Filesystem is full error on first startup of MySQL

Help Section
1

Hello,

I have run into an error /: write failed, filesystem is full when starting MySQL80
I may be over my head here, but I thought I would post in case there is an easy fix I’m overlooking or maybe useful info for the devs?

I’m new BSD in general, so I’m trying out NomadBSD with the goal of using Nomad to turn an old Dell Optiplex 755 into a server using NextCloud on a FAMP stack.

I ran into a similar error using Nomad1.3 when installing Apache and saw that issue was addressed in 1.4-RC1, so that is what I’m running now.

The error is below along with before and after output of du
Thanks

Hi @Splined,

there is very little space on /, so you need to move mysql's directory, and create a symlink:

# mv /var/db/mysql /data/var/db/
# ln -s /data/var/db/mysql /var/db/
3

Yes, that did the trick. For some reason I thought the entire /var/db directory was moved under /data in 1.4, instead of a select few sub-directories. And I could have sworn I double checked that that was the case, oh well.

Thanks very much for your help. Everything else installed with no issues.

This will be the case in 1.4 :slight_smile:
