Hi people,

I have a problem with my XFS filesystem. I don't know, where is the
problem. Look:

------------%<------------
0:00 root@Idea [/home/] ##: du -c -h -s /home/dir/
4.0T    /home/dir/
4.0T    total
------------%<------------

But this is not so big disk array. dir/ is on 19G /home partition:

---------------------------%<---------------------------
0:00 root@Idea [/home/] ##: df -h
Filesystem            Size  Used Avail Use% Mounted on
/dev/md1              4.9G  4.2G  705M  86% /
/dev/md0              2.0G  118M  1.9G   6% /tmp
/dev/md2              4.9G  3.8G  1.2G  77% /var
/dev/md4               12G  3.9G  7.4G  35% /backup
/dev/md6               35G  5.1G   30G  15% /share
/dev/md3               19G   15G  4.4G  77% /home
tmpfs                 976K  4.0K  972K   1% /dev/shm
---------------------------%<---------------------------

And disk quota of users:

-----------------------------------%<-----------------------------------
0:00 root@Idea [/home/vmail/talkive.com/info] ##: quota -v rajo
Disk quotas for user rajo (uid 1000): 
     Filesystem  blocks   quota   limit   grace   files   quota   limit   grace
       /dev/md0      84       0       0              20       0       0        
       /dev/md6 4551256       0       0           58708       0       0        
       /dev/md3 18014398501983224       0       0           77196       0       
0        
-----------------------------------%<-----------------------------------

It is possible to determine, where is the problem? I don't want to
reboot or umount /home. Is it possible? Server is running with this
issue over one week without any other problems.

Thanks, rajo
