| LVM does not offer *anything* sane if it is only blind LVM
It's statements like this that are most frustrating. You have made assumptions
as to what this person is trying to do rather than answering the question. I
answered the question and posed another question. If he's asking one, it might
be good to know why the question was asked in the first place.

So, the fact that I use LVM on a single disk makes me out of my mind? I do
this because I may miscalculate the disk requirements for one mount point over
another. I don't have the traditional whole disk lv_root volume. I have
seperate LVs for /var, /home, /data, /local-scratch all of which can be resized
at a whim. Oh, and if I get a bigger disk (/data is on a whole disk LVM PV), I
can just do a pvmigrate over to the bigger disk. There are many useful reasons
to have LVM.
| why? because *any* disk failure would be fatal
| having 3 disks that way you have *three times* more likely a complete
| data loss
Sure, here you are correct. If you've gone and done something like place an
Logical Volume across multiple single points of failure you've done something
that may be seen as bad. It's not our place to judge the decision, it's our
place to offer possible solutions to the needs of the user.
| the ordinary uiser *doesn not* need LVM nor can he handle it proper
| the advanced user knows hat he is doing and could select it anyways
Define ordinary user in this context. The user has made no statement to how
ordinary they are. They asked a question. The question was answered and
another question (mine) asked to try to figure out what the OP is trying to do.
| this was, is and will ever be a useless and often dangerous default
There is no proof that this is a dangerous default. LVM works just fine while
offering additional functionality whether used by the ordinary user or not.
Offer up concrete evidence as to how LVM vs partitions is any less dangerous on
any SPoF failure system. I'd be interested to hear it as I myself have not run
into problems with LVM in the past decade or so. Ya, it used to be bad, but
it's much, *much* better than it was.
