Symptoms

Checkpoint non riuscito con risultato "MSG_ERR_BADTIMESYNC".

Il "avmaint cpstatusIl comando " mostra il seguente errore:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>

Il "mapall --parallel 'date'" mostra che un nodo non è sincronizzato:

Verifica del protocollo NTP (Network Time Protocol) con "ntpq -pn" mostra il messaggio "Connessione rifiutata" sul nodo
sospetto (output modificato per mostrare solo il nodo interessato)

admin@utility:~/>: mapall --noerror '/usr/sbin/ntpq -pn'
Using /usr/local/avamar/var/probe.xml
...
(0.3) ssh -q  -x  -o GSSAPIAuthentication=no admin@192.168.255.5 '/usr/sbin/ntpq -pn'
/usr/sbin/ntpq: read: Connection refused
...
 

Quando si verifica lo stato direttamente come root sul nodo interessato, il "Network Time Protocol Daemon" (NTPD) mostra "Active: activating (auto-restart) (Result: resources)":

root@node03:~/>: systemctl status ntpd
● ntpd.service - NTP Server Daemon
   Loaded: loaded (/usr/lib/systemd/system/ntpd.service; enabled; vendor preset: disabled)
  Drop-In: /run/systemd/generator/ntpd.service.d
           └─50-insserv.conf-$time.conf
   Active: activating (auto-restart) (Result: resources) since Fri 2022-09-23 13:22:35 UTC; 1min 58s ago
 

Lo stato deve essere Active: active (running):

● ntpd.service - NTP Server Daemon
   Loaded: loaded (/usr/lib/systemd/system/ntpd.service; enabled; vendor preset: disabled)
  Drop-In: /run/systemd/generator/ntpd.service.d
           └─50-insserv.conf-$time.conf
   Active: active (running) since Fri 2022-09-23 14:04:37 UTC; 26s ago
 

Il tentativo di avviare NTPD non riesce:

root@node03:~/#: systemctl start ntpd.service
Job for ntpd.service failed because a configured resource limit was exceeded. See "systemctl status ntpd.service" and "journalctl -xe" for details.
 

L'output di "journalctl -xe" segnala i messaggi "No space left on the device".

Il "df" mostra che /var è al 100%:

Cause

NTPD si basa su /var/lib/ntp/drift/ntp.drift che contiene la stima più recente dell'errore di frequenza di clock.

se /var è pieno al 100%, NTPD non può aggiornare o creare il ntp.drift e NTP non funziona correttamente.

Resolution

1. Sul nodo interessato, analizzare e risolvere l'utilizzo al 100% di /vaR.

2. Una volta corretto:

Un. Riavviare NTPD: 

root@node03:~/#: systemctl restart ntpd
Nota: Un riavvio riuscito non genera alcun output.
 
 

B. Controllare lo stato di ntpd:

root@node03:~/#: systemctl status ntpd
 

Dovrebbero essere visualizzati risultati simili ai seguenti:

c. Verificare NTP con ntpq:

root@node03:~/#: /usr/sbin/ntpq -pn
 

Dovrebbero essere visualizzati risultati simili ai seguenti:


     remote           refid      st t when poll reach   delay   offset  jitter

3. Confermare la risoluzione eseguendo un checkpoint manuale da Avamar Utility Node.
