root volume 100% of capacity
 

I was installing Netbeans on my PC using ‘apt-get install’ while my flashdrive was mounted. This action resulted in my root, /, directory increasing to 100% of capacity (from about 20%) and my media directory increasing to 97% of capacity. I believed that I have narrowed the issues down to

1) media is at capacity
It appears that in a logical sense that the files in usb0 are duplicates of usb files, thus the 97% of capacity. However drilling into usb, there are no files; the files resides in usb0. There is a recycle bin there with what appears to be systems files, the names are long numerics. Is it safe to delete these files, I deleted a tracer log file and one other.

2) Root is at capacity
In the root directory there was a NetBeansProjects directory which appears to be a full installation of netbeans. I did not believe this directory belonged in the root directory and I deleted it. No change in the issue

3) Issuing:: xxxxxxx@yyyyyyy:~$ sudo gedit /etc/default/jetty
results in:
(gedit:7677): Gtk-WARNING **: Attempting to store changes into `/root/.local/share/recently-used.xbel', but failed: Failed to create file '/root/.local/share/recently-used.xbel.C6Q9JX': No such file or directory
or
(gedit:4166): Gtk-WARNING **: Attempting to store changes into `/root/.local/share/recently-used.xbel', but failed: Failed to create file '/root/.local/share/recently-used.xbel.MAEHKX': No such file or directory

I ran ‘apt-get clean’.

Also, issuing root@yyyyyyyyyyy:/# ‘du -sch *’ results in the notices below for the directories concerned and these directories are not found on my PC.
du: cannot access `proc/4511/task/4511/fd/4': No such file or directory
du: cannot access `proc/4511/task/4511/fdinfo/4': No such file or directory
du: cannot access `proc/4511/fd/4': No such file or directory
du: cannot access `proc/4511/fdinfo/4': No such file or directory

Is there some way these issues can be addressed.
Thanks

How about - and use tags when posting the output

regarding the backup - ??
I have copied my work files and folders and I am prepared to start again from scratch if need be

your root partition is only 307Mb! It's full! :( Note that it will also contain /etc, /bin, /opt, /sbin, /boot

Play Bonny!

hattip:

Here is what I see:
root@yyyyyyy:/# pwd
/
root@yyyyyyy:/# ls -a
. dev lib mnt .pulse-cookie sbin tmp
.. etc lib64 opt .rnd selinux usr
bin home lost+found proc root srv var
boot initrd.img media .pulse run sys vmlinuz

root@yyyyyyy:~# pwd
/root
root@yyyyyyy:~# ls -a

. .bash_history .config .gnome2 .mozilla .synaptic
.. .bashrc .dbus .gnome2_private .netbeans
.aptitude .cache .gconf .java .profile

If I didn't say it before: Appreciate your help!

WHY did you only give your root partition 323 MB?

Of course it's full, it's never not going to be full with any modern Linux distro...that's WAY too small.

I believe that I followed Linux installation instructions. What can I do about it now?

Depending on your installed programs, customizations... Re-install whole system may be quicker

It is not clear what "/dev/disk/by-uuid/d4b07556-658a-4b62-a895-d1cb8c70786d" is... (sda[X]?)

If you want to keep the system maybe use that /var partition for / and don't use separate var partition?

Althought I thought my system was working pretty well; I will opt to reenstall it. Any suggestions of what size the root directory should be?

Thanks!

I thought the material in the attached website, just Google it, was intriguing relative to resizing my root directory without destroying my work

You can also download gparted-live-cd & shrink /home from the left, move the rest of your partitions to the right, shrink, the extended partion from the left & grow the / partition to the right.
I usually make / atleast 2Gigs so that I can add a few things to /opt.
To get 2gigs for your system I calculate 1024*2=2048-323=1725M, this is what I would shrink /home by.

Thanks, I will try that before repartitioning my drive.
