Revision as of 07:45, 7 August 2015

No scheduled downtime is required because service is unaffected (accounting is affected).
Steps

Connect to dcip.pic.es (where the billing database resides)
Make a backup of the DB (or pick one from /DBbackups and save for future references). Bacula should be keeping track of this directory...
/etc/init.d/dcache httpd stop
/etc/init.d/postgresql stop
mv /var/lib/pgsql/data /var/lib/pgsql/data.toremove
/etc/init.d/postgresql initdb
Create srmdcache user / role:
su - postgres

createuser srmdcache # Answer yes

createdb -U srmdcache billing

exit
/etc/init.d/dcache httpd start

If everything looks as you like you can now remove the old db:

rm -rf /var/lib/pgsql/data.toremove
