FOG 1.5.7 Update Database Issue

FlangeMonkey

Did you guys find a fix for this? I’ve just upgraded from 1.5.6 to 1.5.7 and the MariaDB service won’t start.

Thanks,

Sebastian Roth

@FlangeMonkey When releasing 1.5.7 we did not expect this to be an issue but it turned out that moving from MySQL 5.7 to MariaDB is not yet properly supported by Ubuntu. It doesn’t do a merge of the DB over to the new version but simply shuts down the old MySQL DB (usually find that in /var/lib/mysql-5.7/) and creates a fresh empty new one for MariaDB.

and the MariaDB service won’t start.

While this sounds a bit different I can still imagine this being a similar case. Please run sudo systemstl status mariadb and post output here. As well run ls -al /var/lib | grep mysql and post here.

For all other users on Ubuntu out there. Please if you intend to update, use the current developer release 1.5.7.2 instead of plain 1.5.7 or wait till the next release is out. I just pushed out a fix that should address this current issue.

I am able to get into MariaDB with mysql -u root -p

Update, just refreshed the page and loaded into this

clicked Install/update now and can now see the dashboard, looks very empty. I will look more into this tomorrow

@Arrowtron Sorry to hear you have run into this as well. Unfortunately upgrading to 1.5.7.2 doesn’t help when you have gone to 1.5.7 already. We don’t do this as an automatic fix in the scripts as I find it too error prone to do in a scripted kind of way.

You should still have your “old” and valid database in /var/lib/mysql-5.7. Please follow the steps outlined below and I hope you should be right back up again:

sudo -i
mv /var/lib/mysql /var/lib/mysql-mariadb
apt-get remove mariadb-client mariadb-server
cp -a /var/lib/mysql-5.7 /var/lib/mysql
apt-get install mysql-client mysql-server
systemctl start mysql

/var/lib/mysql

Thanks for the reply,

I get this when i run the command
apt-get install mysql-client mysql-server

There is a MySQL server running, but we failed in our attempts to stop it.
Stop it yourself and try again!

Tried a few commands found doing a web search that didn’t help
apt --fix-broken install

You might want to run 'apt --fix-broken install' to correct these.

E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).

accidentally ran command sudo rm -rvf /var/lib
(thought i was typing in a new line, working too quick, was backing up mysql and purging etc) Going to start a fresh i think

Did you run apt-get remove mariadb-client mariadb-server before that? Kind of strange but you might have to kill the old DB process like this killall -9 mysqld…

=Update=
accidentally ran command sudo rm -rvf /var/lib

I am sure you have a backup of that machine! Do you? Just recover that directory from your backup and proceed.

Run apt --fix-broken install as suggested in the output and post what you get from this.

Arrowtron

@Sebastian-Roth

Yes i ran

apt-get remove mariadb-client mariadb-server

Didn’t try this command, it might have helped for the unmet dependencies problem

killall -9 mysqld

Yes i have some SQL backup’s from previous upgrade which I have restored onto a new server (just had to change IP’s etc which is fine)
It’s on a virtual machine where as physical before, snapshots will come in handy for next time!

Yes ran the apt --fix broken install and got the unmet dependencies for mysql errors. Didn’t have the time to keep looking into it

All goods, thanks for your help though!

Sebastian Roth

@Arrowtron I am sure you know about there being various places in files and the DB where you have to change the IP address: https://wiki.fogproject.org/wiki/index.php/Change_FOG_Server_IP_Address

@Sebastian-Roth

Yes found this Wiki when I was migrating, thank you
