Well ... now, some say write to zero, me saying reserve a little, others say reserve more ... :D

Another interesting possibility. Maybe even better than applying a quota.
I always wanted to try this out ... once I tried it and it was not that flexible as described everywhere, but can not remember the details (I may find the server with this setup though ... maybe I should have a look at it)

Yeah I know, over the years I had a couple of hard issues with mysql, resulting from full disks, failed disks, etc.
But - as far as I can remember - the tables always could be repaired! Manual intervention was required, but it worked. And its been some time since the last accident of that type happened, so maybe they got better ... lately bitchy replication ranks up on my most annoying issues, but we leave the topic...
