zfs discuss - Sep 2006 - create ZFS pool(s)/volume(s) during jumpstart instalation

Anyone have idea how to create ZFS pool and volumes during jumstart
instalation ? (I''m using JumpStart Enterprise Toolkit)

Right now, your only option is to use the zpool and zfs
commands from within a finish script.

Support for direct creation of zfs pools and datasets
using jumpstart profile keywords is coming with
zfs boot support.

Problem is with one thing: on jumpstart installation all installed
volumes are mounted in /a directory hierarchy and zfs mountpoints are
not stored in vfstab.
It is possible to install system but whole install procedure must be
done in two steps:
1) on prepare resources for installed system zfs volumes must be created
   with additional /a mountpoint prefixes,
2) after finish install packages and apply patches all zfs volumes must
   be remounted to production paths (without /a prefix).

As you wrote second step can be performed on finish script but I don''t
know how/where to hook first. In my case I want have /var and /exports
on common zfs pool.

PS. anyone know is it possible specify in host template perform
automatically reboot after finish install ? (I can''t find this)

1. in case of /var it would be probably better right now to actually
set legacy mounting and put it in a vfstab if you really want /var on
ZFS. Here (on the list) was posted before a procedure on how to
convert / to ZFS. If it''s a production server I would strongly wait
till ZFS root bits are integrated.

On the other hand I think it''s good to just install system on UFS and
then perhaps make a large pool from the rest of the disks and put a
zone on top of it. Then put an application into a zone.

That way you have ZFS.

2. to get system rebooted after jumpstarted just put in a finish script
sync;reboot
    I''m not sure but there''s some kind of variable you can
setup to get it reboot itself.

Hello,
>From a couple of tests I''ve done (not totally finished yet!), you
should look at zpool -R /a option to create zfs pool under /a from a finish
script. The mountpoint attribute will be relative to /a.
I''ve done something like when in mini-root (llaunch a ksh from a finish
to interactively try things):

zpool create -f -R /a myzfspool mirror c0t0d0s5 c0t2d0s5

Then I did a

zfs create myzfspool/opt
zfs set automountpoint=/opt myzfspool/opt

Then, I did

zpool export myzfspool

After, I wrote a script in /a/etc/rcS.d/S10zfs that is simply:
#!/usr/bin/ksh
#
case $1 in
  start)
        /sbin/zpool import -f myzfspool
        ;;

esac

I rebooted and I get this:

Hope this helps...
