Thank you for your very quick response ;) The segment was unfortunately overwritten with irrelevant files, and the block was not that of the root inode. According to the log, it happened on 20th August 12:22:24. I guess garbage collector mistakenly reclaimed the segment without moving the root inode block to a new place. For debugging, I want to know the content of the DAT block located at #22241917. Could you give me a hand one more time, please? # dd if=/dev/cciss/c0d1p1 of=blk22241917 bs=4k count=1 skip=22241917 # expr 22241917 / 2048 10860 # dumpseg /dev/cciss/c0d1p1 10860 > seg10860.log Thanks, Ryusuke Konishi _______________________________________________ users mailing list [email protected] https://www.nilfs.org/mailman/listinfo/users
