File system corruption tests continued with new operating system: This is an ext2 file system on Linux version 2.1.29. Spare disk, 98% full of a file called ZERO, from `cp /dev/zero /mnt/ZERO` /dev/sdc1 893986 832547 15254 98% /mnt # ls -la /mnt total 832548 drwxr-xr-x 3 root root 1024 Mar 11 18:24 ./ drwxr-xr-x 21 root root 1024 Mar 11 18:00 ../ -rw------- 1 root root 849182720 Mar 11 18:29 ZERO drwxr-xr-x 2 root root 12288 Mar 10 15:27 lost+found/ # cmp -l /mnt/ZERO /dev/zero &> xxx & # head xxx 94295041 17 0 94295042 17 0 94295043 17 0 94295044 17 0 94295045 17 0 94295046 17 0 94295047 17 0 94295048 17 0 94295049 17 0 94295050 17 0 # tail xxx 94384120 17 0 94384121 17 0 94384122 17 0 94384123 17 0 94384124 17 0 94384125 17 0 94384126 17 0 94384127 17 0 94384128 17 0 cmp: /mnt/ZERO: I/O error # Normal (EOF)
This shows file system corruption starting at byte offset 94295041. This means that the last good byte was at 94295040. 94295041 / 1024 = 92085. I don't know what this means. Bet it isn't good, though.
