Slow iSCSI discovery on boot halting the boot process.

[Andrea Brancatelli]

Hello,  

I'm having an annoying problem with FreeBSD 12.2-RELEASE-p6, iscsid,
geom multiparty, a Dell MD3200i and fstab. 

Long story short, iSCSI login/connection/whatever is slower than the
boot process and the machine always get stuck with "cannot find
/san_storage (/dev/multipath/...) please enter /bin/sh location"  

Usually we just press enter, press control-d, and the boot process
continues. 

The problem is that the machine cannot boot unattended. 

Those are some cfg files: 

[root at arsenico ~]# cat /etc/fstab
# Device Mountpoint FStype Options Dump Pass#
/dev/mirror/gm0s1a / ufs rw 1 1
/dev/mirror/gm0s1b none swap sw 0 0
md98 none swap sw,file=/usr/swap1,late 0 0
md99 none swap sw,file=/usr/swap0,late 0 0
/dev/mirror/gm0s1d /var ufs rw 2 2
/dev/mirror/gm0s1e /tmp ufs rw 2 2
/dev/mirror/gm0s1f /usr ufs rw 2 2
/dev/mirror/gm0s1g /repository ufs rw 2 2
fdesc /dev/fd fdescfs rw 0 0
/dev/multipath/Krypton /san_storage ufs rw,late 0 0 

As you see the filesystem is already flagged as "late"... 

[root at arsenico ~]# cat /etc/iscsi.conf 

Krypton_C0_P0 {
TargetName=iqn.1984-05.com.dell:powervault.md3200i.6782bcb0007496a2000000004f1e49ee
TargetAddress=10.40.3.200
} 

That's the SAN, we dropped the dual connection so maybe we could get rid
of geom_multipath if that is the problem, but... hey...

Any interesting suggestions? 

Thanks a lot.
