Quota Backup

[Norman Zhang <norman.zhang@xxxxxxxxxxxxxxxxxxxx>]

Hi,

I'm trying to use xfsdq/xfsrq to backup/restore the Quota of XFS 
partitions from one machine to another. However, the disk on the other 
machine is on a different host/bus/. Also the Samba users are of 
differnent uid. Can xfsdq/xfsrq do the job? Please help.
I tried,

# xfsdq -u xfshome /home  # on machine1
# xfsrq -u xfshome        # on machine2

but got the following error messages,
