Hi,
	I guess I am misunderstanding it. The ctl.conf is on 2 different
servers, so they are two different disks.

What I am hoping to achieve is sort of like a HAST setup. So that if
server-a dies, server-b takes over

So on server a) I did

zfs create -V 80G zroot/v1

and on server b) I did

zfs create -V 80G tank1/v1


However, in order for the files to be identical, I used the slower disks
on b) so that the path statement is identical. But should this matter ?


a)
# cat /etc/ctl.conf
debug 1
portal-group pg0 {
    discovery-auth-group no-authentication
    listen 192.168.242.6
    listen 192.168.79.1
}

target iqn.2018-01.ca.sentexcloud1:target0 {
    auth-group no-authentication
    portal-group pg0

    lun 1 {
            backend block
            path /dev/zvol/tank1/v2
            blocksize 4096
            device-id MULTI
            serial 20180423
    }
}

b)

# cat /etc/ctl.conf
    debug 1
portal-group pg0 {
    discovery-auth-group no-authentication
    listen 192.168.79.2
    listen 192.168.242.11
}

target iqn.2018-01.ca.sentexcloud1:target0 {
    auth-group no-authentication
    portal-group pg0

    lun 1 {
            backend block
            path /dev/zvol/zroot/v2
            blocksize 4096
            device-id MULTI
            serial 20180423
    }
}
