If I understood correctly, disabling write back cache must be done on the device (ie disk). However, the script I pointed in comment 19 tests the filesystem creating it in RAM. However, I also tried mounting with data=ordered instead of data=writeback (default), but it didn't affect the results.
Kernel 2.6.31-rc4 fixes the problem. Note that 2.6.29-rc1 also fixes it, if you want to check an earlier version. I also did the same test on a 32 bits virtual machine and got the same results using default kernel for Ubuntu 9.04 Server (2.6.28) and 2.6.31-rc4. -- disk corruption ext3_free_blocks_sb: bit already cleared for block 232785 https://bugs.launchpad.net/bugs/209346 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
