<PRE>Hi,
There are several problems today with mariadb, some more serious than
others:
Firstly, (a minor problem) the log file:
Jan 3 14:04:34 jimmy mysqld_safe[10642]: 120103 14:04:34 mysqld_safe
Logging to '/var/log/mysqld/mysqld.log'.
Jan 3 14:04:34 jimmy mysqld_safe[10642]: 120103 14:04:34 mysqld_safe
Starting mysqld daemon with databases from /var/lib/mysql
Jan 3 14:05:53 jimmy mysqld-prepare-db-dir[11245]: touch: cannot touch
`/var/log/mysqld.log': Permission denied
Jan 3 14:05:53 jimmy mysqld-prepare-db-dir[11245]: chown: cannot access
`/var/log/mysqld.log': No such file or directory
Jan 3 14:05:53 jimmy mysqld-prepare-db-dir[11245]: chmod: cannot access
`/var/log/mysqld.log': No such file or directory
As the script is run as the mysql user, it cannot touch the
(non-existant) log file as the directory is owned by root. Better to do
this in a %post script to ensure the file is all present and properly
owned to avoid this error.
Secondly, several plugins were moved to mariadb-obsolete. I have most of
my databases stored in innodb format and this was one of the plugins
moved over. Even when I did install the -obsolete package to get
ha_innodb back, I couldn't use it:
120106 10:15:02 Percona XtraDB (<A HREF="http://www.percona.com">http://www.percona.com</A>) 1.1.8-20.1
started; log sequence number 52870027141
120106 10:15:02 [ERROR] Function 'InnoDB' already exists
120106 10:15:02 [ERROR] Couldn't load plugin named 'InnoDB' with soname
'ha_innodb.so'.
Now I believe this is due to XtraDB duplicating the features of InnoDB
and thus effectively obsoleting it... does this mean I simply shouldn't
load InnoDB plugin now? Does it mean all the tweaks I made in my.cnf for
innodb pool sizes etc. now no longer work? What is the fallout from this
change?
Thirdly, federated was changed to fedaratedx, but federated was still
shipped in the mariadb-obsolete package... Sadly however the default
my.cnf still tries to load the ha_federated.so by default and activate
via a "federated" option in default my.cnf. So not only is a plugin
activated that is not installed, even when you do install
mariadb-obsolete, the "federated" option seems to no longer work anyway:
120106 10:14:16 [ERROR] /usr/sbin/mysqld: unknown option '--federated'
So the "federated" option and the plugin load itself in my.cnf needs to
be updated somehow, both in the default my.cnf but also some attempt
should be made to update existing my.cnf too (with a backup).
