Here is a sample of the errors: Free blocks count wrong for group #1 (14705, counted=19112). Fix? no Free blocks count wrong for group #2 (12753, counted=11404). Fix? no Free blocks count wrong for group #3 (20531, counted=17213). Fix? no ... Free blocks count wrong for group #11160 (7673, counted=3577). Then some errors about inode and directory counts wrong. I also forgot that I have a log of the fsck errors when I had this problem before. > > > Any tips to debug this? > > Can you reliably replicate this problem?

The system is a mythtv box so it happens to poweron/poweroff on a regular basis to record. -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
