Searching for this error message on the Internet shows some some results, although nothing seems to apply to my case. In any case apologies if I’m doing something really dumb.
I have a 3 node cluster running mysql+percona just fine (under docker containers). Then I do one of the following:
I (gracefully) terminate one of the nodes and then start it again.
I (gracefully) terminate one of the nodes, delete the grastate.dat and gvwstate.dat and then bring the node up again.
In case 1 I get:
Reversing history: 0 -> 0, this member has applied … more events than the primary component.Data loss is possible. Aborting.
and mysqld terminates. In case 2 I have no error messages and everything seems to work, but obviously this is not the way I should be doing it.
I would be very grateful if someone could give me any hint on what I could be doing wrong.
