Installer automatic partitioning

[diaolin]

In the auto installer i've found such a dimension:

my $swapsize = (($hdgb > 32) ? 4 : $hdgb/8)*1024*1024;
my $space = (($hdgb > 32) ? 4 : $hdgb/8)*1024*1024;
my $maxroot = 96;
my $rootsize = (($hdgb > ($maxroot*4)) ? $maxroot : $hdgb/4)*1024*1024;
my $rest = int($hdsize) - $linuxstart - $swapsize - $space - $rootsize; # in KB


this lets the maxroot to 96Gb if the disk is smaller than 4*96 then
use the 25% of the disk...

I think that it's too much

I've just changed manually the iso but i think it would be better to
ask the user during the installation phase

30Gb of root i think is a big size due to the fact that all the vms
are installed on a separate partition (LVM) that uses the rest of the disk.

Is it possible to change that?


Tx, and my compliments for this great interface.
I've made a presentation with 20 or more sysadmins and all have my opinion
about this solution: GREAT!

Many users make backups using 'vzdump' and LVM snapshots. Its just very convienient to have that data local, and that is why we reserve up to 100GB.

The basic design principle is to keep it simple, i.e. never ask users questions they cannot answer (Average Sysadmin has no idea about the partition sizes needed, or why he need partitions at all).

I guess I would accept a patch adding a special boot parameter 'maxroot', defining the max. root partition size.

Many thanks for that presentation.

Ok, i'll post the patch...

Local backup is like to marry the same woman every 6 month

Ok i'll send the patch

Many thanks for that presentation.

As you heard it's all in italian...

Probably i will find $contributors$

Ciao, Daolin

Sure, but the don't use it as 'backup' - its more like a snapshot.

Probably i will find $contributors$

That would be great

patch....

line 268 of proxinstall

remove
my $swapsize = (($hdgb > 32) ? 4 : $hdgb/8)*1024*1024;
my $space = (($hdgb > 32) ? 4 : $hdgb/8)*1024*1024;
my $maxroot = 96;

and substitute with this:

#patch to pass swapsize and maxroot
open CMDLINE,"/proc/cmdline";
my $row = <CMDLINE>;
close CMDLINE;
my $swapsize = 0;
my $maxroot = 0;
if ($row =~ /swapsize/i) {
$row =~ /swapsize=(\d+)[\s|\n]/i;
$swapsize=$1*1024*1024;
} else {
$swapsize = (($hdgb > 32) ? 4 : $hdgb/8)*1024*1024;
}

my $space = (($hdgb > 32) ? 4 : $hdgb/8)*1024*1024;
if ($row =~ /maxroot/i) {
$row =~ /maxroot=(\d+)[\s|\n]/i;
$maxroot=$1;
} else {
$maxroot = 96;
}

#end cmdline parameters



In this manner you can pass maxroot=30 and swapsize=8
thus you can have a 8Gb swap and 30Gb partition fixed at boot

Ok, will include this in the next release.
