hi,

i just inherited a mysql server 4.1 and need to run mysql_fix_privileges on it. However one of the databases hosted on it is production and I'd rather avoid it to be down.

I ran the script on an 4.0 server test that I had installed and which was running when I ran the script. I had no problem with it, and the server is still up without downtime.

I hope everything will be fine as well for the production server, but in case of how can I back up my data to revert if any problem?

If I do a dump of mysql database will it be enough?meaning if there is any problem during the execution of the script will it be enough to reload the mysql database?

I also had no problem with the old_passwords on my test db, shall I expect any problem with the clients who would like to connect after I run the script?

Last, one of the server on which I have no control (4.0.9-gamma) but that I have to use would need the update of the privileges tables as well: what are the consequences/risks in not running it?

Thanks for your help.
