attempt to access beyond end of device

[Fred Skrotzki]

How big should the drive allocation be that is having a problem?  If it
is bigger then 2 tb, how exactly did you partition it?  If it is bigger
and it's disk label type is msdos that that could be your problem.
Anything over 1.9999 tb needs to be gpt labeled as a disk with msdos
only has a 32 bit pointer to account for disk space up to 1.9999 tb..
 
you can check this using parted.  but be careful as parted modifies the
disk after each operation unlike fdisk for example.
 
you can do the following safely
parted /dev/sda                <---------------- change to point to your
correct drive
print
quit
 
Our output for a 2.8 tb drive looks like this
(parted) print

Disk geometry for /dev/sda: 0.000-2384485.000 megabytes
Disk label type: gpt
Minor    Start       End     Filesystem  Name                  Flags
1          0.017 2384484.983  ext3                              
(parted) quit

Subject: attempt to access beyond end of device


Seeing the following paired kernel error messages:

"attempt to access beyond end of device"
"dm-1: rw=0, want=26553873480,  
                        limit=3786932224"

The server is a PE2950 running RHEL ES 4.4. The system has one
filesystem under LVM, physically living on an AoE storage server. AoE
drivers are up-to-date. Server exports the root of that logical
filesystem to other servers. The server's kernel is 2.6.9-42-ELsmp.

We are seeing odd small-file corruption. Sometimes, this corruption
occurs to static data files after being accessed for read. 

I've not seen info related to this problem on recent Red Hat releases,
or recent kernels for that matter. 

I could use a good starting point for troubleshooting this! This isn't
the only AoE installation I'm working with, but it is the only one using
PE2950s, and the only one with such errors. Thanks.
