Emergency Kernel Update [09/21/2010] - [09/22/2010]


Recommended Posts

We will be updating the kernel on the Jedi VPS node to the latest version between 10:00pm and 2:00am EDT. The reason for this is for security reasons while we do use ksplice the age of the kernel and the time it takes to patch this system at this point makes sense to just update the kernel itself. Even if we had to patch the system the virtual machines on it would have had to be all taken off line in order to do the updates at this point. So we believe it would be wise to just do an actual kernel update.

The maintenance window is for 4 hours but we estimate the down time will only be 5 minutes for the node and between 20 and 30 minutes for all virtual machines to be up and running again.

Date: 09/21/2010 - 09/22/2010
