Hi everybody, I'm new in Debian 6.0.4 (squeeze). It is running on HP Pavilion dv8000 (DV8211EA)

root@1:/home/papi# uname -a
Linux 1 2.6.32-5-686 #1 SMP Mon Jan 16 16:04:25 UTC 2012 i686 GNU/Linux

This is my problem:

papi@1:~$ df -lh

When I try to extend:
root@1:/home/papi# lvextend -L +5G /dev/mapper/1-root
Extending logical volume root to 5.32 GiB
Insufficient free space: 1280 extents needed, but only 0 available

root@1:/home/papi# lvextend -L +5G /dev/mapper/1-root /dev/mapper/1-home
Physical Volume "/dev/mapper/1-home" not found in Volume Group "1"

I don't Know how to liberate space from '/dev/1/home' to add it to '/dev/1/root'.

Thanks in advanced for your help.

Warm regards,

Reclaim space by clearing out the package cache:
The first removes packages you no longer need (be careful as it can break stuff!) the 2nd clears out the cache. Run as root. If that doesn't get you enough, back up your data and reinstall, giving / more space: 322 MB is way to little! All partitions on my systems (desktop+server) are at least 1 GB, and more if and where appropriate. (even my desktops have a server-like partition layout, separating /, /boot, /var, /usr and of course /home)

In outline the steps are:

1. Shrink the /home file system.
2. Shrink the 1-home LVM using lvreduce
3. Enlarge the 1-root LVM using lvextend
4. Extend the / file system.

The commands to be used in steps 1 and 4 depends on the file system type(s). df -T to display.

Thanks for your quick answer. But I've tried the reinstallation twice, this will be the third and I don't know how to specify the size for root partition. Do you know any URL where explain this?. I'm sorry but I'm rookie in Linux.

Warm regards.

Thanks for your early answer. I'll try it.

Warm regards.
