TMA-CASSANDRA-1.6
Ensure clocks are synchronized on all nodes
OrtaDüzey 1Otomatikcassandra
Açıklama
Enabling Network Time Protocol (NTP), or some equivalent way, to keep clocks on all nodes in sync is critical. The benchmark rates this recommendation Manual; the automated check covers its objective pass criterion. Uses timedatectl (systemd); passes when the kernel clock is reported as NTP-synchronised by chronyd, ntpd or systemd-timesyncd. Compare offsets across nodes as well.
Nasıl denetlenir
Denetim yöntemi: Kabuk komutu
shell
out=$(timedatectl show -p NTPSynchronized --value 2>/dev/null) || exit 1; printf '%s\n' "$out"- Beklenen çıktı
yes
Nasıl düzeltilir
Düzeltme yöntemi: Kılavuz veya altyapı yaması
Install and enable chrony (or ntpd) on every node, pointing all nodes at the same time sources: systemctl enable --now chronyd.
