Hmmm... does it matter that selinux support isn't activated in my kernel?
But to make it short: it turns out now that the problem disappears, when 
I use the "real" device of the logical volume (/dev/mapper/export-lvol0) 
in the mount command instead of the symbolic link /dev/export/lvol0 -> 

Is this a bug or a feature? Looks like a bug to me...
