Ocfs2 users - Apr 2008 - Device or resource busy while mounting...

I have an OCFS2 filesystem that I'm trying to move from one set of servers
to another.  The filesystem is on a SAN, and I've recently set up a new set
of servers that I'd like to access the filesystem.  Unfortunately, this
doesn't seem to be working - I get the following:

xen02:~ # mount.ocfs2 -vv /dev/sdd1 /xenstore/vmdevel/ 
device=/dev/sdd1 
mount.ocfs2: Device or resource busy while mounting /dev/sdd1 on
/xenstore/vmdevel/. Check 'dmesg' for more information on this error.

...and there's nothing useful in the dmesg output to indicate why the device
or resource is busy.  Can anyone shed any light on this or offer any advice for
how to migrate an OCFS2 volume from one cluster to another?

Thanks, 
Nick

The errors indicates that either the source or the target is busy.
As in, device is already mounted or target has another mount
and has open files, etc. Check that first.

I found this happens to me when the mountpoint doesn't exist. Check to 
make sure /xenstore/vmdevel exists.
