I need to migrate Bacula from PGSQL 8.3 as it's being EOL'ed. The newest
version of PGSQL available in the FreeBSD ports tree is 9.2. Below are the
steps I've taken to describe the migration process:
########################################################
Backup PGSQL config file(s)
/home/pgsql/pg_hba.conf
/home/pgsql/postgresql.conf
Backup Bacula config file(s)
/usr/local/etc/bacula-dir.conf
/usr/local/etc/bacula-fd.conf
/usr/local/etc/bacula-sd.conf
/usr/local/etc/bconsole.conf
Dump PGSQL Bacula DB
/usr/local/bin/pg_dump bacula -v /home/bacula.sql
Rename PG data directory
mv /home/pgsql /home/pgsql.old
Stop PGSQL & Bacula processes
/usr/local/etc/rc.d/z-bacula.sh stop
/usr/local/etc/rc.d/postgresql stop
Uninstall Bacula Server & Client and any other Bacula package
cd /usr/ports/sysutils/bacula-server && make deinstall clean
cd /usr/ports/sysutils/bacula-client && make deinstall clean
Uninstall Postgresql 8.3 Server & Client
cd /usr/ports/databases/postgresql83-server && make deinstall clean
cd /usr/ports/databases/postgresql83-client && make deinstall clean
Install Postgresql 9.2
Install /usr/ports/databases/postgresql92-server
Install /usr/ports/databases/postgresql92-client
Initialize PGSQL db
initdb -D /usr/local/pgsql/data
if this gives you an error message
stop pgsql then 'rm -rf /home/pgsql/data'
start pgsql
then 'initdb -D /home/pgsql/data' - should work this time
Install Bacula
cd /usr/ports/sysutils/bacula-server && make install clean
cd /usr/ports/sysutils/bacula-client && make install clean
Restore PGSQL config files
/home/pgsql/pg_hba.conf
/home/pgsql/postgresql.conf
Restore Bacula config files
/usr/local/etc/bacula-dir.conf
/usr/local/etc/bacula-fd.conf
/usr/local/etc/bacula-sd.conf
/usr/local/etc/bconsole.conf
Configure Bacula as follows:
make pgsql member of bacula group
su pgsql
/usr/local/share/bacula/create_bacula_database
/usr/local/share/bacula/make_bacula_tables
/usr/local/share/bacula/grant_bacula_privileges
psql bacula < bacula.sql
If cannot retrieve bacula.sql file for some reason, can
restore from the most recent tape as follows:
bextract <exact volume name of catalog> ('man bextract' for
more details)
start pgsql
start bacula
remove pgsql as member of bacula group
Test
start bconsole and verify status of director
start a simple backup job and verify
########################################################
Questions:
1) Do I actually need to remove the bacula packages?
2) Are there any special steps that I'm missing when configuring the bacula
databases? Do I need to run 'update-bacula-tables' somewhere in there?
3) Is PGSQL 9.2 considered stable? 9.1 had some serious bugs but these appeared
to have been squashed.
4) Are there any special parameters I need to consider when going from PGSQL
8.3 to 9.2 especially in the postgresql.conf?
5) Any other caveats?
6) pg_upgrade: I came across this new function. Apparently you can upgrade
databases from 8.3.x to 9.2.x with some caveats as described in the "
Limitations in Upgrading from PostgreSQL 8.3" section of this link
http://www.postgresql.org/docs/9.2/static/pgupgrade.html. If you've used this,
would you care to share your experiences?
Thanks in advance.
