[debian-mysql] Bug#507551: mysql-server-5.0: 'stop slave' would be nice when upgrading

[Jörgen Hägg]

Package: mysql-server-5.0
Version: 5.0.51a-18
Severity: normal

ERROR 1201 (HY000): Could not initialize master info structure

This could also be treated as a wishlist request, but the database
replication stops completely at a upgrade.
After this it is necessary to do a 'reset slave' and 'change master ...'
to get the replication up again.
(And of course first saving the current log_pos... :-)

This happened on two slaves, exactly the same behaviour.

I managed, however, to do an upgrade without reset by just
doing 'stop slave' before upgrade. It started again automatically
without any problem.

So I guess that something in the upgrade messes with the
relay logs, thereby causing the problem. (Sorry, lost the complete
error message.)
