Thanks for the script btw. Yes, in principle we can do root on multipath for SLES9. However, as YaST is not aware of udev in SLES9 we cannot say we support it. Sad, but true. > SLES 10 (kernel 2.6.16?) says it supports root-on-multipath (not boot > though), may be a common feature with redhat 5 too? > (I knew people would get this wrong. They always do. Sigh) _Booting_ as something which is provided by the BIOS. And as I haven't seen _any_ BIOS yet which allows for truly multipathed booting we _cannot_ boot from multipath. The kernel and the initrd will _always_ be loaded from a single path by the BIOS. So in that sense we don't support boot from multipath as the BIOS doesn't support it. Once the kernel and the initrd is loaded into memory then of course we'll be doing multipathing. Right from the start. With udev and everything. And please file a bugzilla or drop me a note if it doesn't work.
