ZBX_NOTSUPPORTED on one system, but not another.

[ptader]

Two identical systems (hardware and OS, RHEL4). Trying to monitor free space on these file systems:

/dev/sdc 8.2T 6.1T 2.1T 75% /storage/data1
/dev/sdd 8.2T 6.1T 2.2T 75% /storage/data2
/dev/sde 8.2T 6.1T 2.2T 75% /storage/data3
/dev/sdf 8.2T 6.2T 2.1T 75% /storage/data4

(/etc/fstab)
/dev/sdc on /storage/data1 type xfs (rw)
/dev/sdd on /storage/data2 type xfs (rw)
/dev/sde on /storage/data3 type xfs (rw)
/dev/sdf on /storage/data4 type xfs (rw)

...the key I'm using:
vfs.fs.size[/storage/data1,free]

On one system the items turn to "Not Supported" but the other system it reports back fine. Checked permissions and client version (1.4.4).

# zabbix_get -s system1 -k vfs.fs.size[/storage/data3,free]
ZBX_NOTSUPPORTED

# zabbix_get -s system2 -k vfs.fs.size[/storage/data3,free]
703398716

I turned verbose on the failing client and see this in the log:

20063:20080821:142147 Processing request.
20063:20080821:142147 In check_security()
20063:20080821:142147 Requested [vfs.fs.size[/storage/data3,free]]
20063:20080821:142147 Sending back [ZBX_NOTSUPPORTED]

All other checks are running fine including other filesystem checks. Any other troubleshooting tips?
