@Riledup5, if you've got H2S, immediate treatment is required. While H2S is volatile and can dissipate on its own, its presence in wine can produce other chemicals that will ruin the wine.
As suggested, the initial treatment is vigorous stirring and the addition of more K-meta. Yeah, it sounds odd adding sulfur to treat sulfur, but the compounds are totally different.
If this solves your problem? Great!
I encountered H2S a few months back, and here is that discussion. In my case, I could smell a small amount of H2S after initial treatment, so I added a product called Reduless, which is specifically formulated to treat H2S. Then I added kieselsol/chitosan to precipitate the results (along with all other suspended particles).
The old way was to pour the wine over clean copper pennies or an usused copper scrubby. However, the amount of copper introduced cannot be measured, and too much copper is poisonous. Using a measured amount of a product designed for removing H2S is strongly recommended.

Regarding head space in the carboy, if you have active fermentation, the wine is throwing off enough CO2 to displace all lighter gases, including O2. As you apparently discovered, filling the carboy too much will give you your very own volcano! I typically rack kits, whites, and fruits between 1.010 and 1.000, and leave ~6" headspace in the carboy until fermentation completes.
