mkdir stuff
mkdir: cannot create directory `stuff': No space left on device

Open in new window


Not sure to understand what the problem is (but I'm by no mean an *nix expert).

Any help appreciated

try "sudo mkdir /stuff"

Just remembered Ubuntu is funky about the root account. It should prompt your for your password (your normal password).

Same problem (running as root btw)

I genuinely think I am out of space - if I do a apt-get update
W: Failed to fetch http://security.debian.org/dists/squeeze/updates/contrib/binary-i386/Packages.gz  Could not open file /var/lib/apt/lists/partial/security.debian.org_dists_squeeze_updates_contrib_binary-i386_Packages - open (28: No space left on device) [IP: 149.20.20.6 80]

You would get access denied if it was a permissions issue.
Did you try df -hi?
Wonder what the chances are you ran out of inodes.

Bingo.  I'm not sure if expanding the volume group will add inodes.  If not, you would have to move files off there.  If you could create another partition and format with a larger inode set then you can relocate your files there.

You can try this:
resize2fs /dev/mapper/turnkey-root

Better yet here is a site on turnkey lvms
