upgrade:
|
|
|
|
- A new nova-manage command has been added which will upgrade a deployment to
|
|
|
|
cells v2. Running the command will setup a single cell containing the
|
|
|
|
existing hosts and instances. No data or instances will be moved during
|
|
|
|
this operation, but new data will be added to the nova_api database. New
|
|
|
|
instances booted after this point will be placed into the cell. Please
|
|
|
|
note that this does not mean that cells v2 is fully functional at this
|
|
|
|
time, but this is a significant part of the effort to get there.
|
|
|
|
The new command is
|
|
|
|
"nova-manage cell_v2 simple_cell_setup --transport_url <transport_url>"
|
|
|
|
where transport_url is the connection information for the current message

|
|
queue used by Nova. Operators must create a new database for cell0 before
|
|
|
|
running `cell_v2 simple_cell_setup`. The simple cell setup command expects

|
|
|
the name of the cell0 database to be `<main database name>_cell0` as it
|
|
|
|
will create a cell mapping for cell0 based on the main database connection,
|
|
|
|
sync the cell0 database, and associate existing hosts and instances with
|
|
|
|
the single cell.
