Dynamic HD not growing?

[bsa]

Hello community,

I have a strange problem. I've had that with WinXP Guest more than a year ago and had something very similar with different Linux guest in the last days.
I created a dynamicly growing disk, let's say 50GB. Installed an OS. Installed some applications (nothing too big).

In the past in WinXP the properties of the disk showed that ~30GB are in use but I get errors, that the disk would not have enough free space to install a software with 100MB. Don't have screenshots or exact error messages, sorry... "long" time ago. Maybe it was something completly different, but I remebered that when the next happened:

Now I have something very similiar on Linux (Ubunt, CentOS, ...). I start an installer and it dies after a second telling me that my /tmp hasn't enough free space to extract tempfiles for the installation. df -h /tmp shows me 1,7G free space. I can install the software on a physical computer with lesser free space in /tmp. So what's the problem?

I don't know what the problem might be. I had the idea, that maybe something in the allocation of the dynamic disk space is not working properly (the physical HD of the host has >100GB free space). But I guess that the forum would be full of complains about that, wouldn't it?

Any suggestions?

Best regards,
Sascha

Post the complete results of df -h

This is from one of the machines (CentOS 6.2). It has a 10GB limit on the dynamic HD.

Code: Select all

$ df -h
Dateisystem           Size  Used Avail Use% Eingehängt auf
/dev/mapper/vg_centdoc-lv_root
                      5,5G  3,6G  1,7G  68% /
tmpfs                1004M   88K 1004M   1% /dev/shm
/dev/sda1             485M   33M  428M   7% /boot

It looks like you are using logical volumes. And from the looks of it the MAX size is set to 5.5G not 10G or is there more that you are not showing?
I would expect to see sda and at lease sda 1 - sda4
