Re: Setup a replication slave without stopping master

We get asked to do this a lot :) There's a bunch of different cases.
What storage engines are you using? Do you have LVM with free space
on the volume group, or another way to take snapshots such as a SAN?
Sometimes there are clever ways to get around various limitations, but
I'll wait till you reply because there are too many different
permutations to just write about all of them.
