FOG 1.5.7 Update Database Issue

chaonatic

On Ubuntu 18.04.2, when upgrading FOG from 1.5.6 to 1.5.7, I get the following error:

 * Installing package: mariadb-client..........................Failed! (Will try later)

Then the install hangs for quite some time here:

 * Setting up and starting MySQL........................

When the installer asks to hit the web interface to setup the database schema we are just left with the “Database connection unavailable” dialogue.

I’m not sure what’s amiss here so any direction would be totally welcome. Thanks!

mariadb-client

If I remember right (I should look it up), but I think the repo changed the case of the package to something like MariaDB-Client as well as for the server.

Edit: I found the post I was thinking about, but its related to centos and not ubuntu: https://forums.fogproject.org/topic/13470/cannot-upgrade-fog-1-5-4-to-1-5-6-maria-db-issue

From the fog server linux command prompt what do you get when you key in sudo apt-get install mariadb-client?

Sebastian Roth

@chaonatic Manually edit /opt/fog/.fogproject and change the line starting with packages=.... Make the parts with “mariadb…” to read like this: MariaDB-client MariaDB-server (yeah, upper case M …)

If that doesn’t work we need the installer log that you find in the same directory where you run the installer - e.g. fogproject/bin/error_logs/...!

I don’t see the .fogproject file, only .fogsettings. I did attempt to change the two database entries in the settings file from mysql-client and mysql-server (note that they were generically named) to MariaDB-client and MariaDB-server but I got the same installation results. To be clear, I need to modify these entries prior to installing the update, right?

@chaonatic Ok, obviously I was totally on the wrong track. So you seem to have a different situation than what we saw in the other topic.

mariadb-client : Depends: mariadb-client-10.1 (>= 1:10.1.40-0ubuntu0.18.04.1) but it is not going to be installed

This error message is pretty interesting. I see that there are indeed two packages in Ubuntu one mariadb-client and one mariadb-client-10.1 - both the exact same version 10.1.40-0ubuntu0.18.04.1.

Doesn’t make sense to me. What happens if you run sudo apt-get install mariadb-client-10.1??

As well try sudo apt-get -f install - post output here.

@chaonatic Well that might have fixed it. But I am still not sure how you got into this situation or if this is something every Ubuntu user will face sooner or later?! As far as I know we have not seen this issue in the forums before.

So now I’d suggest you run sudo apt-get install mariadb-server-10.1, then change the packages=.... line in /opt/fog/.fogsettings (got the name wrong last time) back to mariadb-client mariadb-server and re-run the FOG installer script.

Keeping my fingers crossed this is not something we’ll see on every Ubuntu update now. Still can’t really see what’s going on here and why this is happening.

chaonatic

@Sebastian-Roth Well we’re definitely closer. The installer doesn’t fail when installing the databases but when you get to updating the database I’m still getting the Database connection unavailable error. Is this something to do with the blank vs not blank password (I mean, I’ve not yet set a DB pass)?

Sebastian Roth

@chaonatic Try to manually connect to the DB and see if that works: mysql -u root -p (just hit ENTER when it asks for a password if yours is empty)

My apologies if this ends up as a duplicate post, tried to register and the confirmation email wasn’t getting through the work address… anyways

I’ve got the same issue: Running 1.5.6, trying to upgrade to 1.5.7 on Ubuntu 18.04.2.

Just tried manually installing the appropriate mariadb packages ( -common, -client and -server)

Here’s the problem:

Looks like the script isn’t set up to handle the migration from mysql 5.7 to mariadb given the exception that the package manager throws so it scraps the existing install.

Not sure what avenue you want to take with the script, but it looks like it’s going to break any existing ubuntu installs that are trying to go from mysql to mariadb.

Ping me if you need any more info, I’ll post back if if make any headway on my install.

notverypunny

So for anyone else running into this, or if the devs want to make this work in the script, here’s what I had to do to get this upgrade to work:

backup fog db
perform manual install of mariadb-common, mariadb-server and mariadb-client
reboot (services wouldn’t start and play nice, this was the simplest thing, should also be possible without restarting but I didn’t go there)
manually create fog db
restore fog db from backup
git pull and run bin/installfog.sh

knock wood things are now working as expected and the web interface seems snappier (could just be in my head).

Cheers

notverypunny

Aaand it looks like the same bug is present when updating storage nodes…

Similar process as far as a workaround goes, but without the backup and restore of the fog db as it isn’t part of the storage node.

Sebastian Roth

@notverypunny Really great you managed to work your way out of this. We had one other user some days ago who ran into the same issue - see here.

Not exactly true. Only if you move from a MySQL version 5.7 and earlier up to a newer version - I guess even if you update from MySQL 5.7 to 5.8 you’d run into this on any Ubuntu installation. Can you please let us know which version of Ubuntu you had before going to 18.04.2??

EDIT: Sorry, I was under the impression that Ubuntu 18.04 did use MySQL later than 5.7 already. I was wrong! Just figured that it was me who caused this in the first place when I added Debian 10 support! https://github.com/FOGProject/fogproject/commit/fddac44877ebabbf6f01d38d39361179bc6ec04d

Probably the only thing we can do within the installer is check if MySQL 5.7 is installed and tell people to manually follow the steps outlined. I would not fancy doing this in an automated way within the installer scripts.

@Sebastian-Roth

With 18.04 being a LTS, I expect that they’ll keep mysql alive and well in their repos, or provide migration / upgrade within the distro’s framework. As such, the project’s (fogproject that is) best track might be to keep existing 18.04 installs on mysql unless there’s a compelling reason to force the migration.

I’m lucky that my fog servers aren’t hosting anything else, but migrating databases if someone has other workloads on the same servers might not be a simple task.

You are absolutely right here. I just setup a test environment and confirmed the commit posted below is actually causing the issue. Shouldn’t have done that in the first place. I’d happily revert that change back to what it was. But that would mean that you and some others will be reverted back to MySQL 5.7 on the next FOG release again. Very ugly I suppose. I will try to do some testing on what happens when I do this.

Sebastian Roth

@notverypunny In a test setup I was able to revert back to mysql 5.7 without much trouble. It seems to be able to use the database that mariadb used as well. The only issue I see is that the systemd service files seemed corrupted on my test system:

ls -lah /etc/systemd/system/ | grep -e maria -e mysql
lrwxrwxrwx  1 root root   35 Jul 22 20:10 mysqld.service -> /lib/systemd/system/mariadb.service
lrwxrwxrwx  1 root root   27 Jul 22 21:16 mysql.service -> /lib/systemd/system/mariadb

So I am still wondering if it’s a good idea to simply revert the change back to mysql-client mysql-server or if I need to add a check and if someone is on MariaDB already I just leave it alone?!?

I would add a check, assuming that the logic isn’t too much to code. MariaDB is the better db at this point from what I can see and I should think that most people would prefer it, especially on a new install.

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.
