Backport
This PR is auto-generated from #17087 to be assessed for backporting due to the inclusion of the label backport/1.5.x.
The below text is copied from the body of the original PR.
When the server restarts for the upgrade, it loads the
structs.Jobfrom the Raft snapshot/logs. The jobspec has long since been parsed, so none of the guards around the default value are in play. The empty field value forEnabledis the zero value, which is false.This doesn't impact any running allocation because we don't replace running allocations when either the client or server restart. But as soon as any allocation gets rescheduled (ex. you drain all your clients during upgrades), it'll be using the
structs.Jobthat the server has, which hasEnabled = false, and logs will not be collected.This changeset fixes the bug by adding a new field
Disabledwhich defaults to false (so that the zero value works), and deprecates the old field.Fixes #17076
