Hi,

The problem is that the original file system (ext4) has no inode 
available and increasing the size of an ext4 file system does not 
increase the number of the inode. To have no more inode problem the new 
filesystem is xfs, so I can not copy data with dd.

I stopped copying, deleted the two logical volumes and created a large 
logical volume that is formatted to xfs for backuppc. I keep four old 
drives for possible recoveries...  :o)
