Avamar 19.7: PDM mislykkes med 404-fejl efter opgradering, preferences.dtd er forkerte

Efter opgradering til 19.7 mislykkes PDM med:

Error while fetching tasks. Failed with HTTP error code: 404 additional information
HTTP Status 404 - Not Found.

Denne fejl kan være forbundet med forkerte tilladelser til filen:

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

Bekræft problemet ved at kontrollere connectionmanger.log og deploymanager.log

Connectionmanager.log er vist nedenfor.

1. På Avamar som root skal du kontrollere filtilladelserne:

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

Resultatet ser sådan ud:

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

2. Skift tilladelserne for preferences.dtd.

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

Filtilladelserne ser nu sådan ud:

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

3: Sørg for, at der ikke kører nogen sikkerhedskopier, og genstart derefter tomcat-tjenesten:

emwebapp.sh --restart

Proxy Deployment Manager kan nu bruges til at geninstallere proxyer.
Hvis proxyerne ikke blev implementeret for nylig, vil der ikke være nogen mulighed for at opgradere dem i PDM.
Installer dem manuelt, og slet de gamle proxyer.
