I'm assuming you've used lvs to get logVol101 as an lv name.
Does df or mount (no arguments) show anything already at /mnt/d?
It looks like the lv may have an ext3 file system. The error is
complaining about the mount point. Try another one.

I've never heard of a file system called lvm2pv. To use such a system
you would need built-in kernel support or a loadable module.
cat /proc/filesystems and ls /proc/fs will give you some information
about what file systems the kernel knows about.
