ext3 rsync/cp copying errors - kernel: attempt to access beyond end of device


Hi all,

I'm having some difficulty copying a large amount of data from an XFS filesystem (pre-existing, LVM) to an ext3 filesystem I've made. With both rsync and cp, I can copy a good deal of data (~250GB), but I eventually get this sort of thing in my /var/log/messages:


Code:
...

Here's what I have that may be relevant:

I created a ~14 TB partition (gpt partition table) using parted:

Code:
Using /dev/sdd
(parted) print                                                            
Disk geometry for /dev/sdd: 0.000-22886400.000 megabytes

1          0.017 14000000.000  ext3
I checked for kernel EFI support:

Code:
[mario ~]$ uname -r
2.6.9-89.33.1.ELsmp
[mario ~]$ grep EFI /boot/config-2.6.9-89.33.1.ELsmp
CONFIG_EFI_PARTITION=y


I made an ext3 filesystem using mkfs.ext3:

Code:
[mario ~]$ sudo mkfs.ext3 -c /dev/sdd1
mke2fs 1.41.14 (22-Dec-2010)

This filesystem will be automatically checked every 27 mounts or
180 days, whichever comes first.  Use tune2fs -c or -i to override.

The commands I used to copy were `rsync -aPv <dest> <target>`, `rsync -aPvSH <dest> <target>` and `cp -av <dest> <target>`.

The kernel version is (as seen above) 2.6.9-89.33.1.ELsmp and the box is running CentOS release 4.8 (Final). The originating disk is an LVM2 volume, created from a hardware RAID5 disk array (Dell PERC6 controller). The target disk is a RAID6 disk array attached to the same controller.

I'm not sure what I'm missing here but I figure it is likely something done incorrectly while making the filesystem or the partition. I suppose it is possible that the XFS/ext3 filesystem differences are trouble but that seems like something rsync and cp should be able to handle. I'm not extremely well-versed in all this so any help would be appreciated!

Thanks,

Mario

I've seen the error "attempt to access beyond end of device" once on my computer. It was related to the file system looking for a block that was beyond the boundary of the partition. You should be able to fix it by dismounting the partition and running fsck on it. If that doesn't work then run mkfs on the partition after you copy the data to another partition or device.
