I just saw what appears to be a data corruption problem on one of my
boxes. I'm not sure at this point exactly whats happening, but I
thought I'd warn people that there might be a problem.
Software
Latest FC6 with updates as of last night, running 2.6.19.***. No LVM,
no raid, 3 drives, 1 IDE, 2 SATA.
Hardware
Older Intel P4 on a VIA based motherboard. This system has been
totally stable for about 2 years and I use it daily without seeing any
problems.
[1] Seagate IDE drive on a VIA 8235 controller, system boots from this
disk and it holds the /home partition.
[2] Maxtor SATA drive on a Promise TX2300 controller mounted on
"data2" in my home directory.
What I saw
On the IDE drive, in my home directory, I have a directory ("DVD")
holding three dvd ISO images. I wanted to move the images to the SATA
drive because the IDE drive was getting full (80% used).
I copied ("cp -a DVD data2/DVD") the 3 DVD images (27 GB) from the IDE
drive to the SATA drive. After the copy, I did a "du" in the source
and destination directories. All of the destination files were smaller
than the source files. I checked /var/log/messages and didn't see any
errors.
At that point, I had to leave for work, so I haven't done any more
investigation. When I get back home, I'll of course retry the copy.
Anybody got any clues about what I should look for / try next?
Thanks,
John
