[linux-lvm] Update on LVM2 mirror support

[Alasdair G Kergon]

LVM2 CVS now contains the first version of mirroring support.
This is *not* production-ready!

So far: use -m with lvcreate to make new mirrored volumes.
Default is -m0 (no mirrors); -m1 gives you 2 identical images.

Use lvs -a to list all lvs, including the internal ones.

NB xxchange -an doesn't work yet: you have to remove the internal
LVs separately afterwards with 'dmsetup remove'.


I'm particularly interested in hearing about any existing features
that the recent changes have broken:-)
