[gentoo-dev] filesystem problems

i'm using gentoo kernel sources, root filesystem type ext3.

somtimes during untarring archives corrupted files are created. stat returns an io-error on these files.

this happens especially when a parallel process accesses the disc device (df is a good one to reproduce this behavior). 
i don't get any kernel error message so i figure my hardware is ok (and yes, i turned off log caching ;).

do you know this problem or even the cause of it ?

i had "preemtive kernel" enabled and i disabled it now (this was the only suspicious entry in the kernel config i could find, for now).
(of course i'll post if disabling kernel preemtion solved the problem and post a full bug report in case it happens again).

You should be asking gentoo-user about this question ...

Even though you don't get errors, you seem to have a corruption of some kind.

1. you have overheating/clocked hardware which then stresses during cpu 
operations like this.
2. You haven't checked your ext3 partition in a while, boot in single user 
mode and do a thorough fscheck.
3. You might have done too many optimisations on your hdd (using hdparm)
4. You might have a hardware corruption, which could be difficult to tackle. I 
would just in case check the memory (memtest) and maybe the harddrive if you 
can.

Please reply to gentoo-user for further reference.
