[linux-lvm] Mirroring with LVM

[Stephan Mueller]

Hi,

is there any possibility to use LVM to mirror hard disks (Software RAID 1)?

Thanks a lot for answer

My understanding is that you use MD to do the mirroring and LVM is layered
on top to produce volumes... so yes you can mirror but LVM doesn't do it.

So, am I right to conclude that if I have a (trivial) volume with one
partition
of 2 discs at raid1 or 3 at raid5 and want to extend that I have to add
another
3 discs for my volume-on-to-of-raid5 or 2 for the mirrored set (mix
maybe)?
It seems possible to add one physical partition but if that disc crashes
I would
loose all data since the filesystem would depend on information on both
partitions
(the physical and the raid abstracted d.o.), right?

Another question. I'm trying to compile the utilities on a glibc 2.1
system,
with no success. The LVM-home page mentions that a small patch is needed
but
I can't seem to find that anywhere ..... suggestions anybody?

Cheers,

Jarek

Hi,

I heard there was a system to do mirroring with LVM.
So one LE points to 2 differents PE.

Is it really possible ?

Thanks

There is no Logical Volume mirroring as yet.
This is subjet to the LVM2.2 release late this year.
