Doc Text:	In the previous net-snmp updates, the implementation of “HOST-RESOURCES-MIB::hrStorageTable” was rewritten and devices with Virtuozzo File System (VZFS) and BTRFS were not reported. In this update, snmpd properly recognizes VZFS and BTRFS devices and reports them in “HOST-RESOURCES-MIB::hrStorageTable”.	Story Points:	---

Description Andreas Schnederle-Wagner 2013-07-29 11:42:55 UTC

Description of problem:
   On RHEL 6.x with default net-snmp package I can't get hrStorage Data with SNMP. So no monitoring of diskspace with nagios/icinga/... is possible.
   It worked on older RHEL 4.x/5.x Version - but also not on the few latest Versions.
   I guess this Bug is related to: https://bugzilla.redhat.com/show_bug.cgi?id=861152

Version-Release number of selected component (if applicable):
   net-snmp-5.5-44.el6_4.2.x86_64

How reproducible:
Query on not working 6.4 Host:
   snmpwalk -v 2c -c public HOST hrStorage
Answer:
   HOST-RESOURCES-MIB::hrStorageType.1 = OID: HOST-RESOURCES-TYPES::hrStorageRam
   HOST-RESOURCES-MIB::hrStorageType.3 = OID: HOST-RESOURCES-TYPES::hrStorageVirtualMemory
   HOST-RESOURCES-MIB::hrStorageType.6 = OID: HOST-RESOURCES-TYPES::hrStorageOther
   HOST-RESOURCES-MIB::hrStorageType.7 = OID: HOST-RESOURCES-TYPES::hrStorageOther
   HOST-RESOURCES-MIB::hrStorageType.10 = OID: HOST-RESOURCES-TYPES::hrStorageVirtualMemory

Query on working 4.9 Host: 
   snmpwalk -v 2c -c public HOST hrStorage
Answer:
   HOST-RESOURCES-MIB::hrStorageType.1 = OID: HOST-RESOURCES-TYPES::hrStorageOther
   HOST-RESOURCES-MIB::hrStorageType.2 = OID: HOST-RESOURCES-TYPES::hrStorageRam
   HOST-RESOURCES-MIB::hrStorageType.3 = OID: HOST-RESOURCES-TYPES::hrStorageVirtualMemory
   HOST-RESOURCES-MIB::hrStorageType.4 = OID: HOST-RESOURCES-TYPES::hrStorageFixedDisk
   HOST-RESOURCES-MIB::hrStorageType.5 = OID: HOST-RESOURCES-TYPES::hrStorageFixedDisk
   HOST-RESOURCES-MIB::hrStorageType.6 = OID: HOST-RESOURCES-TYPES::hrStorageFixedDisk

Additional info:
   hrStorageFixedDisk is missing on current RHEL Versions

   Bug was introduced in RHEL 5.7
