In the disk partitioner, I can't
1) choose to make the LVM with root and swap be on a RAID 1. Is there
some way to do that, rather than two separate partitions RAIDed?
2) They don't align, so I can't clone /dev/sda to /dev/sdb as a
failover (for /boot and /boot/efi). I've created those two, manually,
and nope, it wiped them out, so I can't clone those two.
Any solutions for either of these? I don't have hardware RAID card on this
box.
My favorite solution to above is: all my filesystems live on hardware
RAID devices. No intermediate things like LVMs or software RAID. Just
GPT label and "simple" partitions (or whatever synonym installer script
is using). I know, you pay a bit more for hardware. But in addition to
having more reliable IMHO system (I know, some people do not agree), you
have simplicity, which also adds to reliability, and to speedy recovery
from failures with much smaller room for blunders and data loss.
Just my $0.02.
