Hi
I have a big storage to monitor in the redhat OS

Linux sgsnoasindd04lx-priv 2.6.32-642.13.1.el6.x86_64 #1 SMP Wed Nov 23 16:03:01 EST 2016 x86_64 x86_64 x86_64 GNU/Linux

./check_snmp_storage -H 10.205.139.35 -S0,1 -C SGS-MGMT-01 -m / -q FixedDisk -o 2000 -w 95 -c 98
CRITICAL : (>98%) /netapp/lun02: 261%used(7496464MB/2876126MB) /netapp/lun01: 254%used(7299876MB/2875841MB)

The check tell me that the 261% is used (IS WRONG)

Using df -k command , on the sistem , I can see

/dev/mapper/netapp01p1 ext4 11534795648 7475072648 3473782164 69% /netapp/lun01
/dev/mapper/netapp02p1 ext4 11535087472 7676379484 3272752356 71% /netapp/lun02

Please some one could help me to solve the check problem ?
Thanks

There's a known issue with the HOST-RESOURCES-MIB module which leads to integer overflow when handling large block counts.

Try including these in your remote system's /etc/snmp/snmpd.conf:
Then do a service snmpd restart to apply the changes.

If that doesn't work, I made some alterations to the original plugin to leverage a different set of OIDS. You might give it a shot:

The solution WORK !!!
