Cause

Przyczyna jest nieznana, jednak poniżej przedstawiono potencjalne obejście problemu.

Resolution

1. Zaloguj się do węzła Avamar Utility Node jako „admin”.

2. Podnieś poziom uprawnień do uprawnień root.

3. Zmień nazwę pliku binarnego /usr/local/avamar/var/rabbitmq/mnesia katalog:

mv /usr/local/avamar/var/rabbitmq/mnesia /usr/local/avamar/var/rabbitmq/mnesia.`date +%y%m%d`
 

4. Ponowne uruchomienie rabbitmq:

service rabbitmq-server start
 

5. Sprawdź, czy /usr/local/avamar/var/rabbitmq/mnesia katalog istnieje:

ls -ld /usr/local/avamar/var/rabbitmq/mnesia*
 

Przykładowe dane wyjściowe:

drwxr-x--- 4 rabbitmq rabbitmq 97 Jul 21 19:46 /usr/local/avamar/var/rabbitmq/mnesia
drwxr-xr-x 4 rabbitmq rabbitmq 97 Jan 22 16:30 /usr/local/avamar/var/rabbitmq/mnesia.250721
 

6. Uruchom ponownie MCS na Avamar: Ponowne uruchamianie serwera konsoli zarządzającej.
