I believe that if /boot is on RAID1, that md partition has to be on one of the first two disks (eg hda, hdb)?
Is there any problem with having /boot on a RAID1 partition across 4 disks as follows?
/boot / (LVM)hda RAID1 RAID5 hdb RAID1 RAID5 hdc RAID1 RAID5 hdd RAID1 RAID5
The boot loader (GRUB) must be installed in the MBR on a hard disk from which the BIOS can boot. With 4 disks, you can install GRUB on all disks, so you can boot even if the first 2 disks fail.
I think it doesn't matter if /boot is the first or another md raid device. It just must not be a LVM.
What about swap? It is best on RAID1, RAID5, LVM, something else or doesn't matter?
we're using swap via LVM without any performance problems. but my opinion is if a server begins to swap things will get slow anyway no matter what type of disk you're using for swap (maybe excluding flash drives / ramfs).
