Dave made a mistake pulling out the drives with out exporting them first.
For sure also UFS/XFS/EXT4/.. doesn't like that kind of operations but only
with ZFS you risk to loose ALL your data.
that's the point!

I did that many times after performing the umount cmd with ufs/reiserfs
filesystems on USB external drives. And they never complainted or got corrupted.
Possibly so. But if you had that ufs/reiserfs on a LVM or on a RAID0
spanning removable drives, you probably wouldn't have been so lucky.
Just because you only create a single ZFS filesystem inside your zpool,
doesn't mean that when that single filesystem is unmounted it si safe to
remove the drive. When you consider the extra layer of the zPool (like
LVM or sw RAID) it's not surpriseing there are other things you have to
do before you remove the disk.
