Dear List Users,
I have mediawiki 1.29-Release running on FreeBSD-11.1-Release and have had a crash of my MySQL database. At first, I couldn't start it at all. But after deleting ib_logfile* and ibdata*, it came back alive. In the sense that I can start the server and use many of the databases. But not the one holding my mediawiki installation.
The error log says "[Warning] InnoDB: InnoDB: Cannot open table mediawiki_something_dk/user from the internal data dictionary of InnoDB though the .frm file for the table exists.." The debug log is quite full but has the message "Error: 1146 Table 'mediawiki_something_dk.l10n_cache' doesn't exist (localhost)"
Does anyone know how to solve this? Or maybe have somehere, I can look for a solution.
Best regards, Jon Theil Nielsen
If that is the only issue you can re-create the table (the exact command should be in an .sql file) that table doesn't contain critical info

Sorry to a silly question. But which file should i look for. And do i just import it into MySQL plain and simple?

Go ahead and stop Apache, and if you haven't already, make a disk copy of your mysql data directory for backups. Then start MySQL alone. See if you get any errors from starting MySQL (find logs at /var/log/mysql/error_log or similar). Post any errors. If the db server is running, do some checks on the mediawiki schema like mentioned here [1].

Thanks a lot for the thorough answer. I will follow your suggestions tomorrow. And I will report back under any circumstances. I have full root access, so I guess this could be the way to go.
Thanks again!

I'm not sure what sort of solution you're looking for. You deleted the InnoDB data file (ibdata*), and now it unsurprisingly says the InnoDB data file is gone. That file had your wiki in it, now it's gone.
If you have backups, we can talk about how to recover from them. Otherwise, DROP DATABASE mediawiki_something_dk; might possibly wipe those .frm files and put the database back into a consistent (empty) state. Not sure, I've never heard of anyone deleting ibdata file before. If it does work, then you can make a new empty wiki, if that is a useful thing for you.

"He" (me, "the OP") did that following some - maybe bad - advice found in another place. But I haven't used mediawiki for a while – so I do have backups from 2017-08-31 that should be okay. So what are your suggestions from here? Just copy (not move) it back an try if i works? Or there might be more clever approaches?

Hi Jon,
What version of MySQL are you using (5.7.?) If using the latest MySQL or MariaDB server, you'll have better performance and features. At 5.7.x, you've already got full-text searching in innodb tables.
As Jan Steinman pointed out, in general, always dump your data using mysqldump (as opposed to making backups by directly copying files in the data directory).
You should load your database dumps into a clean server environment. That means an empty data directory. If you've got sufficient backups (test them to make sure they are!), then you can rm -rf $my_data_dir/ But it's just as easy to setup a different path e.g. /var/lib/data_dir_new and configure that when starting a second MySQL instance. https://www.linux.com/learn/howto-reconfigure-mysql-use-innodbfilepertable-z... is an article that might give you a little perspective on running multiple instances of MySQL In short, just like Apache can listen on multiple ports besides just port 80; and can have multiple websites, each with their own document root, so too can MySQL run multiple servers simultaneously, on different ports, with different data directories and databases configured per server.
From the error messages, it looks like you restored the dump files into the
same MySQL server with pre-existing logs or binlogs. You may need to change the configuration of my.cnf to force recovery in that environment if that's all you've got. See https://dev.mysql.com/doc/refman/5.7/en/forcing-innodb-recovery.html I'm guessing that you might need to set it as high as 5 in order to be able to start the server and get new dumps. But you might not need this at all if you have dumps of all the existing databases and just use those to restore them to a _new_ server. You can re-use the same machine, just create a different environment for trying the restoration.

I'm not sure what sort of solution you're looking for. You deleted the InnoDB data file (ibdata*), and now it unsurprisingly says the InnoDB data file is gone. That file had your wiki in it, now it's gone.
If you have backups, we can talk about how to recover from them. Otherwise, DROP DATABASE mediawiki_something_dk; might possibly wipe those .frm files and put the database back into a consistent (empty) state. Not sure, I've never heard of anyone deleting ibdata file before. If it does work, then you can make a new empty wiki, if that is a useful thing for you.

Hi Greg,
Thanks again for a thoroug walk-through of my options. I have quite a few databases - not extremely many - so if the recovery option should work, that's tempting to begin with.
I might have mixed two editions of the /var/db/mysql by accident. So in the first place, I can remove that dir and copy back from the same backup. If that fails, I guess the best way to go is making the dumps/reimports. Or is this a bad strategy?

Hi Jon,
What version of MySQL are you using (5.7.?) If using the latest MySQL or MariaDB server, you'll have better performance and features. At 5.7.x, you've already got full-text searching in innodb tables.
As Jan Steinman pointed out, in general, always dump your data using mysqldump (as opposed to making backups by directly copying files in the data directory).
You should load your database dumps into a clean server environment. That means an empty data directory. If you've got sufficient backups (test them to make sure they are!), then you can rm -rf $my_data_dir/ But it's just as easy to setup a different path e.g. /var/lib/data_dir_new and configure that when starting a second MySQL instance.
https://www.linux.com/learn/howto-reconfigure-mysql-use-innodbfilepertable-z... is an article that might give you a little perspective on running multiple instances of MySQL In short, just like Apache can listen on multiple ports besides just port 80; and can have multiple websites, each with their own document root, so too can MySQL run multiple servers simultaneously, on different ports, with different data directories and databases configured per server.
From the error messages, it looks like you restored the dump files into the same MySQL server with pre-existing logs or binlogs. You may need to change the configuration of my.cnf to force recovery in that environment if that's all you've got. See https://dev.mysql.com/doc/refman/5.7/en/forcing-innodb-recovery.html I'm guessing that you might need to set it as high as 5 in order to be able to start the server and get new dumps. But you might not need this at all if you have dumps of all the existing databases and just use those to restore them to a _new_ server. You can re-use the same machine, just create a different environment for trying the restoration.

InnoDB data file (ibdata*), and now it unsurprisingly says the InnoDB data file is gone. That file had your wiki in it, now it's gone.
If you have backups, we can talk about how to recover from them. Otherwise, DROP DATABASE mediawiki_something_dk; might possibly wipe those .frm files and put the database back into a consistent (empty) state. Not sure, I've never heard of anyone deleting ibdata file before. If it does work, then you can make a new empty wiki, if that is a useful thing for you.

Hi Greg,
Have been away from this topic for some time, but it's still an actual problem.
Still in the category of stupid questions (I read the link at least): No problem to configure the old server as master if the steps are just to put
server-id = 1 log_bin = /var/log/mysql/mysql-bin.log expire_logs_days = 1 max_binlog_size = 100M
into my.cnf.
Are any special content I should throw into the configuration for the alternative my.cnf? And should the second server be started by mysqld_safe? Normally in FreeBSD, it is handled by the service script.
Best regards, Jon Theil Nielsen

Hi Jon,
What version of MySQL are you using (5.7.?) If using the latest MySQL or MariaDB server, you'll have better performance and features. At 5.7.x, you've already got full-text searching in innodb tables.
As Jan Steinman pointed out, in general, always dump your data using mysqldump (as opposed to making backups by directly copying files in the data directory).
You should load your database dumps into a clean server environment. That means an empty data directory. If you've got sufficient backups (test them to make sure they are!), then you can rm -rf $my_data_dir/ But it's just as easy to setup a different path e.g. /var/lib/data_dir_new and configure that when starting a second MySQL instance.
https://www.linux.com/learn/howto-reconfigure-mysql-use-innodbfilepertable-z... is an article that might give you a little perspective on running multiple instances of MySQL In short, just like Apache can listen on multiple ports besides just port 80; and can have multiple websites, each with their own document root, so too can MySQL run multiple servers simultaneously, on different ports, with different data directories and databases configured per server.
From the error messages, it looks like you restored the dump files into the same MySQL server with pre-existing logs or binlogs. You may need to change the configuration of my.cnf to force recovery in that environment if that's all you've got. See https://dev.mysql.com/doc/refman/5.7/en/forcing-innodb-recovery.html I'm guessing that you might need to set it as high as 5 in order to be able to start the server and get new dumps. But you might not need this at all if you have dumps of all the existing databases and just use those to restore them to a _new_ server. You can re-use the same machine, just create a different environment for trying the restoration.

Hi List
I am still struggling with the same issues.
On FreeBSD 11.1, I cannot start the mysql server normally. I have to set innodb_force_recovery to a value of 6 to get it started. And then it is of course in read-only mode.
As I understand from previous answers, I should use mysqldump on the mediawiki database, start mysql in a clean environment (alternative port, alternative database directory) and then restore the dump from there. Is this the right approach? I am not quite sure how to make server run in the mentioned clean environment since the startup is normally handled by a standard script and a reasonable my.cnf.
Output of ps aux | grep mysql:
1. /usr/local/libexec/mysqld --defaults-extra-file=/usr/local/etc/mysql/my.cnf --basedir=/usr/local --datadir=/var/db/mysql 2. /bin/sh /usr/local/bin/mysqld_safe --defaults-extra-file=/usr/local/etc/mysql/my.cnf --basedir=/usr/local --datadir=/var/db/mysql
Should I create a modified my.cnf with a different listening port - and not define basedir nor datadir - and the start the server with the same commands?
Best regards, Jon Theil Nielsen
