Yes, i have tried. I did get a flurry of information, but nothing =
related to the kernel not being able to mount the root fs.
In the meanwhile, i have redone the installation and for some reason it =
is working now. Probably the pool cache was missing.. :-)

Now i have another problem:

The root fs on on a 4-disk zfs mirror. I am testing under VMware fusion =
using virtual scsi disks. In order to test redundancy, i removed the =
first disk and booting failed. The loader reports:

error 1 lba 32
error 1 lba 1
error 1 lba 32
error 1 lba 1
error 1 lba 32
error 1 lba 1
error 1 lba 32
error 1 lba 1
No ZFS pools located, can't boot

If i remove any other of the 3 disks instead, booting works fine. Is the =
pool's configuration only stored on the first disk? Do i have to =
replicate it to the other disks by hand?
