Subject: Re: Severe data corruption with ext4

Hello again,

now on the same system (hardware configuration unchanged, except that
I attached a DVD burner yesterday), I got dozens of errors like these:

----------
Mar 22 13:47:33 bakunin kernel: __find_get_block_slow() failed.
block=197478301302784, b_blocknr=0
Mar 22 13:47:33 bakunin kernel: b_state=0x00188021, b_size=4096
Mar 22 13:47:33 bakunin kernel: device blocksize: 4096

Mar 22 13:47:33 bakunin kernel: grow_buffers: requested out-of-range
block 197478301302784 for device dm-14
Mar 22 13:47:33 bakunin kernel: EXT4-fs error (device dm-14):
ext4_xattr_delete_inode: inode 1022: block 197478301302784 read error
----------

Please not that I had run an fsck on the mentioned device only a
couple hours earlier, with no errors found.

Now, does this indicate a hardware problem?
My drives' SMART info reports not a single reallocated sector. But one
drive has a high Hardware_ECC_Recovered count, but I got it that's
nothing to actually worry about. Well, it might indicate bad cabling,
though.
