FREEBSD SCRAPS

08:21 <+stgraber> feurig: I believe I made a video about it an MAAS some time ago
08:21 <+stgraber> feurig: anyway, it's basically:
08:22 <+stgraber> lxc init my-pxe --empty --vm
08:22 <+stgraber> lxc config device override my-pxe eth0 boot.priority=10
08:22 <+stgraber> lxc start my-pxe --console=vga
08:22 <+stgraber> the boot.priority step is to have QEMU prefer network boot over local disk
08:23 <+stgraber> you may also want to grow the root disk depending on your needs: lxc config device override my-pxe root size=50GiB

pure config is out of scope of this note

setting up pure -> freebsd

/etc/rc.conf.local

iscsid_enable="YES" iscsictl_enable="YES" iscsictl_flags="-Aa"

grab rc.d file from zfs-backup2:/etc/rc.d/zpool_iscsi

so system will try to import zpool after iscsi has settled

zpool_iscsi_enable="YES"

/etc/iscsi.conf

pure01-ct0-1 { TargetAddress = pure01-ct0-1.evergreen.laika.com SessionType = Discovery InitiatorName = iqn.2005-06.com.laika:freebsd-hostname.evergreen.laika.com } pure01-ct0-2 { TargetAddress = pure01-ct0-2.evergreen.laika.com SessionType = Discovery InitiatorName = iqn.2005-06.com.laika:freebsd-hostname.evergreen.laika.com } pure01-ct1-1 { TargetAddress = pure01-ct1-1.evergreen.laika.com SessionType = Discovery InitiatorName = iqn.2005-06.com.laika:freebsd-hostname.evergreen.laika.com } pure01-ct1-2 { TargetAddress = pure01-ct1-2.evergreen.laika.com SessionType = Discovery InitiatorName = iqn.2005-06.com.laika:freebsd-hostname.evergreen.laika.com }

service iscsid start service iscsictl start

view iscsi luns

iscsictl -L

remove luns

iscsictl -Ra

add luns

icsictl -Aa

freebsd initiator doesn't handle multipath.

The geom_multipath kernel module does

create multipath device

kldload geom_multipath

make it survive a reboot

echo geom_multipath_load="YES" >> /boot/loader.conf

gmultipath label mp0 da4 da5 da6 da7

now you can create a zpool using the mp0 device

zpool create zjail multipath/mp0 zfs set mountpoint=/jails zjail zpool set autotrim=on zroot zfs set compression=off zjail
