USB - Disk free space: 0 bytes

[zzzpt]

I have a problem :

I'm connected via samba to my USB external disk (connected to the router)
And both in windows and the ssh session tells me that the disk is full (no empty space)

> df
Filesystem           1k-blocks      Used Available Use% Mounted on
/dev/root                 2880      2880         0 100% /
/dev/discs/disc0/part1 240292420 240292420         0 100% /opt

This is strange because i've deleted alot os stuff, but there not seems to be any space free

Please help

is it normal that the /share/terminfo takes 12GB ?

I think is too much...
I've deleted now :P

rm * -rf

but still:

df
Filesystem           1k-blocks      Used Available Use% Mounted on
/dev/root                 2880      2880         0 100% /
/dev/discs/disc0/part1 240292420 240286124         0 100% /opt

Hi and sorry my english.

Perhaps, mount type is ro (read-only)?
Check this: mount
The end of line you look the mount type (ro, rw, noatime, etc).

Unfortunaly no:

 mount
/dev/root on / type squashfs (ro)
none on /dev type devfs (rw)
proc on /proc type proc (rw)
ramfs on /tmp type ramfs (rw)
usbfs on /proc/bus/usb type usbfs (rw)
/dev/discs/disc0/part1 on /opt type ext3 (rw)
/dev/discs/disc0/part1 on /tmp/harddisk type ext3 (rw)

 df
Filesystem           1k-blocks      Used Available Use% Mounted on
/dev/root                 2880      2880         0 100% /
/dev/discs/disc0/part1 240292420 240286228         0 100% /opt
/dev/discs/disc0/part1 240292420 240286228         0 100% /tmp/harddisk

What i dont understand is big space that some folders take "/share" +1GB (because ive deleted a folder with 12 GB )

Another problem is that i cant delete anything in my laptop (via wireless) with Vista. " Says i dont have permission...


EDIT:
Just deleted another 4.5GB

Going to try

fsck.ext3

...

Well.... I'm geting a bit crazy with this ....

Now i've unmounted the disk

umount -l /opt

and runned

Why do you have the same disk partition mounted on 2 different locations ?

I dont know :P
Only happened once, now is only mounted once.

 df

What happen if i delete all the folders exept the /home (were i have all my files) ?
I'm thinking off delete, and if necessary to run to make a fresh start :P

Hi zzzpt,

Are you still having issue? Can you share us how to fix it ? I have the same issue this morning, I ran the same fix command and now, I am not able to mount the HD, it tells me Invalid Argument.

[zzzpt]

i went in vacation....
But now im at home and the problem persists :P

Going to delete all the folders in the Disk, except the /home folder(with all my data)

Maybe will reset the router, make the tutorial all again ....

[zzzpt]

.....
Deleted all the folders except the /home

Now i cant mount the partition "Invalid argument"

tryed:

e2fsck -n /dev/discs/disc0/part1

e2fsck: e2fsck_read_bitmaps: illegal bitmap block(s) for MyBook

[sven7]

HI zzzpt,

Same here, after the e2fsck , all my files inside the HD gone and only lost + found directory there, I have to reformate the entire HD and starts again. It is just like a nightmare, I am now not dare to save files into my 320g HD. Just don't want to loss all my stuff again.....

[zzzpt]

i dont even have the lost+found folder

i'm still hoping to recover...

What kind of files do you want to recover? Here's my process for general purpose recovery:

1) make an image with dd_rescue
2) run testdisk on the image
3) run foremost on the image
4) run photorec on the image

Photorec and Testdisk are both by the same author. Foremost is a data recovery tool developed by the US Airforce (I think). Typically I'm just recovering jpegs, movies, documents, etc.

WEEEEEE

SUCCESS

Solution (make backups if you can )
mke2fs -S /dev/ida/c0d0p7

fsck ...

mount



Some more info
Somebody with the same problem resolved this way:

http://shon.org/blog/?p=25

[root@adrock init.d]# dd if=/dev/ida/c0d0p7 of=/big/var.bak.dd
530368+0 records in

Still hosed, but now I have a backup of the burnination. And now for the FIX!!!

mke2fs -S /dev/ida/c0d0p7
mke2fs 1.27 (8-Mar-2002)
Filesystem label=
OS type: Linux
Block size=1024 (log=0)
Fragment size=1024 (log=0)
66528 inodes, 265184 blocks
13259 blocks (5.00%) reserved for the super user
First data block=1
33 block groups
8192 blocks per group, 8192 fragments per group
2016 inodes per group
Superblock backups stored on blocks:
8193, 24577, 40961, 57345, 73729, 204801, 221185

Writing superblocks and filesystem accounting information: done

That did it! mke2fs re-wrote all of the superblocks and group descriptors and I was able to mount in RO mode and copy off the data. After that I was able to fsck and remount the original parition with no problems!

Wow,,, nice that you can recover your data.. i just wonder how it become so easy to crash the data. i am still not dare to put important data in it.
