Hi, I am thinking about an OpenSSI two nodes cluster with mirrored disks between the nodes, probably using drbd. I need an uptodate desktop environment, and high availability. I would like to know how stable and reliable is the OpenSSI for lenny. Seeing that it is being kept in the directory called alpha got me a bit worried, since I would like this server to operate without an admin babysitting it. Also, my hardware has a network interface that has a driver only in the latest 2.6.26 kernel, so it probably means that I would have to recompile the kernel for that driver, or could I just install a XEN on the two nodes and run OpenSSI as guest(?) In which case I may also be able to live migrate one of the nodes to the other node for hardware maintenance. Or would the RAM pose a problem in that scenario? (i.e. the first guest will take up all the ram of the machine, so there will be no ram space to migrate the second one in.) In XEN , can I replicate the whole OS via drbd, ie have both nodes boot from the same filesystem? Since drbd is of version 7 in openssi does it not support primary/primary or is it a special version that does? And what about the CFS? say if I put a drbd in XEN, and run OpenSSI from there, can I use OCFS2 or something or do I have to or better use CFS? And last a repeat of the first question, is lenny's openssi in its current version a good solution for high availablity? |
