Dear DRBD users,
this is the final release of drbd-reactor 0.4.0.
For details in this release please see RC1  and RC2 .
There have been some additions since the last release candidate for the
- The promote systemd template we ship with drbd-utils 9.18.0 uses
'ExecCondition' to switch the resource to Primary. This keyword is not
available on older systemd versions (e.g., current Proxmox stable),
and IMO 'ExecStart' is a better fit, so generate such an override.
- startup: the drbd-reactor.service file is now scheduled after
networking, so that it can bring up the DRBD resources successfully,
otherwise the IP for that host might not even exist and "drbdadm
- coordinated shutdown: as you might know by now the promoter plugin
starts systemd targets (drbd-services at .target). But on system shutdown
these might stop, which triggers drbd-reactor to start them again,
while it gets stopped,... This is now solved by generating a 'Before'
dependency in the target override.
With 0.4.0 released, DRBD promotion should be handled by drbd-reactor,
so please set the according option to disable auto-promote, as shown
here in the "HA LINSTOR Controller section" .
* ctl,promoter: improve active on
* promoter: compat with older systemd, make promotion a dependency
* start after network is online
* promoter: improve system shutdown
