[Bug 865268] Re: snmpd reports wrong value for hrStorageSize on large filesystem
Looking at the source of net-snmp-5.4.3~dfsg, it appears to make no attempt to scale the block size to avoid 2^32 wrapping - see agent/mibgroup/host/hr_storage.c, var_hrstore() I have made a simple patch which fixes just this particular problem, so should be suitable for backporting to LTS. Once this patch has been applied, sane values are returned: $ snmpwalk -v2c -c public storage3 hrStorageTable | grep '\.34 'HOST-RESOURCES-MIB::hrStorageIndex.34 = INTEGER: 34 HOST-RESOURCES-MIB::hrStorageType.34 = OID: HOST-RESOURCES-TYPES::hrStorageFixedDisk HOST-RESOURCES-MIB::hrStorageDescr.34 = STRING: /disk/scratch HOST-RESOURCES-MIB::hrStorageAllocationUnits.34 = INTEGER: 65536 Bytes HOST-RESOURCES-MIB::hrStorageSize.34 = INTEGER: 1098363146 HOST-RESOURCES-MIB::hrStorageUsed.34 = INTEGER: 1052804334 (Note: the agent modules are actually in libsnmp15, so after dpkg- buildpackage remember to install libsnmp15, libsnmp-base and snmpd) ** Patch added: hrStorage_large_filesystem.patch https://bugs.launchpad.net/ubuntu/+source/net-snmp/+bug/865268/+attachment/3412218/+files/hrStorage_large_filesystem.patch -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to net-snmp in Ubuntu. https://bugs.launchpad.net/bugs/865268 Title: snmpd reports wrong value for hrStorageSize on large filesystem To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/net-snmp/+bug/865268/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
