Mounting two devices on / should not harm the XFS filesystem in itself. I 
even think that also new files created from within the already running 
part of the live distribution should go to the initially mounted root 
filesystem (if the live distro creates new files in there at all). But I 
am not completely sure on that.

Anyway, there are two ways to check: xfs_check or xfs_repair -n

I do not know an answer to you second question. But when atime updates are 
enabled you usually have your first write pretty soon.

Ciao,
