Dan at CERN noticed that his performance was tanking because updatedb was running against /var/lib/ceph. updatedb has a PRUNE line in /etc/updatedb.conf that we should presumably be adding ourselves to. One user pointed out a package that uses sed to rewrite this line in the init script on start. I have two questions: - is there no better way than sed to add ourselves to this list? - should we do it in the init script, or postinst, or both?
Well, I don't have a clue. postinst seems very dirty to me. It's a bummer that updatedb doesn't support a .d directory for configuration.
Presumably this is a problem others have solved with other packages. http://tracker.ceph.com/issues/7451
Not completely the same, but I filed something similar at Ubuntu yesterday: https://bugs.launchpad.net/ubuntu/+source/mlocate/+bug/1281074
It's to prevent Ceph clients from indexing CephFS or Ceph Fuse. Hopefully that makes it into 14.04.
