At a minimum, it would be nice to have a list of common tasks,
especially in a comparison format (e.g. "Replace a failed drive" with
MD and LVM commands). Maybe this already exists somewhere and could
just be referenced.
I'm not aware of any such document. CC'ing LVM guys to
correct me if
I'm wrong.
I think one thing that's a bit of an annoyance is that LVM RAID is done
at the LV layer, so you have to remember to set it up for every LV you
create, vs. MD RAID where the whole VG will have RAID (this can be
useful in some situations, but probably not the common case). This
should be pointed out in the release notes IMHO.
It's a good idea to mention
this in the release notes, thanks! However,
a linear LV can be simply converted to a RAID LV later so at least it's
not that fatal.
Also: does this apply to /boot partition RAID 1? IIRC that didn't work
with LVM RAID at one time.
/boot on LVM is not supported right now so this is not
concerning /boot at
all.
