Red Hat Bugzilla – Bug 169310
corruption of larger files in software RAID 1
Last modified: 2013-07-02 22:25:40 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
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.
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
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
The kernel is present and when used does indeed fix the corruption problem.
My apologies for crying wolf.
ok, thanks for double checking :-)
