Scope: We are taking the node offline to perform a Kernel upgrade. This was schedule for a normal maintenance window however it has been changed to emergency status due to repeated crashes. This upgrade will eliminate the previously occuring stability issues.
Explination of the issue:
With the older kernel's using Xen 4.1.2 We have encountered instability with Xen Store and once it crashes causes the node to become unresponsive, this was a know issue in Xen 3.4.4, Xen 4.1.2 Has addressed the issue however the 2.6.18 Kernel does not properly operate with Xen 4.1.2 so we are upgrading the system to Xen 4.1.3 & Kernel 3.5.3 in order to run the latest stable version of both the Xen Hypervisor & Linux Kernel
Affected nodes: DC03R02DS36
If you wish to verify what node your servers are on, you may do so in the VPS control panel. To check what node your servers are on:
Log into the VPS control panel.
Select your VPS from the VPS list.
Check to see if your node field contains DC03R02DS36. If it does, your VPS will be affected by this maintenance.
For any other VPS you have with us, repeat steps 2 and 3.
If you have any questions, feel free to open a ticket. |
