RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

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.
