[SOLVED] No Space warning

[timgood]

I have a fresh install of Mint Debian on a 2TB hdd with 20GB of swap and the rest configured as /

My machine has a 500GB hdd with backups of my music and previous home folder from a Ubuntu installation. I have installed duplicity and deja-dup in an attempt to restore my files to a seperate folder called 'Restore' in my home directory. I have mounted the 500GB and told deja-dup to restore the files. It starts to do so, does about 3 files and then I get the message 'No Space Left in 'Restore' despite the fact that there is about 1.8TB shown free. I have also tried to restore the files to a folder on the 500GB hdd with the same result.

Am I doing something silly?

Deja-Dup uses /tmp to write files and if you have large ones, like VBox HDD's /tmp will rapidly run out as it is configured as a virtual file system by default using tmpfs.

So I disabled tmpfs by

Code: Select all

sed -i "s/^\(RAMTMP\=\).*/\1no/" /etc/default/rcS

and then rebooting. However my / partition was still too small to restore the VirtualBox files, so I deleted /tmp , created /home/tmp with the appropriate permissions for read and write, and made a symbolic link to /tmp by

Code: Select all

ln -s /home/tmp /tmp

The restore is now in progress!

I don't know what the question was, cannot mentally simulate your disk setup and the process you are executing..

..You found the space in the usual place (/home .. which will include anything you want to add up to the MAX space you have available..)), but you didn't start by saying you were using virtualbox
--and despite the descriptions given: the exact nature of your setup for hard drives still eludes me

Silly me, I guess..

I'm not using virtualbox for Mint Debian. I followed a partitioning guide for install of Mint Debian and my setup is:

500mb /boot
10GB /swap
48GB /
remainder allocated /home

My problem was this: in the default install /tmp is created as a 'virtual' file system, google tmpfs. It is limited to a percentage of your total RAM, in my case it was set to around 750MB - ample space for most tasks.

However I had created an encrypted backup using deja-dup under Ubuntu and it was these files that I was trying to recover. They include a couple of virtualbox hdd's for my VB version of Windows XP and other Linux OS's I was playing with. These are quite big files, the XP one is in excess of 20GB.

Because deja-dup writes the files to /tmp before restoring them, it was rapidly running out of space and thus falling over. This is why I had to stop the tmpfs system at boot. My / partition was also not big enough for the 68GB of VBox files, so I had to symlink /tmp to my /home partition. Having recovered my files, I have now restored the /tmp directory to tmpfs.

Deja-dup is not particularly good at error messages. Instead of telling me that /tmp was full, it told me that there was not enough space in my home directory, which of course is not true. So it took me some time to track down the cause and correct the backup recovery.

I hope this is now clear.
