Symptoms

Följande fel kan visas när en säkerhetskopia av MCS-databasen görs:

avtar Error <16507>: Sökväg "var/mc/server_data/prefs/sessionticket.srl": Det totala antalet bearbetade byte <#> stämmer inte överens med den ursprungliga datastorleken <#>

Efterföljande säkerhetskopieringar slutförs utan problem.

Cause

Det här felet uppstår när sessionticket.srl skrivs till under säkerhetskopieringen och ändrar storlek.

Resolution

sessionticket.srl krävs inte för att återställa MCS så det här felet kan ignoreras på ett säkert sätt.  

Lösning:
Om du vill förhindra det här felet i framtiden följer du lösningen nedan för att ändra mcserver.xml-filen

Innan du gör några ändringar i mcserver.xml gör du en säkerhetskopia av den: 
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
