[linux-lvm] lvm2 debian packages

[linux-lvm] lvm2 debian packages

[Andres Salomon]

I've built experimental lvm2 debian packages.  There are a few kinks to
work out, but they work for the most part (I'm using them now on a
server).

Add the following to your /etc/apt/sources.list:
deb http://incandescent.mp3revolution.net/lvm2 ./
deb-src http://incandescent.mp3revolution.net/lvm2 ./

Run the following:
apt-get update && apt-get install lvm2 kernel-patch-device-mapper;

Patch your linux-2.4.1[67] kernel w/
/usr/src/kernel-patches/all/device-mapper/linux-2.4.1[67]-devmapper-ioctl.patch.gz,
make config, enabled device mapper, compile and install.  If built as a
module, /etc/init.d/lvm2 start will modprobe it in.

Comments welcome.  I've also committed these to cvs HEAD, so feel free
to check out device-mapper/LVM2 and build yourself.

Additional packages include libdevmapper, libdevmapper-dev, and dmsetup.

[linux-lvm] lvm2 debian packages

[Andres Salomon]

For debian users who are interested in testing out LVM2, debian packages
are now in unstable (apt-get install lvm2).  They've been successfully
built for all 10 architectures; I'm especially interested in reports from
people trying out lvm2 on non-x86 archs.

I have tried building a new system with LVM2 and was not able to get it
to boot from an ext2 ram disk, after ensuring the additional dm-mod
module was included and demanded in. Is there a standard boot procedure
builder yet? Is libdevmapper needed at boot time as its normal home is
in /usr/lib rather than /lib?

I then left root as a standard ext2 partition and made some of the basic
directories - tmp, usr and var into lvm'd partitions. The system wouldnt
recognise vgs at first as /var was only a mount point, I had to create
the /var/lock dir for vgscan and vgchange to work. Then the boot script
/etc/init.d/lvm2 failed as it uses things like awk which are in /usr/lib
I was able to manually go back and mount the missing partitions in
maintainance mode so its almost there...

Hope this is of use
Regards
Andy

Try the newer packages (-3), they fix these issues.

Much better,

a blank install, utilising an ext2 root partition now only needs the
device-mapper patch to be bootable, once DM is in the main tree then
I won't be running custom kernels at last!

The only other issue outstanding is that the vgscan process uses
/var/lock if this directory does not exist when the vgscan occurs
then the scan fails. Though I mount /var as an lvm partition I have
created /var/lock from root and this seems to work fine. I havn't
found any problems with that yet.

Initial testing shows it appears robust and it looks like my new server
gets to go into service soon!

Regards
Andy

I've committed some code which should fix this, assuming the problem
you're having is related to mkdir("/var/lock/lvm") failing because of a
missing /var/lock (and not because /var is read-only or something).
