We (HP) would like to use multipath i/o with the cciss driver. (which is a block driver). We can use the md driver for this. However, we cannot boot from such a multipath device. Lilo and grub do not understand md multipath devices, nor do anaconda or other installers. (Enhancing all of those, I'd like to avoid. Cramming multipath i/o into the low level driver would accomplish that, but, too yucky.) If there is work going on to enhance the multipath support in linux it would be nice if you could boot from and install to such devices. -- steve - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
