Problem with ext3 filesystem

I did some more test. First I split the raid in two partitions and run
mkfs.ext3 -c for badblocks.

then I tried to copy data on the first partion. after a while i got
errors (around 130gb were on th partition) :

attempt to access beyond end of device
sda1: rw=0, want=3151373440, limit=1464846304
attempt to access beyond end of device
sda1: rw=0, want=2853870672, limit=1464846304
attempt to access beyond end of device
sda1: rw=0, want=1751501064, limit=1464846304
attempt to access beyond end of device
sda1: rw=0, want=2783268072, limit=1464846304
attempt to access beyond end of device
sda1: rw=0, want=2835511344, limit=1464846304
attempt to access beyond end of device


so I googled and found this thread:

http://lkml.org/lkml/2006/10/5/353

I tried the script from there on my partition (whith around 130 gb on it):

dd bs=1M count=200 if=/dev/zero of=test0
 while :; do
        echo "cp 0-1"; cp test0 test1 || break
        echo "cp 1-2"; cp test1 test2 || break
        echo "cp 2-3"; cp test2 test3 || break
        echo "cp 3-4"; cp test3 test4 || break
        echo "od 0" ; od test0 || break
        echo "rm 1"; rm test1 || break
        echo "rm 2"; rm test2 || break
        echo "rm 3"; rm test3 || break
        echo "rm 4"; rm test4 || break
 done


The script was running not more then 10 minutes and I got:

EXT3-fs error (device sda1) in ext3_free_blocks_sb: Readonly filesystem
EXT3-fs error (device sda1) in ext3_free_blocks_sb: Readonly filesystem
EXT3-fs error (device sda1) in ext3_free_blocks_sb: Readonly filesystem
EXT3-fs error (device sda1) in ext3_free_blocks_sb: Readonly filesystem
EXT3-fs unexpected failure: !jh->b_committed_data;

inconsistent data on disk
EXT3-fs error (device sda1): ext3_free_blocks: Freeing blocks in system
zones - Block = 327680, count = 1

Then I create a new fs on the partition without any data on it and
got the same errors while running ths script.

On internal ide harddisk softwareraid-1 but partiton size only 4 gb no
problem with the test script.

The testscript with 10mb file is now running for several hours without
any problems on the sata raid partition.

New Partion with size of 340GB, testscript with 200mb files. Errors:

ock = 65536, count = 1
EXT3-fs error (device sda2) in ext3_free_blocks_sb: Readonly filesystem
EXT3-fs unexpected failure: !jh->b_committed_data;

EXT3-fs error (device sda2) in ext3_reserve_inode_write: Readonly filesystem
EXT3-fs error (device sda2) in ext3_delete_inode: IO failure

And with 180 GB Partition:

EXT3-fs error (device sda3) in ext3_free_blocks_sb: Readonly filesystem

Strange ? I still don't know how to solve the problem.
