Older version simply don't have the support for the higher capacities, so upgrading to a newer version is the only option. I have no knowledge of RHEL maintenance and repositories so I can't offer help in that regard...

Latest Debian stable luckily has it, before that I had my own package backported to fix this on servers with  larger capacity. :-) 5.7 also helps with actual speeds of bonds and such instead of 10Mbps :-)

Sorry regarding the hijack. I thought I had created a new message and copied the list address into it. 


Thank you, and yes Redhat uses a rather old net-snmp.

Hi Rhian,

First off, please don't hijack threads - this has nothing to do with mod_auth_kerb.

Second, yes, you need an snmpd supporting the high capacity storage tables. Net-SNMP supports this from 5.7 on, if you don't disable if via compile options, so an upgrade might be in order.

Good morning,


We recently noticed that SNMP is having difficulty handling large file sysystem. We have a 120TB XFS system that is reporting on 4.4TB and alerting because SNMP is reporting the wrong values. 


snmpwalk -mALL -v2c -{COM} {HOST} hrStorageTable  | grep 40
HOST-RESOURCES-MIB::hrStorageIndex.40 = INTEGER: 40
HOST-RESOURCES-MIB::hrStorageType.40 = OID: HOST-RESOURCES-TYPES::hrStorageFixedDisk
HOST-RESOURCES-MIB::hrStorageDescr.40 = STRING: /home
HOST-RESOURCES-MIB::hrStorageAllocationUnits.40 = INTEGER: 4096 Bytes
HOST-RESOURCES-MIB::hrStorageSize.40 = INTEGER: 1186465536
HOST-RESOURCES-MIB::hrStorageUsed.40 = INTEGER: 1036605829
HOST-RESOURCES-MIB::hrStorageUsed.44 = INTEGER: 666446640

Some forums have indicated this can be resolved by upgrading to 64 bit integers but I am not an SNMP expert. 


Has anyone seen this behavior and if so how do we work around it?  In the HPC world this is a small name space so I worry about monitoring storage on our Lustre FS.


Thanks
