A galera node went down and started reporting error innodb as unknown or unsupported engine

266 views Asked by At

One of my node was down and it was also the donor for the node A, so from node A config I removed the down node as donor. This is so that node A should not have to wait for the node to come up.

As the node that originally went down was on slow storage and slow network connection I decided to remove it. As I removed it and restarted the cluster even the node A didn't come up, on restart it started reporting error:

Why it started reporting Unknown/unsupported storage engine innodb now when it was working all this time?

Incidentally, I used another third node to bootstrap (start Galera_new_cluster).
