Description Shafer Stockton 2005-09-26 17:10:07 EDT
Description of problem:

When copying four 600MB+ files (ISO's) from one section of the filesystem to
another at least one file is damaged.

Version-Release number of selected component (if applicable):

Seems to happen on all FC4 kernels and even the FC3 rescuecd kernel.

Steps to Reproduce:

1. I downloaded 4 ISO's via bittorrent (it took a while for the files to
checksum correctly, my first hint of problems)
2. Copy correctly checksummed files to another location on the FS (/tmp)
3. Check copies with sha1sum or md5sum (depending on the provided info for
correct checksums)

Additional info:

If I don't start the software RAID and interact with just half the mirror I can
copy files around without a problem.

I'm using software RAID 1 on two disk attached via the sata_via driver. The
motherboard is an ASUS A7V600-X with VIA VT8237 driving the Serial ATA. I tested
my memory for one full pass with memtest86 and things came out clean. I also ran
SeaTools full test on both my disks and they passed.

what is the newest kernel you've tried that exhibits this problem ?
There was a raid1 corruption problem fixed recently.
Comment 2 Shafer Stockton 2005-09-26 18:08:03 EDT
2.6.12-1.1456_FC4 which I'm fairly certain is the latest kernel (at least via
yum).  I tried it after I noticed the corruption with 2.6.12-1.1447_FC4.

Checking the testing directory just now I see a newer kernel. Is that the one
with the fix?

If it is I'll certainly try it. Guess I should have added CLOSED to my bugzilla
searches. Oops.

2.6.12-1.1456_FC4 has the fix I was thinking of, so this is a different problem.
Reassigning to SATA maintainer.

I had the fixed kernel installed and thought I had tested against it. Foolhardy
of me to think such things when I can't access the machine to double check
before replying.

The kernel is present and when used does indeed fix the corruption problem.

My apologies for crying wolf.

ok, thanks for double checking :-)
