Re: [Swift] [Keystone] Account migration

 

Keystone was just revised to separate Tenant "id's" from "names".

ID's are now backend-managed (auto-incremented SQL primary keys, for example), while names are read/writable through the admin API.

The same change also applies to Users (and Roles is in the works).

For swauth there is provision to change account_id using swauth-set-account-service, it could be changed to the tenant_id, but since account_id is part of the hashing, old data in that account won't be accessible, i am not familiar with keystone, is there any such service in keystone to change tenant_id, then we can change tenant_id to the account_id, and old account will be accessible.

Without changing the account id, how do I map the uuid of the old account to a Keystone tenant Id?  For a given tenantId, I would like to be able to reference both the corresponding Swift account and Nova project, right?

Why would the account need to change? Can the swift account reference in keystone be set to the old value? If not, then yes you will have 2 swift accounts.

However, the account format has changed (under Keystone).  So, if I have lazy provisioning on (account_autocreate), would I *accidentally* have 2 Swift accounts instead of one?  Ideally, if I can "migrate" all the old account Ids to use the new format, that would guarantee consistency between the old accounts and any newly-created accounts.  Am I missing something here?

Under Keystone (with swift_auth and Swift's lazy provisioning), I see the Swift account now has the format <reseller_prefix>_<tenantId>.  So, if we have existing Swift account data with the old format, how would one go about migrating from the old format to the Keystone format?  Is there a plan to do so within the Diablo time-frame?
