[cobalt-users] RAQ3i - out of space, but really shouldn't be

[jale@xxxxxxxxxx]

Good morning, what a way to start a day.

My Raq3i is telling me / is full - but I think something I did is causing 
the message. I have a 2nd drive in the machine and one per week I have been 
using dd to copy drive to drive. Here are the commands I've been using:

dd if=/dev/hda1 of=/dev/hdb1
dd if=/dev/hda2 of=/dev/hdb2
dd if=/dev/hda3 of=/dev/hdb3
dd if=/dev/hda4 of=/dev/hdb4

So instead of typing them in one at a time, I created a small text file 
with the 4 commands in it, ftp'd this file to my RAQ and ran it from root.

After the 1st line completed, the last 3 lines all failed saying the system 
was out of disk space, so I just figured it didn't like the way I made my 
batch file and I typed in the lines one at a time. That seemed to be going 
just fine but then I got in an ADMIN email saying / was out of space.

I did a df and sure enough, it shows it is out of space. I deleted about 
18meg of files and it still says out of space. Active monitor was flashing 
when I went into the GUI, DISK was red, but when I went into DISK, both 
show as green, with / saying it has 179 meg free, but df still says 0.

Now what I found is that I have a file created today called /dev/hdb1 owned 
by root that is 258meg ... but all the other files are very tiny, ie: 
/dev/hdb2. The other item of interest is the permission on the good entries 
start with a b (lower case b) and the bad file is - (hyphen). I tried to 
just delete the file and get File Not Found.

SO - I think I may have found the answer to why it got created, it probably 
has an invisible character of some kind in the name, probably a typo of 
some kind in my batch file ... and I don't  think I can just rm hdb* as I 
have hdb10 and other files, and I don't know where the invisible character 
might be, like right after the h.

*****  Is there a way to see if a file name has an invisible character in 
it? ******
If I can delete this file, the rest of this message becomes irrelevant I 
would believe.

----------
I did mount on my hdb1 (backup drive) and df on that looked fine with 
available: 253042 66% in use, but I'd expect that.

Now I went to unmount my backup drive - maybe I don't remember my unmount 
command, I thought it was either umount mnt or umount /mnt - so I tried 
both, and what I get back is:

error writing /etc/mtab.tmp: No space left on device

So I did an ls -l on that file as get:
-rw-rw-r--   1 root     root            0 Nov  2 09:13 /etc/mtab.tmp

----------------------------
This is from the GUI:
			Total Space 	Free Space 	% Used			
OS and Programs 	920.0 MB 	179.7 MB 	80.5
Virtual Sites 	         11643.1 MB 	9122.6 MB 	21.6
home 			10917.1 MB 	8875.5 MB 	18.7
-----------------------------

So, what do I do? Why does the GUI think I have space and df does not? Any 
clues on how to delete this 258meg file that doesn't seem to want to go away?

Do I put my backup drive in as primary (use my backup)???

You all know how much assistance is greatly appreciated as I am really 
confused.

Thanks!!
