Arla (file system)
Encyclopedia
Arla is an implementation of the AFS
distributed file system
developed at the Royal Institute of Technology
in Stockholm
.
Arla was started by Björn Grönvall in 1993. Assar Westerlund and Johan Danielsson joined the project shortly thereafter. The project died down before it was usable.
In the fall of 1997, the project was restarted, starting with Björn's implementation of rxkad. Assar ported xfs (an arla component, not to be confused with the XFS
filesystem) to FreeBSD
. Love Hörnqvist-Åstrand began working on it, followed by Magnus Ahltorp, working on the Linux
kernel module, and Artur Grabowski, working on the OpenBSD
kernel module.
Today, Arla has AFS client support for OpenBSD
, FreeBSD
, NetBSD
, Linux
, Solaris, Tru64 and Mac OS X
. Windows
support is on the way, delayed by insufficient Windows knowledge. An experimental AFS
server is available, but it is not yet considered stable.
