mysql 5.6 to mariadb 10.1.x centos 7.x datadir issue

I'm looking to upgrade/switch away from MySQL 5.6 in favor of MariaDB 10.1.x however, I received the following fatal error:

As of MariaDB 10.1.16, the data directory cannot reside in /home, /usr, /etc, /boot, or /root directories on systemd equipped systems. You must move your MySQL data directory outside of these directories before continuing with this upgrade.

I understand from a bit of research that this might be related to the default SELinux permissions but not exactly sure.

My question and issue is that my sql datadir is >170gb, and I don't have another partition other than /home to move it to. Is there anyway I can work around this, perhaps a symlink??

After a couple hours of googling I've hit a wall, surely someone else has encountered this, and was able to persevere?

Thanks in advance!

 

Hi Michael,

If mysql datadir is set to /home/mysql, could I just bind this to a different path via mount --bind? Optionally, I've read that setting ProtectHome=false in /usr/lib/systemd/system/mariadb.service could do the trick.

I've not tested either of these options in CPanel, but would you know if either of these methods would provide a stop-gap solution?

Thanks
