And OpenDFS doesn't exist, the name only every appeared in some mail posts regarding the free software license release of an old DCE version. Now when people talk about a cluster filesystem for oracle they usually mean a shared storage filesystem. Available as proper free software for that are ocfs2 and gfs in the mainline kernel tree, and both have been used for oracle clusters and the vendors promote them for that useage. Lustre is also commonly called a cluster filesystem, but works very differently, I would rather call it a massive-parallel distributed filesyste. (Open-)AFS and DFS also fall into that distributed filesystem category, but they are a lot less optimized for HPC or big commercial workloads than lustre. GPFS also falls under the shared storeage filesystem category, but it's not ported to 390 and a port would be rather non-trivial due to some of it's design decisions. The GPFS kernel code is now in theory available as free software aswell, but the IBM codedrop I have is not actually buildable, and it lacks the userspace which is very intimately tied with the kernel code. ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390
