Release Notes: Many bugfixes were made. Some highlights include a bug that prevented the X Window System from starting on a node that crashed and rebooted, incorrect CPU times for remote processes, incorrect ttys for migrated processes, various problems with the migrate(), rexec(), and rfork() system calls, issues with the shutdown and clusternode_shutdown commands, a deadlock in the NFS server, and bugs in the clusterwide /dev/pts. Kernel debugging code has been disabled to prevent annoying messages. A troubleshooting guide for CVIP and HA-LVS has been added.

Release Notes: This is the first release from the new "stable branch" of the project's code repository, which will get more bugfixes and documentation than feature enhancements. The kernel debugger is turned off by default, and any node that panics will automatically reboot after fifteen seconds. New documentation includes an Administrator's guide, a couple of READMEs, and some man pages. Several kernel memory leaks and deadlocks have been fixed, as well as some failover bugs. Migration issues for processes with open ptys have been resolved. Some improvements have been made to redhat-config-network.

Release Notes: This version includes an enhanced redhat-config-network that protects the cluster interconnect from being modified, new commands for managing CDSLs, Lustre support, instructions for using OpenSSI with LTSP, an ssi-rmnode command for removing nodes, an improved upgrade script, more documentation, various kernel enhancements, and many bugfixes.

Release Notes: This version's kernel is based on Red Hat's 2.4.20-30.9. It adds NTP support, online help features in the installation and addnode scripts, a README about networking, a fix for a load-leveling panic, an OpenSSI-specific Apache configuration, and a source of entropy for /dev/random.

Release Notes: This is the first release to feature an upgrade script, so that you do not have to uninstall an old version of OpenSSI before installing the new. This release includes various enhancements, such as failover and iSCSI support for root and non-root filesystems. It also comes with cluster-aware versions of strace and the ps command. Something new is a simple timesync mechanism to synchronize the time across the cluster to within a second or two. Included for convenience are required base packages that Red Hat does not install by default. Finally, several bugs have been fixed.

Release Notes: This release features simple configuration of root filesystem failover, improved installation tools, man pages for almost everything, and integration with Red Hat's 2.4.20-28.9 kernel.

Release Notes: Better support for running the X Window System on each node of the cluster, a new localview command that allows programs such as ps or top to see only local processes, support for machines with more than 1 GB of RAM, and faster cluster shutdown. Nodes that are kicked out of the cluster are now automatically rebooted. Many bugs were fixed, including several process-related issues and some triggered under load. A new six-page overview was also included.

  •  16 Oct 2003 21:24

Release Notes: This release supports Red Hat 9, GRUB, and NFS server. New commands include clusternode_shutdown (shuts down a single node), nodename and clustername (replaces node_hostname), and ksync (replaces cluster_lilo). An enhanced mkinitrd replaces cluster_mkinitrd. Clusterwide RC script support has been improved. Restrictions on process migration have been loosened. File descriptors can be passed between processes on different nodes using Unix domain sockets. Various bugs have been fixed, including NFS client mounts, fsync() and rename(), and permission checking for signals and SysV IPC.

  •  11 Jul 2003 00:43

Release Notes: In this release, the source code has been reorganized, and has a new procedure for installing. NFS client support was added. Processes linked to libpthread can now be migrated, including Perl. The SSI-enhanced / dev filesystem has been improved. Two new commands, openssi_cluster_create and openssi_addnode, are alternatives to the old addnode command. The SSI-enhanced LVS has new interfaces for specifying load-balancing weights. LVS director nodes can now be servers. Various bugs were fixed.

  •  19 Jan 2003 23:20

Release Notes: This release includes a first cut of HA-CFS for non-root file systems. The bind() system call now automatically registers a socket with IPVS. The permissions were changed for the /proc/cluster/nodeX files so that everyone can read them. The ypbind daemon now works correctly thanks to a CFS fix. Various process signalling fixes were done, along with other miscellaneous bugfixes. It includes Cluster Tools 0.8.0.
