[rt-users] MySQL backups of RT 4.4.1 truncated

Hello Stephen,

 

just a stab in the dark, but could you please check the value set for
“max_allowed_packet” in the mysqldump section of /etc/mysql/my.cnf (or
whatever your my.cnf file is named)? If you try to dump mysql objects that
are larger than this size, mysqldump will stop; probably with a message like
“mysql server has gone away”. You can raise that value for mysqldump just by
editing that file; no server restart is required. 

 

HTH,

Thomas Bätzler

I just ran a test with the attachments table “ignored”, and the backup
worked perfectly. As a “sanity check”, I also ran mysqlcheck on the schema &
no errors were found. Should I split my backup job into two pieces, or is
there a better way to get a backup all in one shot?

I'm currently running RT 4.4.1 on Ubuntu 14.04 LTS with MySQL 5.6 on Windows
Server 2012. Recently, we enabled full-text indexing in native MySQL &
everything is great. After doing some work on the server over the weekend, I
discovered that the .sql files being generated for the backup are being
"truncated" after the attachments table (~18-19GB).  After reviewing your
documentation (https://docs.bestpractical.com/rt/4.4.1/backups.html) I
realized my mysqldump command was incorrect. I'm working in a lab
environment now to see how I can optimize/change my script to more closely
match yours. The only thought I have right now is to exclude the data from
the AttachmentsIndex as that would get rebuilt on restoration anyways. Is
there any other reason that the backup would just "stop" after the
attachment table? I apologize if this is beyond the scope of the forums
thread.

 

Thank you in advance!
