8.1 Using built-in ‘fsck’ to fix disk

fsck is used to check and optionally repair one or more Linux file systems. The file system can be a device name (e.g. /dev/hdc1, /dev/sdb2), a mount point (e.g. /, /usr, /home). If the SATADOM is booted to terminal, then type the following command.

$fsck /dev/sdxx

The exit code returned by fsck is the sum of the following conditions:

0 - No errors

1 - File system errors corrected

2 - System should be rebooted

4 - File system errors left uncorrected

8 - Operational error

16 - Usage or syntax error

32 - Fsck canceled by user request

128 - Shared library error

If file system errors not corrected then re-flash the image in SATADOM which is provided as backup in DVD. To re-flash refer step 3 in Appendix G.
