Database corruption with MariaDB : Table doesn't exist in engine
I'm in an environement setup, running OSX with MariaDB 10.0.12-MariaDB Homebrew
I've screwed up the installation so I did completely removed MySQL and MariaDB from my setup and started again.
After finishing installing MariaDB, I've reimported my databases (innoDB) via a DB Dump from the production server. It worked fine.
After a reboot, the day after, I can no longer access to the databases :
Table 'my.table' doesn't exist in engine
What's causing this and what's the solution ? I do see the structure of my database, but when I try to access it, it gives me this error message.
I did try mysql-upgrade --force and deleting rm ib_logfile1 ib_logfile0
The data loss is not a problem here, the problem is that I can't spend 30 minutes on re-installing each database each time I do a reboot.
Here's some logs :

Answer
Something has deleted your ibdata1 file where InnoDB keeps the dictionary. Definitely it's not MySQL who does it.
