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? -Heinrich
