Kernel Updates
|
||||||
|
--------------
|
||||||
|
|
||||||
|
If the kernel has been updated, you will probably want to reboot the hosts to
|
||||||
|
boot into the new kernel. This can be done using a command such as the
|
||||||
|
following::
|
||||||
|
|
||||||
|
(kayobe) $ kayobe overcloud host command run --command "shutdown -r" --become
|
||||||
|
|
||||||
|
It is normally best to apply this to control plane hosts in batches to avoid
|
||||||
|
clustered services from losing quorum. This can be achieved using the
|
||||||
|
``--limit`` argument, and ensuring services are fully up after rebooting before
|
||||||
|
proceeding with the next batch.
