Well, I'm in pain. Mosix was released this week under GPL. Yeah. Works with 2.2.7. Yeah. Doesnt work with the raid 2.2.7 (2.2.6 patch). Boo. This is the deal: I have a poor mans cobbled together beowulf. Mosix allows for process migration between nodes vi ipc calls in the kernel and lots of other neat stuff. For instance, if you have 10 nodes, a make -j10 would spwan 10 processes and the kernel would automagically spread em out over the nodes. I want this. Bad. Unfortunately, the kernel changes for mosix are pretty big. I'm no kernel hacker, but it looks like it tinkers with alot of the same stuff that the raid patch does. Now, I can get the raid patch to successfuly patch (if i patch include/fs.h by hand) ontop of the mosix mess. Unfortunately, kernel doesnt compile. Is the new raid stuff gonna be rolled into the kernel? if so when? Does someone wanna try a hand at getting the raid stuff to patch ontop of mosix correctly? Software raid is the poor mans raid. Beowulfs are poor mans super puters. Alot of people with beowulfs have their head nodes running software raid as nfs root and /usr /home servers for the compute nodes. Having raid and mosix work together would be a "Great Thing". I'd gladly offer access to my cluster if need be. I'm currently only running raid 0. Is it somehow possible to back pedal to "normal" raid 0 in the 2.2.7 kernel if i already have a "newer" raid 0 partition? If so, how, and what version of raid tools do i need? Just for fun, i compiled 2.2.7 without the raid patch. My raid failed at startip with /dev/md1 - invalid flag or somethign like that... Help. :P Wayde Milas
