Select Pithos storage backend
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Starting from Synnefo 0.15.1 we introduce the ability to select or change the
storage backend. If you have already enabled and configured RADOS as your
secondary storage solution you can now explicitly select your storage
backend being only RADOS.
A new variable has been introduced called PITHOS_BACKEND_STORAGE with
possible values 'nfs' and 'rados', default value is 'nfs'.
For those users that need to migrate from NFS to RADOS and have not enabled the
dual mode of operation from the beginning of their installation a
synchronization script is provided in the 'contrib' directory called
'pithos-sync-rados.sh'
Since this version the dual mode of operation is not supported any more,
meaning you will not be able to keep double Pithos objects anymore in NFS and
RADOS.
After installing v0.15.1 you will have to choose between the storage backend
you want to use.
