Recently moved servers, the previous server had MariaDB 10.1 installed while the new server had 10.2.

Everything was okay until I restored a backup from the old server, and I got errors which I tried to fix, but I believe I have just made things worse. Now the problem is that we have gone live and I cannot restart MySQL because of the following errors (see attached file).

I contacted my hosting company and they have suggested that save my databases, and uninstall MariaDB and reinstall it again, as they believe that this will fix the issue. However, I am unsure how to do this or will I just make things worse :(

Any help would be appreciated, cheers.

InnoDB only wrote those files full of zeros, but did not yet use them in any way. But be careful: do not remove old data files which contain your precious data!
