Description Romain LE DISEZ 2012-09-27 16:10:54 UTC 
On RHEL 6.3, with the default net-snmp package (net-snmp 1:5.5-41.el6_3.1), I can't get the root partition of an OpenVZ container via SNMP. This bug makes the monitoring of diskspace impossible.

>>>>>>>>>>>>>>>>>>>>>>>
# snmpwalk  -v 2c -c public  server.example.com  hrStorageDescr
HOST-RESOURCES-MIB::hrStorageDescr.1 = STRING: Physical memory
HOST-RESOURCES-MIB::hrStorageDescr.3 = STRING: Virtual memory
HOST-RESOURCES-MIB::hrStorageDescr.6 = STRING: Memory buffers
HOST-RESOURCES-MIB::hrStorageDescr.7 = STRING: Cached memory
HOST-RESOURCES-MIB::hrStorageDescr.10 = STRING: Swap space
<<<<<<<<<<<<<<<<<<<<<<<


If I recompile the SRPM after I disabled the application of Patch23: net-snmp-5.5-hrFSTable-indexes.patch in the SPEC file, everything works fine, I can monitor the diskspace.

>>>>>>>>>>>>>>>>>>>>>>>
# snmpwalk  -v 2c -c public  server.example.com  hrStorageDescr
HOST-RESOURCES-MIB::hrStorageDescr.1 = STRING: Physical memory
HOST-RESOURCES-MIB::hrStorageDescr.3 = STRING: Virtual memory
HOST-RESOURCES-MIB::hrStorageDescr.6 = STRING: Memory buffers
HOST-RESOURCES-MIB::hrStorageDescr.7 = STRING: Cached memory
HOST-RESOURCES-MIB::hrStorageDescr.10 = STRING: Swap space
HOST-RESOURCES-MIB::hrStorageDescr.31 = STRING: /
<<<<<<<<<<<<<<<<<<<<<<<

(the following does not apply anymore when Patch23 is not applied)
Patch30: net-snmp-5.5-gfs.patch
Patch46: net-snmp-5.5-xfs.patch
Patch61: net-snmp-5.5-hrStorage-realStorageUnits.patch
Patch62: net-snmp-5.5-hrStorage-realStorageUnits2.patch
Patch63: net-snmp-5.5-hrStorage-fs.patch


This bug appeared in RHEL 5.7

I am a user of CentOS, the problem is also in Fedora. I hadn't tested on RHEL but I'm pretty sure it has the same bug.

Add support for simfs

I'm not an net-snmp expert, but this patch works for me. I just used the one for XFS as a base.
