add libzypp capability to extend LVM on demand

Feature state

Hackweek V
Unconfirmed

Description

LVM (Logical Volume Manager) is designed to mange your disks in flexible way. This means, allocate and use only needed space. And keep unallocated space for further tasks.

It would be great if libzypp can extend logical volume on demand (space required for package installation is already known)

Scenario:

1)there are logical volumes within VolumeGroup (/var, /usr,/tmp)

2)VolumeGroup have free PhysicalEextents

3)logical volume have no free space for package install

4)Install package/packages which requires 12Mb in /tmp, 40Mb in /usr and 16Mb in /var

4)libzypp will extend logical volumes and file systems /tmp by 3 Logical extend, /var by 10 Logical Extents and var by 4 Logical Extents

Layering violation.

Maybe. But should improve user experience if done carefully, no?

Just don't make it do unexpected things. The last thing a sysadmin wants is that space is "stolen" somewhere else (e.g. free space in a VG) when it attempts to expand a LV.
