Resolution

1. Kontrollera filbehörigheterna på Avamar som root:

ls -ltrh /usr/local/avamar/var/mc/server_data/prefs/preferences.dtd

Resultatet ser ut så här:

-r-------- 1 admin admin 4.5K /usr/local/avamar/var/mc/server_data/prefs/preferences.dtd

2. Ändra behörigheterna för preferences.dtd.

chmod 444 /usr/local/avamar/var/mc/server_data/prefs/preferences.dtd

Filbehörigheterna ser nu ut så här:

 r--r--r-- 1 admin admin 4.5K /usr/local/avamar/var/mc/server_data/prefs/preferences.dtd

3: Kontrollera att inga säkerhetskopieringar körs och starta sedan om tomcat-tjänsten:

emwebapp.sh --restart


Proxy Deployment Manager kan nu användas för att distribuera proxyservrar på nytt.
Om proxyservrarna inte distribuerades nyligen, kommer det inte att finnas något alternativ att uppgradera dem i PDM.
Distribuera dem manuellt och ta bort de gamla proxyservrarna.
