Why SNMP Daemon does not report Disk Used Percent Inodes after upgrading to RHEL 5.7?

Issue

• The UCD-SNMP-MIB consist of dskPercent (Used Space in percent) and dskPercentNode (Used Inodes in Percent).

• After upgrading to RHEL5.7, die UCD-SNMP-MIB Reports all dskPercentNode with INTEGER: -1

• Therefore, SNMP Daemon does not report Disk Used Percent Inodes.
