Anyway to stop an optimize?
Hi,
Does anyone know if an optimize can be stopped once started?
Thanks

This is correct.
And there is no way I can think of optimize could just start on its own - somebody or something called it.

A restart during an optimize should not cause index corruption. The optimize only reads existing indexes, and the only writes are to indexes not yet in use. If it does not finish, those half-written indexes are junk to be cleaned up later.

I think in the past I've tried that, and it has restarted, although I will have to try it out (this time we were loath to stop it as we didn't want any index corruption issues).
A related question is, why did the optimize start? I thought it had to be explicitly started, but somehow it started optimzing on it's own.
Thanks again

If you restart the server, the optimize should stop and not restart, right?

Don't think so, at least not gracefully. You can always do partial optimize and do a few of them if you want to optimize in smaller steps.
