I've installed gentoo on my new computer, but i forgot to create my sub-volume __current and __snapshot.
Can i make it now and copy the file of / under it? I know i need to adjust fstab but is it the only thing what i need to do?

Thx for your answear and sorry for my bad english

yes, it should work. if you want to make sure you boot a rescue-system from usb or cd and copy/rsync the stuff. if the "old" dirs/files are still in place you can still boot the "old" system - it will not care if there is an additional __SUBVOL somwhere in /

don't forget to adjust the root-param in grub - or, better, create an additional on for the new system in the subvol and after that has booted and works correctly delete the old one
GOOD LUCK!
