell, oslo.context never has called it '_read_deleted', they have a show_deleted kwarg we do not make use of.

$ cd oslo.context
$ git log -G ".*read_deleted.*"

    Fix Manila RequestContext.to_dict() AttributeError

    During context initialization RequestContext.to_dict() method
    may be triggered before all Manila specific keys have been set
    in the context, in which case an AttributeError is raised.

    Fix to_dict() method to set None values for the Manila specific
    keys in the context when these attributes have not yet been
    set.
