Current Series Release Notes¶
When nova_virtlogd container gets restarted the instance console auth files will not be reopened again by virtlogd. As a result either instances need to be restarted or live migrated to a different compute node to get new console logs messages logged again. Usually on receipt of SIGUSR1, virtlogd will re-exec() its binary, while maintaining all current logs and clients. This allows for live upgrades of the virtlogd service on non containerized environments where updates just by doing an RPM update. To reduce the likelihood in a containerized environment virtlogd should only be restarted on manual request, or on compute node reboot. It should not be restarted on a minor update without migration off instances. This introduces a nova_virtlogd_wrapper container and virtlogd wrapper script, to only restart virtlogd on either manual or compute node restart.
New hiera setting rbd_disk_cachemodes allows to override the disk cache modes for RBD. Defaults to [‘network=writeback’].
Added “scripts” parameters for class tripleo::profile::base::metrics::collectd::sensubility enabling download of various scripts for usage within sensubility check definitions. Supported transfer method is HTTP only currently.
