What Kernel are you using to boot up ? it should be one of the SME Sever (depending on cpu) kernel's NOT the Centos kernel's

Try the non SMP kernel - some motherboards are sensitive to SMP kernels when they are not SMP themselves.

looks like you have (at least) a faulty partition : sdc2
The system was not able to rebuilt the raid , it should have be OK we 2 disks from a RAID5 installation, may be there was some other problems earlier you did not noticed.
As Murphy helps, this partition (disk) was part of the main "data" array (/dev/main/root) and if you really loose two disks (partitions) from the raid, things are done :(
if you loose only one, you might try to boot from a live CD (with raid and LVM support) and look further accessing a degrated array (I won't be of any help for this)

 Kernel panic - not syncing: Attempted to kill init!

This line is becoming my nightmare !
We have encounterred it so many times that I'm now loosing my logic.
Last time (2 days ago) on a server on wich, for the same raison, we had broken the Raid before, and was just working on a single disk.
Have a look in the Biugtracker ...

After reading *a lot* it seems (from CentOS forums) that the pb will disapear with the next version of the kernel ...

Soonly, I hope.

You give me the creeps, I've just finished converting 4 servers to SME Server from different distributions (slackware, debian, ubuntu). They were running fine, but having a unified platform would make the administration tasks a lot easier, and SME Server seemed like the perfect solution. I wonder now if it was a good decision.

Be sure it is.
I've made the same decision about 4 years ago. SME has cross difficulties period during that time but never deceive me. Be confident we will find the trick, the main pb is that it is not possible to provoke this pb so, we just can describe the specific situation when it arrives. But we gain experience and the light will come.

Meh - I have been running these servers from way back on all sorts of hardware in all sorts of configurations with no issues. So have many many others.

Davibou, did you find a solution. I have the same problem.

My server had been just fine for a long time, I came out one morning, it was down and this is what greeted me.
