CellCC released by Sine Nomine Associates

Sine Nomine Associates is pleased to announce availability of a volume replication tool for synchronizing volumes among OpenAFS cells within the same organization: CellCC ("Cell carbon-copy"). CellCC is primarily written in Perl; it uses remctl commands and a SQL database for network communication. It is available on GitHub, here.
CellCC is a set of tools and daemons to help you synchronize volumes between AFS cells. A single organization may have multiple AFS cells under its control for any number of reasons, including:
 - Compartmentalizing AFS traffic or failures
 - Raising the max number of RO sites
 - Delegating cell maintenance duties
If an organization has such a setup, they may wish to release a volume to multiple cells. For example, to access an application in AFS from any one of the local cells in that organization, without needing to access any of the other "remote" cells.
CellCC can act as an extended "vos release" in such setups. CellCC synchronizes volumes from a "source" AFS cell to a number of "destination" AFS cells, relying on plain "vos release" to synchronize volumes within a single AFS cell. CellCC also attempts to be robust against failures, allowing for automatic retries of idempotent operations and is capable of detailed status reporting.
Sine Nomine is releasing CellCC under the ISC license (a simplified BSD license). The actual license text can be seen here: https://github.com/openafs-contrib/cellcc/blob/master/LICENSE 
Red Hat 7 RPMs for CellCC are available from Sine Nomine here:
