/efi/boot (a) must be fat32, and (b) must be a "top level" partition.
Right, the UEFI firmware would not be able to read an EFI partition
inside a partitioned software RAID array, and even on most unpartitioned
RAID arrays. The most you can do is create a RAID1 array with superblock
1.0 and use it all as an EFI partition but registering EFI boot entries
for each EFI RAID member will be tricky.
swap - why mirror it?
For redundancy, of course.
If you set the fstab priorities to the same value,
you get a striped raid-0 for free.
Without any redundancy. What is the point of setting up RAID1 for all
the rest and see your system crash pitifully when a drive fails because
half of the swap suddenly becomes unreachable ?
I have tried the following:
1. make large partition on each drive
2. set up raid array (2 separate arrays)
3. unable to place partitions on arrays
Should be able to
Yes, RAID arrays should be partitionable by default. But your installer
may not support it. LVM over RAID may be more widely supported.
1. set up the same partitions on each set of drives
(did allocate unused space between each partition)
2. was only allowed one partition from each drive for the array
That sounds sensible. A RAID array with several partitions on the same
drive does not make much sense. You must create a RAID array for each
partition set.
