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
Also confirmed, this remains broken in 12.04
$ snmpwalk -v2c -c public storage3 hrStorageTable | grep
\\.34HOST-RESOURCES-MIB::hrStorageIndex.34 = INTEGER: 34
HOST-RESOURCES-MIB::hrStorageType.34 = OID:
HOST-RESOURCES-TYPES::hrStorageFixedDisk
HOST-RESOURCES-MIB::hrStorageDescr.34 = STRING: /dis
I can confirm this is not fixed. I'm still having the issue on 12.04.

Looks like it could be related to this:
https://bugzilla.redhat.com/show_bug.cgi?id=654384
Apparently a newer snmpd would clamp this value to 2^31, and an even newer
snmpd would use a fake larger block size so as to be able to report on large
filesystems:
