Then mounted top-level volume on /mbt/temp. And then ran balance to convert to raid1.. When finished I umounted /mnt/temp (the top-level) and then my 3 subvolumes was unmounted and a cannot mount them at the same mountpoints again... No errors and it says that it is not mounted when trying to umount them. So it seems they don't get mounted at all and without throwing an error > > I will look into it more thoroughly now that I can at least mount the subvols on other mountpoints than the original Given those symptoms (mount doesn't report errors, but no mount happens), I would guess that your problem is with systemd. It has a bug where it sometimes unmounts things immediately after you've mounted them.
