What is zpoolSize?

The total capacity of this ZFS pool, expressed as a count of the allocation units set in zpoolAllocationUnits; this is the pool's raw usable size before subtracting used space.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.50536.1.1.1.1.4
snmpwalk -v2c -c public <target> FREENAS-MIB::zpoolSize

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.50536.1.1.1.1.4.1
snmpget -v2c -c public <target> FREENAS-MIB::zpoolSize.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.50536.1.1.1.1.4.1 i <value>

SNMPv3 example:

snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> zpoolSize.1
