Hi,
I've been the victim of a major disk corruption problem. I was running a 2.1.6 kernel from a few weeks, under a moderate load (about 70% of cpu usage 12 hours a day, but this shouldn't be the problem) when I suddenly got a dozen e2fs error messages on the console. I think that was the "bit already cleared for inode ..." error, but I'm not sure.
reboot (cleanly with shutdown, not a reset), fsck in single user mode (disk mounted read-only of course). then a lot of errors (for example lots of block numbers > to my disk size). I didn't noticed any particular bit pattern in this bogus block numbers (they looked like evenly distributed 32 bit numbers). Then a lot of other errors that I didn't even noticed because I was much too bored.
Then a second fsck "just to check that everything got corrected". The problem is, that I got a few new errors ! (but the third fsck was perfect)
Now all of my disk is gone, and all I can see in / is my lost+found directory. I don't see it with ls, but with my shell completion feature :-/
I don't have any hope for my datas, but I think that the fsck problem on the second run had to be reported. specifically, the errors I got on the second run were all related to the ".." entryes of some directoryes. I think that when e2fsck moves a directory to /lost+found, it "forgets" to change the ".." entry. Is this an fsck bug, or am I becoming crazy ?
now a question : is there some known bugs in the 2.1.6 kernel that would explain my corruption problem, or should I doubt about my hardware ? as I said, I didn't noticed any particular bit patterns, but still I'm worried. I wouldn't like this to happen again.
my (dead) configuration : kernel 2.1.6 (with the memcpy patch) e2fsck 1.06 IDE disk, triton chipset (DMA disk access used) P133 with 32 megs (but I doubt this could be important)
