ZFS and mv utility

[Alexey Tarasov]

Hello Pawel.

I have a question about ZFS and mv utility. I have the following pool  
configuration:

NAME                          USED  AVAIL  REFER  MOUNTPOINT
storage                      62,1G   121G    26K  /storage
storage/music                7,95G   121G  7,95G  /storage/music
storage/oldhome              47,5G   121G  47,5G  /storage/oldhome

I made the following operation: mv /storage/oldhome/lexa/music/* / 
storage/music and that operation took a very long time. It seems that  
MV copies files first from storage/oldhome/lexa/musc to storage/music  
and then deletes them from old location. But I move files within one  
storage pool and it should work as fast, as it works on UFS  
partition. Does it need to be modified for compatibility with ZFS?

Thanks,
