Release Notes: This pre-release fixes a number of bugs affecting the HA-CFS cluster filesystem, VPROC process management, and HA-LVS IP load-balancer. The kernel no longer uses 4K stacks by default to simplify DRBD-SSI installation without recompiling the kernel.
Release Notes: This release adds port-level load-balancing and dynamic nodes. It fixes many minor bugs.
Release Notes: This is a stable release, suitable for production use. A major bug that was fixed had prevented nodes from joining after failover of the init node. Also, a shmat() permission bug for non-root users has been fixed. There is a fix for the Debian version of OpenSSI to support long device names with DRBD.
Release Notes: This development release is based on the 2.6.10 kernel. HA-LVS was enhanced to allow the selection of load balancing algorithms, to automatically register UDP servers, and to detect eligible servers during start-up. Support for dynamic nodes was added along with the use of DHCP-assigned addresses for the cluster interconnect.
Release Notes: 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.
Release Notes: OpenSSI 1.2.0 is a stable release, suitable for production use. New features include several CFS performance enhancements and the integration of LVS-NAT. POSIX process groups and multi-threaded applications can atomically migrate as a group. Also, processes can migrate while holding file record locks. When clusternode_shutdown is done, loadleveled processes are automatically migrated away. The top command was enhanced to display execution node numbers, to allow filtering by node number, and to have a localview mode. There have also been many bugfixes.
Release Notes: This version is primarily a bugfix release. The top command was enhanced to display execution node numbers by default, as well as to have a localview mode. The ps --shownode and --node enhancements are working again. The init failover state file was moved to improve performance.
Release Notes: This is a development release, and is not necessarily suitable for production use. It has versions for Fedora Core 2 and Debian. New features include several CFS performance enhancements and the integration of LVS-NAT. POSIX process groups and multi-threaded applications can now atomically migrate as groups. Also, processes can migrate while holding file record locks. New commands include "fast" and "fastnode". Several files have been added to /proc/cluster for dynamic modification of nodedown detection parameters. Finally, a variety of bugs have been fixed.
Release Notes: This release is mostly unchanged from the 1.0.0-rc6 release, apart from a few minor bug fixes. A bug involving SEM_UNDO and nodedown was fixed. The process loadleveling algorithm better handles different numbers of CPUs on each node. File locking with fcntl now works for O_LARGEFILE files. The mklocalfile command now sets the correct owner/group on the CDSLs that it creates.
