I've recently had a chance to set up some root mirroring under Solaris (v2.6 & 7) using DiskSuite. In Sun's setup they have to specify a partition (small one like 8-10mb) for a metatable database to help point to partitions to boot from as well as general mapping information. I'm not that familiar with Solaris's startup scanning sequence, and I'm wondering if something similar could work under Linux so as to avoid having a non-raided boot partition with the kernel & other info on it? Now, I admit that mirroring shouldn't be that hard as both bootable parts would be effectively the same then after the kernel loads from whatever partition it would start the raid and then re-sync with the other half of the mirror. RAID 5 would be an order of magnitue harder as there's striping involved. Just curious on what the take of this is. Steve
