Doc Text:
In the previous net-snmp update, implementation of the UCD-SNMP-MIB::dskTable table was rewritten and reporting of the UCD-SNMP-MIB::dskPercentNode column was accidentally removed from the snmpd daemon. With this update, the object identifier for UCD-SNMP-MIB::dskPercentNode has been restored and it now properly reports percentages of used inodes on storage devices, thus fixing this bug.

Description Mario Heininger 2011-07-25 08:48:12 UTC 
Description of problem:

The UCD-SNMP-MIB Table has Fields for DskPercentNode (Used Inodes in Percent), after Upgrade to net-snmp-5.3.2.2-9.el5_5.1 the Field isn't reported any more.


Version-Release number of selected component (if applicable):
net-snmp-5.3.2.2-9.el5_5.1

How reproducible:
Install net-snmp from RHEL5.6 Tree , DskPercentNode is reported, update to RHEL5.7 Tree, DskPercentNode list only -1 on all Devices.



Steps to Reproduce:
1. Install RHEL5.6 NET-SNMP

2. snmpwalk the ucd-snmp-mib
# snmpwalk -v2c -cXXXXXX 127.0.0.1 .1.3.6.1.4.1.2021.9 | grep "dskPercentNode"
UCD-SNMP-MIB::dskPercentNode.1 = INTEGER: 13
UCD-SNMP-MIB::dskPercentNode.2 = INTEGER: 2
UCD-SNMP-MIB::dskPercentNode.3 = INTEGER: 27


3. Upgrade to RHEL5.7 NET-SNMP

4. snmpwalk again the ucd-snmp-mib
# snmpwalk -v2c -cXXXXXX 127.0.0.1 .1.3.6.1.4.1.2021.9 | grep "dskPercentNode"
UCD-SNMP-MIB::dskPercentNode.1 = INTEGER: -1
UCD-SNMP-MIB::dskPercentNode.2 = INTEGER: -1
UCD-SNMP-MIB::dskPercentNode.3 = INTEGER: -1

After Codeview i found that the net-snmp-5.3.2.2-dskTable-64.patch removes the "inode" Sections in the Sourcecode.

a fix

I forgot to rename some macro names when backporting newer dskTable from upstream.

Hello Jan,

thank you, i have tested the patch with an recompile of the Red Hat Package. The Patch works, inode in usd-snmp-mib works.

Bye Mario
