Indeed.

Me too, I have everything in (software) RAID1.
mdadm has been really solid for me so far.

Rock-solid for me. There are just a couple of annoying bugs in YaST2's
partitioner we should get rid of before pushing those options to a wider
public (e.g. as the default setup/proposal).

I don't recall 100%, but from what I remember: when you want to combine
RAID1 and LVM, in YaST2, you first have to create the RAID1 (obviously).
Then, don't assign it (/dev/md0) anywhere ! It is assigned by default
AFAICR, so you have to explicitly remove the assignments. Then go to LVM
and there are a few glitches with selecting RAID1 as a PV for LVM too..
I think... sorry, can't explain it in detail, I just had to jump through
a few hoops and don't remember it.

There's also a *very* annoying bug with YaST2, when you resize
partitions, YaST2 will never allow you to do so on a mounted filesystem,
although it works perfectly well on the CLI - at least with LVM +
reiserfs or XFS (lvresize && resize_reiserfs).
