attempt to access beyond end of device

attempt to access beyond end of device

[Luca Ferrari]

Hi,
since a couple of days I've got these messages in my logs, is a physical 
problem with the disk?

Apr 13 06:25:12 linux2 kernel: Directory sread (sector 0x20) failed
Apr 13 06:25:12 linux2 kernel: attempt to access beyond end of device
Apr 13 06:25:12 linux2 kernel: 02:00: rw=0, want=16, limit=4


Thanks,
Luca

Which type of disk? Raid? Which filesystem? What says a file system check
(fsck)?
Can you do a dd if=<your partition> of=/dev/null with the same log?
If not, looks like the filesystem is bad.

It is a IDE disk, without software raid, formatted as ext2. Since it is the / 
partition I cannot run fsck immediately to tell you what says, I need to stop 
the machine.

Try fsck.ext2 (or fsck) with -fvn <your root device eg /dev/hda1>.
-n tests in read-only mode.

Ok, here there's the result:

fsck 1.27 (8-Mar-2002)
e2fsck 1.27 (8-Mar-2002)
Warning!  /dev/hda1 is mounted.
Pass 1: Checking inodes, blocks, and sizes
Pass 2: Checking directory structure
Pass 3: Checking directory connectivity
Pass 4: Checking reference counts
Pass 5: Checking group summary information

      30 inodes used (1%)
       1 non-contiguous inodes (3.3%)
         # of inodes with ind/dind/tind blocks: 10/6/0
    6937 blocks used (86%)
       0 bad blocks
       0 large files

      18 regular files
       2 directories
       0 character device files
       0 block device files
       0 fifos
       0 links
       1 symbolic links (1 fast symbolic links)
       0 sockets
--------
      21 files

it seems correct, isn't it? I've tried also to dd to /dev/null and it worked 
well:
16002+0 records in
16002+0 records out
8193024 bytes transferred in 0.454885 seconds (18011202 bytes/sec)

any idea?
Thanks,
Luca

Humm, is it possible, that the device was a floppy?
ls -l /dev/fd0* or cat /proc/devices show you, that
the block device 2:0 is the floppy device.
Check this first.

Maybe you're right! I've found that /dev/fd0 was mounted, now I unmounted it 
and I will check the logs.
Thanks,
