OpenSSI 1.2.1 is a stable release, suitable for production use. A bug that prevented clusters larger than 32 nodes has been fixed. Processes with open /proc files can migrate. The CVIP can be identical to a physical IP address. Hostnames in etc/cvip.conf are allowed. CFS can stack on ramfs. Some documentation has been improved, covering topics such as NFS, LTSP, and NTP.
OpenSSI 1.2.1 is available for Fedora Core 2, Debian Sarge and Red Hat 9.
