MariaDB won't start

Troubleshooting

Hi,

After updating to v6.25.3 (I think) mariaDB won’t start:

systemctl status mariadb

/var/log/mysql/error.log

is empty…

Is it related to this topic? https://dietpi.com/forum/t/nextcloud-breaks-mariadb-on-install/3329/1 (I don’t have next cloud installed)

What could be the problem?

2

What’s the location of your /dietpi/userdata folder?

3

I used Dietpi’s Drive Manager to move to a USB SSD. Could this be the problem and how to fix this?

4

Probably not but have a look at this anyway:

https://dietpi.com/forum/t/solved-new-install-6-22-odroid-xu4-mariadb-error/3107/4

Are there any clues in the log?

Hi,

Thanks for helping out, but your solution did not fix it.

There is nothing in /var/log/mysql/error.log, is there somewhere else a working log?

I remembered that I had also a full disk. I found this: https://help.nextcloud.com/t/100-disk-mariadb-wont-start-again/28697 also it didn’t want to start…

Sorry stumped here. I’ve had this happen numerous times for different reasons and always eventually fixed it. I take it you’ve uninstalled and reinstalled and looked in the MySql/MariaDB forums?

I did not uninstall/reinstall because I am afraid I lose my DB’s; I was hoping for a “easier” fix. As you have seen in my earlier posts in this topic; I did search around, but it’s hard to find the solution as I can’t find any logs of mariadb and also “systemctl status mariadb” doesn’t throw a detailed error…

You can use dietpi-backup before uninstall/reinstall.

I have uninstalled/renistalled MariaDB/MySql many times and haven’t lost my DBs but always good to have a backup.

It was just that: a stress bended usb cable to my SSD drive. Just gave it some slack and it works as a charm.

johnvick thanks for your help
