Why does the first and last commands return valid data and the second one doesn't?

Here is a part of the mounts on the monitored machine that might help:

/dev/mapper/vg-fotografia_alta on /media/fotografia/alta type ext4 (rw,noatime,nodiratime)
/dev/mapper/vg-alta_2009 on /media/fotografia/alta/2009 type ext4 (rw,noatime,nodiratime)
/dev/mapper/vg-alta_2010 on /media/fotografia/alta/2010 type ext4 (rw,noatime,nodiratime)
/dev/mapper/vg-alta_2011_01 on /media/fotografia/alta/2011/01 type ext4 (rw,noatime,nodiratime)
/dev/mapper/vg-alta_2011_02 on /media/fotografia/alta/2011/02 type ext4 (rw,noatime,nodiratime)

Please let me know if there is any extra info necessary.

du output

The only errors I received from those commands where related to 'lost+found'
directories.


$cd cd /media/fotografia/alta/2011/

Allow root

I forgot to mention that the Zabbix Client configuration is set to allow root. So I don't think that could be permission problem.

zabbix_agentd.conf:AllowRoot=1

Updated

After updating both, server and client to v1.8.6 (revision 20932), the problem persists.

udpate

From the client I always get the right results. But when I try from the server
it returns the ZBX_NOTSUPPORTED message.

client # zabbix_agentd -t 'vfs.fs.size[/media/fotografia/alta/2011/01]'
vfs.fs.size[/media/fotografia/alta/2011/01] [u|164875579392]

client # zabbix_agentd -t 'vfs.fs.size[/media/fotografia/alta/2011/]'
vfs.fs.size[/media/fotografia/alta/2011/] [u|499910975488]


server $ zabbix_get -s CLIENT -p10050 -k 'vfs.fs.size[/media/fotografia/alta/2011/]'
