Yepp -  I found my wrong track here. Will re-configure.

So true - wouldn't it make sense to make either fstab contain something 
like a spindle id to
find out about shared devices or to support a spindle id for disk 
devices via ioctl(). That
way fsck could find the non conflicting devices for unhindered parallel 
checks.
