I am pleased to announce the latest maintenance release of
Corosync-Qdevice 3.0.1 available immediately from GitHub at
https://github.com/corosync/corosync-qdevice/releases as
corosync-qdevice-3.0.1.
This release contains important bug fixes and some of new features. Most
notable ones:
- Rewrite of DPD (dead-peer-detection) timer. Previously dead peer
detection was implemented sub-optimally and may result in QNetd waiting
too long before marking Qdevice peer dead and selecting new quorate
partition what made Qdevice not responsible for corosync votequorum
service resulting in lost of quorum. New implementation is using smaller
timeouts and no sampling (global DPD timer) so QNetd detects dead peer
long time before sync_timeout. Configuration option dpd_interval is
removed (no longer needed) and replaced by dpd_interval_coefficient (see
corosync-qnetd(8) for more details). This fixes GH issue #10.
- Implement KAP Tie-breaker (keep active partition) for ffsplit
algorithm. This solves problem when Corosync creates single node
partition during startup and for two node clusters with ffsplit this new
node might get vote eventho there was already other quorate node. This
option is enabled by default. To use previous behavior it's possible to
set keep_active_partition_tie_breaker in corosync.conf (see
corosync-qdevice(8) for more details). Fix for GH issue #7.
- Qdevice systemd unit file now restarts on-failure.
- Configurations without ring0_addr are now properly supported. Fixes GH
issue #16.
