Hi,

    When I use "xfs_quota -x -c 'report -u /dev/sde5'" to show
/dev/sde5's quotas, and the result have two same block as below:

What version of xfs_quota are you using? What is the output of
/proc/mounts and /etc/mtab say?
xfs_quota's version is 3.1.1 and output of /proc/mounts like this:

.....
/dev/sde3 /root/mnt_path xfs rw,relatime,attr2,usrquota 0 0
/dev/sde5 /root/mntpath2 xfs rw,relatime,attr2,usrquota 0 0
/dev/sde7 /root/mntpath3 xfs rw,relatime,attr2,usrquota 0 0

/etc/mtab:

....
/dev/sde3 /root/mnt_path xfs rw,uquota 0 0
/dev/sde5 /root/mntpath2 xfs rw,uquota 0 0
/dev/sde7 /root/mntpath3 xfs rw,uquota 0 0

in the original post "/dev/sde5" was removed and try "/dev/sde7", the remain the same problem.

And does the latest version of xfs_quota have the same problem?
version 3.1.8's output have the same problem,and even worse, there are three same blocks :
