Bug#704759: Enable lmetad when building lvm2

[Frank Loeffler]

Package: lvm2
Version: 2.02.98-1
Severity: wishlist

Hi,

I have a setup with hot-plug drives with LVM on them and would like to
have them automatically activated when plugged in. The way to achieve
this, at least according to what I found on the web, is to make lvm
aware of hotplug events, and the way to do that is to let it use
information from lvmetad using 'use_lvmetad=1' in /etc/lvm/lvm.conf.
This option is described even in the package for wheezy, but I didn't
find 'lvmetad' in the lvm2 package.

Looking at the source package in unstable I didn't find the
corresponding '--enable-lvmetad' option to configure, and I found this
in the Debian build log:

checking whether to build LVMetaD... no

I can understand why lvmetad might not be enabled by default. Is there a
reason not to build it? (This is not rhetoric; I really like to know
whether there is a reason not to build it.)

Even if it is now too late to get anything like this into wheezy: it
would be nice to have a patch which enables lvmetad so that someone can
either build their own package easily or maybe even get it later from
backports, should it enter there.

thanks, Frank Loeffler
