So, what action can I do to pass this problem ??
How can I make a better alignment of these partitions ?

Rich,

Ah .. this does explain why the fstrim failed on every disk apart from /dev/sda.
My patches to implement fstrim in NTFS give up unless the partition is aligned
sufficiently:
http://comments.gmane.org/gmane.comp.file-systems.ntfs-3g.devel/1074
/dev/sda is sufficiently aligned, but the other 8 disks are not.
This is rather unfortunate for you because fstrim would undoubtedly have saved network
bandwidth as well as making qemu-img do less.
At least that mystery is solved.
Rich.
