Bug#631939: Please also build cmirrord from lvm2 source

[Philipp Niemann]

Package: lvm2
Version: 2.02.66-5
Severity: wishlist

Hi!

With current lvm2 packages comes no cmirrord binary. The upstream source
provides everything needed for the utility.

One would have to add libopenais-dev and libcorosync-dev (this was with
my testing environment) to build-deps and have some rules to place the
daemon file properly, as well as a manpage and some startup script.

Upstream uses cmirrord with RHEL 6.0. Seems to be for production use,
too, as the documentation of RHEL 6.0 doesn't have any warnings or
support exceptions listed in the docs.

I build cmirrord from the current squeeze src package by manually
running configure with --enable-cmirrord and ended up with a binary that
does the job (but I didn't yet test for flaws). It seems that clvmd is
also changed by --enable-cmirrord. I had to use the new clvmd to get
mirroring on the machine.

The daemon is used to have LVM based host mirrors of storage, which is a
key feature of our SAN environment. With cmirrord I am able to have a
multipathed, mirrored and shared storage device which I can use to have
live migration of xen or kvm VM.

Thanks for reading!

Kind regards,
Philipp
