EXT4 Data Corruption Bug Hits Linux Kernel

Posted by Soulskill on from the plenty-of-time-to-fix dept.

An anonymous reader writes "An EXT4 file-system data corruption issue has reached the stable Linux kernel. The latest Linux 3.4, 3.5, 3.6 stable kernels have an EXT4 file-system bug described as an apparent serious progressive ext4 data corruption bug. Kernel developers have found and bisected the kernel issue but are still working on a proper fix for the stable Linux kernel. The EXT4 file-system can experience data loss if the file-system is remounted (or the system rebooted) too often."

    This appears to be untrue. My latest tests suggest that it happens if a single unclean umount happens while the fs is mounted in 3.6.3. (At least, I saw corruption in /var after a single boot, followed by a rescue boot into 3.6.1 and fsck: every filesystem that had journal replay invoked also had corruption.)
