Hi all,

Apologies if this is a noob question, but I’m running into trouble using sshfs to mount a remote folder (ubuntu 12.04 LTS; x64). The basic problem is that the remote folder is quite large, and although there isn’t a problem initially, over a medium to long time I start getting errors indicating that root is running out of disk space. I assume that the OS is incorrectly counting remote files as local ones (that’s what it looks like from the Disk usage analyzer), but I’m not sure how to prevent that from happening. The commands I’m using to mount the remote folder are:

ssh hostname -l uname -Nf -L 20400:homemount:22

sshfs -o UserKnownHostsFile=/dev/null -o StrictHostKeyChecking=no -p 20400 \
uname@localhost: ~/Desktop/PPS_Cluster/

Is the problem that I am mounting to the desktop? Intuitively it seems like this shouldn’t be an issue, but perhaps someone clever can tell me what I am doing wrong.

How can I make use of this free space? I have 35g available but I’m not sure how to get use of it.
Please see the image.

Thanks,
Wayne

A process filled the HDD while performing a kernel upgrade. I then couldn’t graphically log in although there was a gui login (but not the normal one, the theme was different)
I attempted to delete files but whenever I rm’ed a file it didn’t seem to show up as freeing up space when I checked with df.
I even logged in as root on tty1 as well as using the failsafe kernel.
Each time my attempt to free space by deleting files didn’t seem to work.
Why couldn’t I rm files? Is there a solution?

I "solved" the problem by changing the reserved space for root (tune2fs) to give myself some space to work. I then was able to graphically log into Gnome and delete some files and free up some space. I then put my reserve space for root back so I have a way out in the future.
However I’m a little concerned as to how I’d have solved this problem had I not had the reserve space trick up my sleeve.
Thoughts & suggestions appreciated.
