After a reboot of a CentOS 6.2 server we are getting a kernel panic with the following error:
Kernel panic - not syncing: Attempted to kill init! Panic occurred, switching back to text console
When passing init=option selinux=0 to the kernel at boot the server will boot without a problem. I have tried searching for what init=option does but I have not been able to find any recourses explaining it.
- Could someone explain what this parameter does?
- Also, as this is a production server are there any negatives/risks in running with the init=option?
I have tried to remake the
dracut which did not work and received the above error upon boot.
As this is a clustered server and the primary server should be identical I have copied the
/boot drive from the other server but this did not solve the problem either. (The other server does not have this behavior)
/boot from backup did not work either.
Could you please help me investigate this problem
- What causes this kernel panic?
- How would you go about resolving this issue?
- What logs (if any) would tell you more information?
- As this is an older install, would an update/upgrade potentially fix this issue?
I would also like to add that the only other possible related issue was that the root disk which was raid mirrored failed and was replaced before this happened.
