Notice this says s8 for the last two slice numbers. It's also using s2 for the second disk, but s2 is typcally the entire disk anyway, so it's able to see all the data. On the other hand, s8 is typically just the first cylinder -- just enough information for zfs to see the front labels, but not enough to see all the data. zfs should probably be better about what it chooses for a disk to import. A coworker suggests looking at the zdb -l output, fdisk output, and prtvtoc output to see if there's a common theme that will lead to a solution independent of modifying zfs import code.

My pool, using p0 devices, does currently mount at boot. This is using the
p0 devices in /dev/dsk, not symlinks in a directory (those have been
deleted).
This does seem like it might indicate that importing the devices changed
something on disk - I'm not sure what, but something that has caused it to
know that it should use the p0 devices rather than s2 or s8. I have no idea
whether this would affect ability to import in BSD. It does not seem like it
should, intuitively, but I don't have much basis in actual knowledge of the
inner workings to say that - you shouldn't take my word for it.
As for partition tables, everything seems to be working happily without
them. I'd still like to know from somebody more knowledgeable about what I
might lose, not having them, but I haven't run into any issues yet.

I have read your thread now ("Help with corrupted pool" for anyone
interested). It raised some questions in my head... Someone wrote that
this method "will not work at boot"? Does that mean that the pool
won't automount at boot or that I can't boot from it (that one I don't
mind)?
Also, if I import the pool successfully in OpenSolaris (and don't do
zfs/zpool upgrade), will that destroy my chances of importing it in
FreeBSD again in the (near) future?
I haven't tried importing because I'm not yet ready to make the switch
to OpenSolaris, I need to replace a controller (Promise PDC40518
SATA150 TX4) that isn't recognized, but that's another issue.
I too would want an answer to "Is there any significant advantage to
having a partition table?", but seeing that your last post is pretty
new, maybe that will come.
Thanks for the help.

Re: [zfs-discuss] Import zpool from FreeBSD in OpenSolaris
When i needed to do this, the only way i could get it to work was to do this: Take some disks, use a Opensolaris Live CD and label them EFI Create a ZPOOL in FreeBSD with these disks copy my data from freebsd to the new zpool export the pool import the pool On Tue, Feb 23, 2010 at 9:11 PM, patrik wrote: > I want to import my zpool's from FreeBSD 8.0 in OpenSolaris 2009.06. > > After reading the few posts (links below) I was able to find on the > subject, it seems like it there is a differences between FreeBSD and > Solaris.
