Symptoms

Quando si verifica un backup del database MCS, è possibile che venga visualizzato il seguente errore:

errore <avtar 16507>: Percorso "var/mc/server_data/prefs/sessionticket.srl": Il totale dei byte elaborati #> non è coerente con la <dimensione <dei dati originale #
>
I backup successivi verranno completati senza problemi.

Cause

Questo errore viene visualizzato quando sessionticket.srl viene scritto durante il backup e le sue dimensioni cambiano.

Resolution

sessionticket.srl non è necessario per ripristinare MCS, pertanto questo errore può essere tranquillamente ignorato.  

Soluzione alternativa:
Se si desidera evitare questo errore in futuro, seguire la soluzione alternativa fornita di seguito per modificare il file di mcserver.xml Prima di apportare modifiche al mcserver.xml

crearne una copia di backup: 
cd /usr/local/avamar/var/mc/server_data/prefs/
cp -p mcserver.xml x-mcserver.xml.old.'date -I'

Edit /usr/local/avamar/var/mc/server_data/prefs/mcserver.xml and add the following information to the flush_exclude_subdirs line:

,prefs/sessionticket.srl

So the flush_exclude_subdirs line should appear as follows:
value="mcs_data_dump.sql.restore,postgres/data/base,postgres/data/global,postgres/data/pg_clog,postgres/data/pg_xlog,postgres/data/postmaster.pid,flush,postgres/data/pg_log,postgres/data/pg_tblspc,postgres/data/pg_twophase,postgres/data/pg_multixact,postgres/data/pg_subtrans,postgres/data/pg_stat_tmp,prefs/sessionticket.srl" />

Note that the MCS will need to be restarted for these changes to take affect:
 

dpnctl stop mcs
dpnctl start mcs

Once the next backup of the MCS has been completed you can confirm the sessionticket.srl was not backed up by grepping through the flush.log to confirm;

grep sessionticket.srl /usr/local/avamar/var/mc/server_log/flush.log
