I agree....but this would have to be something like what I was talking about
earlier with what I thought that LVM should be able to do eventually.
Dynamic reallocation/re-striping at any raid level.

The impression I got from the LVM FAQ was that LVM will not support
RAID1 basically because md does.  Maybe Heinz can shed some light on
that situation and about the dynamic reallocation/restriping issue?

And not just RAID1.

Yes, the idea is to combine existing modular feature sets like LVM/MD.
With the enhancent stacking support in 2.4 the user has all the flexibility
to stack LVM on top of MD or vice versa.

LVM just supports RAID0 to offer performance.

Constraint in the actual allocator is, that you can't extend a stripe beyond
a PV :-(
We want to remove that constraint in post 1.0 LVM.

If that's done, users can add additional PVs (which can be based on
SW/HW RAID1/5/whatever) and extend RAID0 LVs onto those.

Until then, one can stripe over multiple LVs using MD. Those LVs can be
resized equally in order to resize the striped MD. Care needs to be taken,
that the LVs are allocated/extended on distinct PVs.

There is. Check on freshmeat.net and you should find it.

[linux-lvm] GUI front-end for LVM

[Jason Tackaberry]

Is there a GUI front-end available/in-the-works/planned for LVM?  I
found Veritas' vxva front-end a gentler way to approach the world of
volume management and something similar for LVM would be nice.

If there isn't anything, I might consider throwing one together.

Cheers,
Jason.

Jason,

There are a couple out there. Try searching for LVM on Freshmeat.net

I do see a couple.  None of them appear to incorporate md support, which
would be quite nice.

Imagine a GUI tool that would let you create and manipulate RAID devices
(using md) and combine them or manage them using LVM.  A convenient GUI
to convert an existing non-md/lvm system to say LVM-managed RAID1 would
be impressive too, even if it's a logistical nightmare. :)

Not that I have tons of free time, but I might tinker around with
something this weekend.

Jason.
