Hello Zabbix Team,

I'm trying to monitor some disk partitions and I'm getting ZBX_NOTSUPPORTED.

My mount points are set like so:

/dev/mapper/vg-media on /media 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)
/dev/mapper/vg-alta_2011_03 on /media/fotografia/alta/2011/03 type ext4 (rw,noatime,nodiratime)
/dev/mapper/vg-alta_2011_04 on /media/fotografia/alta/2011/04 type ext4 (rw,noatime,nodiratime)
/dev/mapper/vg-alta_2011_05 on /media/fotografia/alta/2011/05 type ext4 (rw,noatime,nodiratime)
