I started to check the new ZFS version inside a VirtualBox machine. So far
it works for me without crashes, but I got some observations worth
mentioning. Here are the steps I made:
1. Installed 8.1-RELEASE (from minimal install CD)
2. Csup'ped sources to CURRENT (as of 14/12/2010) [note that I haven't
used SVN repository]
3. Applied the patch in question.
4. Created a zpool raidz of two disks of old version 15. Also some usual
tuning of ZFS in loader.conf was done as I am running 32 bit version with
low amount of memory. "zfs_enable=YES" in rc.conf was added too.
4.1 Moved /usr/ports to ZFS to have some files on it.
5. Make buildworld, buildkernel, installkernel, installworld - all the
canonical steps from the Handbook.
6. After reboot to final 9.0-CURRENT world I got a dmesg with some trace
stack related to ZFS and also a rc.d script message about unrecognized
command 'volinit' (see the text of it in attachment).
7. Nevertheless the system booted. Files
8. `zpool upgrade -a` worked all right and reported that now I have ZFS
version 28
Overall I am pleasantly surprised how streamlined the whole process was.
I am going to perform more tourturing of this VM later as well.
Thanks for your work!
