Add Docs around multipath (MPIO) #11

Open maxirus opened 3 years ago

maxirus commented 3 years ago

I believe Multipath (MPIO) in iSCSI is only supported if A) you have multiple physical subnets and B) TrueNAS NICs are setup to utilize it.

It would be good to mention that by default multipath is (apparently) enabled by default in Debian based distros and needs to be disabled if the Target/Network does not support it.

Steps: Create dir: mkdir -p /etc/multipath/conf.d vi/nano /etc/multipath/conf.d/multipath.conf and add following:

defaults {
    find_multipaths "no"
}

Can test that volumes are mounted using multipath -ll command
