Introduction: This document describes step by step approach on what to should we do when MARS appliance is stuck and not responding due to Disc issues.
On rebooting you will see the following message on console and boot process will stop—
Automatic reboot in progress.
/: UNEXPECTED INCONSISTENCY; RUN fsck MANUALLY. (i.e., without -a or -p options)
[/sbin/fsck.ext2 -- /] fsck.ext2 -a /dev/sda1 [FAILED]
*** An error occurred during the file system check.
*** Dropping you to a shell; the system will reboot
*** when you leave the shell.
Give root password for maintenance
(or type Control-D for normal startup):
In order to troubleshoot please perform the following steps—
1. Connect to MARS using console port.
2. Power cycle the box.
3. When you see the error mentioned above, try "ctrl-D"
4. If you still see the error, try to log on by using root password and try the command below:
wait until the system filechecks is complete and it should ask to reboot the box
5. If you don't have "root password", we will have to re-image the box using a recovery boot DVD (in iso format), which can be found at the following link:
Hope this procedure will be helpful. Thanks for viewing.
