FreeBSD panic: no init

A

aceman

I have a machine which has freebsd FreeBSD 8.2 and gmirror installed on it. It has been running for some time, today it got a power failure and got rebooted.

When it reboot it says
Code: 
mountroot>

The mountroot options are:
Code: 
ufsid/<somenumber>
ad0
ad1

I enter:
Code: 
ufs:ufsid/<somenumber>

then it displays:
Code: 
panic: no init
no init found in: /bin/init /sbin/init.bak ....

Please let me know if someone has any solution.

You could boot from an 8.2 LiveFS CD and then # kldload /path/to/file/geom_mirror.ko, mount your filesystems, and then restore /sbin/init from your backups (you do have backups, right?) or copy the one from the LiveFS CD (restoring a backup copy would be better, particularly if you've updated your sources and rebuilt world).

Note that files (particularly ones not being written to at the time of the crash) don't just disappear on their own. I suspect there may be something else wrong with your system which you'll only find after you restore /sbin/init and try booting again.
 
I fixed it by changing some BIOS configuration from IDE type to AHCI. I do believe the previous configuration was using IDE, but now it uses AHCI.

Can someone enlighten me?

But the error
Code: 
Panic: no init
is gone and the server is up and running again.
