Hi Team, I've put a bug in Github a few weeks back without fully understanding it. At first I thought it was config, or related to NVME drives however it turns out net-snmp does not recognise the F2FS partition format.
A very basic example of this is on one of my servers that have a rootfs with btrfs, and a mount "/cache" as f2fs: Filesystem Size Used Avail Use% Mounted on /dev/nvme0n1p3 451G 6.7G 444G 2% / /dev/sda1 3.8T 1.4T 2.5T 36% /cache My /etc/snmp/snmpd.conf is also basic: rocommunity public disk / disk /cache/ Yet a walk cannot see the F2FS partition/mount snmpwalk -v 2c -c public localhost dsktable UCD-SNMP-MIB::dskIndex.1 = INTEGER: 1 UCD-SNMP-MIB::dskPath.1 = STRING: / UCD-SNMP-MIB::dskDevice.1 = STRING: /dev/nvme0n1p3 UCD-SNMP-MIB::dskMinimum.1 = INTEGER: 100000 UCD-SNMP-MIB::dskMinPercent.1 = INTEGER: -1 UCD-SNMP-MIB::dskTotal.1 = INTEGER: 472268800 UCD-SNMP-MIB::dskAvail.1 = INTEGER: 464625932 UCD-SNMP-MIB::dskUsed.1 = INTEGER: 6968036 UCD-SNMP-MIB::dskPercent.1 = INTEGER: 1 UCD-SNMP-MIB::dskPercentNode.1 = INTEGER: 0 UCD-SNMP-MIB::dskTotalLow.1 = Gauge32: 472268800 UCD-SNMP-MIB::dskTotalHigh.1 = Gauge32: 0 UCD-SNMP-MIB::dskAvailLow.1 = Gauge32: 464625932 UCD-SNMP-MIB::dskAvailHigh.1 = Gauge32: 0 UCD-SNMP-MIB::dskUsedLow.1 = Gauge32: 6968036 UCD-SNMP-MIB::dskUsedHigh.1 = Gauge32: 0 UCD-SNMP-MIB::dskErrorFlag.1 = INTEGER: noError(0) UCD-SNMP-MIB::dskErrorMsg.1 = STRING: We are rolling out F2FS on all of our flash-enabled systems (which enables significant performance and durability improvements on Flash media) and need assistance resolving this bug so we can resume monitoring of these partitions. Thanks, Greg
