Update restbase100[1-6] to the 3.19 kernel
Closed, ResolvedPublic
Actions

Description

We're using a custom 3.19 kernel on top of Debian jessie. New installations are rolled out with the 3.19 kernel directly, but older systems need to be upgraded, which involves a reboot.

Roll-out plan, set for Tuesday, 2015-06-16, involving @MoritzMuehlenhoff and @mobrovac :

  • disable Puppet on all boxes
  • disable Cassandra and RESTBase on boot on all boxes
  • on each box, sequentially:
    • upgrade the kernel
    • stop RESTBase and Cassandra
    • restart and check the new kernel
    • bring Cassandra up and check joining
    • bring RESTBase up and check its operation
  • upon completion do another rolling restart of RESTBase to ensure all DB connections are up and alive

Lets wait with this until the new nodes (restbase1007-9) have finished bootstrapping. That should be done by mid / end next week.
