| # fx disk-extract-serial-log |
| |
| Extract disk image from serial logs. |
| |
| ```none |
| |
| When filesystems are corrupted, it may happen that we lose abiility to ssh into the system |
| to debug. In such cases, we may want access to filesystem metadata to debug the problem. A |
| board or product may write filesystem metadata to serial. |
| This script helps to identify and extract metadata written to serial. |
| |
| Since scraping logs is prone to error, this script may fail if format of log changes. For |
| reference, |logs| under function test() contains a real example log with which the script |
| works. |
| |
| There are multiple ways to get serial log including `fx serial`. The output of serial log |
| should be stored in input file. |
| |
| usage: fx disk-extract-serial-log --input FILE --output FILE |
| |
| --input Extract disk image from serial logs. |
| --output Path where extracted image will be created. |
