Upgrading v2.x PFS Shares
By default, when you configure PFS shares with SteelHead software v3.x or later, you create v3.x PFS shares. PFS shares configured with SteelHead software v2.x are v2.x shares. V2.x shares are not upgraded when you upgrade SteelHead software.
If you have shares created with v2.x software, Riverbed recommends that you upgrade them to v3.x shares in the Management Console. If you upgrade any v2.x shares, you must upgrade all of them. After you have upgraded shares to v3.x, you can only create v3.x shares.
If you do not upgrade your v.2.x shares:
Do not create v3.x shares.Install and start the RCU on the origin server or on a separate Windows host with write‑access to the data PFS uses. The account that starts the RCU must have write permissions to the folder on the origin file server that contains the data PFS uses. You can download the RCU from the Riverbed Support site at https://support.riverbed.com. For details, see the Riverbed Copy Utility Reference Manual.In SteelHead software v3.x or later, you do not need to install the RCU service on the server for synchronization purposes. All RCU functionality has been moved to the SteelHead.
Configure domain settings, not workgroup settings, as described in Domain and Local Workgroup Settings. Domain mode supports v2.x PFS shares but Workgroup mode does not.For details, see the SteelHead Management Console User’s Guide.
Starting from RiOS v7.0.0, PFS shares are synced using a CIFS client on the SteelHead. This mode of syncing does not support PFS v2 shares. RiOS upgrades any PFS v2 shares to v3 when you upgrade the SteelHead image to RiOS v7.0.0 or later. The option to create v2 shares is provided for legacy purposes and might not always be available.
