rethinkdb index-rebuild: Connection refused

I recently decided to finally upgrade from v1.15 to v2.2.1, created a clone of the server, and intuitively upgraded rethink using apt.

But now something strange happens: rethinkdb service won't start because of old indexes, and index-rebuild screams it can't connect.

What am I missing?

$rethinkdb --version
rethinkdb 2.2.1~0precise (GCC 4.6.3)

$ service rethinkdb start
rethinkdb: default: Starting instance. (logging to `/var/lib/rethinkdb/default/data/log_file')

$ cat /var/lib/rethinkdb/default/data/log_file | tail -1
2015-12-09T14:16:47.011883463 0.051804s error: Encountered an index from before RethinkDB 1.16, which is no longer supported.  You can use RethinkDB 2.1 to update your secondary index.

$ rethinkdb index-rebuild
Error when connecting: Could not connect to localhost:28015. Error: [Errno 111] Connection refused

To upgrade from v1.15 to v2.2.x you will need to first upgrade to v2.0.5 as pre v1.16 indexes can't be rebuilt with versions greater than v2.0.5.

so the process goes:

  1. Upgrade to 2.0.5
  2. Rebuild Indexes
  3. Upgrade to 2.2.1 (or latest version)
  4. Rebuild Indexes

Note: When indexes are rebuilt, they are done in memory, so if you have large tables, or lots of indexes, make sure you have enough memory or do them one at a time.
