/devices/pseudo/bitbucket@0:bitbucket: Musings from the bitbucket

There's currently no way to do an in-place upgrade0 from Solaris Express's SysV packaging to OpenSolaris' IPS packaging, so you have to think outside the box just a little.

My Ultra 40 M2 has been happily chugging away with SXCE builds since I took delivery of it, but with build 131 fast approaching (when we start delivering a nightly IPS repo rather than SysV packages), I figured I should put some effort into migrating to the new world. Fortunately for me, I've been running with ZFS root since it was first available (build 80 or so), and when I reinstalled my laptop last year I put OpenSolaris on it. It's been upgraded to snv_126 in the last week, too.

Here's what I did.


After making sure I had enough space in my u40m2 ("blinder") root pool, I created a zfs snapshot of the current BE on the laptop ("gedanken"). Then destroyed it, pruned sundry filesystems and a bunch of packages which I don't need (eg, I have no use for almost all the localisations), and re-created the snapshot.

gedanken# zfs snapshot rpool/ROOT/opensolaris-7@yay
blinder# zfs create rpool/ROOT/opensolaris-7

Then I sent it from gedanken to blinder:

gedanken# zfs send rpool/ROOT/opensolaris-7@yay | \
    ssh blinder zfs recv -v rpool/ROOT/opensolaris-7

[trundle]

received 20.8GB stream in 2707 seconds (7.85MB/sec)

Now the action switches to blinder:

(add entry to grub menu.lst, remember to set the default)

# zpool set boots=rpool/ROOT/opensolaris-7 rpool
# zfs set canmount=noauto rpool/ROOT/opensolaris-7
# zfs set mountpoint=/ rpool/ROOT/opensolaris-7

Time for some customisations on the new pool:

# zfs set mountpoint=/mnt rpool/ROOT/opensolaris-7
# cp /etc/ssh/sshd*key* /mnt/etc/ssh
# cp /etc/hostid /mnt/etc/hostid
# cp /etc/inet/hosts /mnt/etc/inet/hosts
# cp /etc/X11/xorg.conf /mnt/etc/X11
# cp /etc/hostname.nge0 /mnt/etc
# cp /var/spool/cron/cronjobs/onhg /mnt/var/spool/cron/cronjobs

I think that's it, I really should have run this from within script(1)!

# cd /
# zfs umount rpool/ROOT/opensolaris-7
# zfs set mountpoint=/ rpool/ROOT/opensolaris-7

Time for the acid test!

# init 6

[dammit, this "fast reboot" stuff is TOO FAST!]

and X came up just fine.

After making sure that all the bits that I expected were there, I was very pleased to call this exercise a success.

The only bit that remains to be done is configuring my non-global zone but I'll leave that for another post.
