Now I can't boot into single user mode anymore, ZFS just waits forever, and the kernel is printing an endless chain of SATA error messages. I really need a way to remove the broken disk before ZFS tries to access it, or a way to stop ZFS from try to access the disk. Stefan -- Stefan Bethke <s...@lassitu.de> Fon +49 151 14070811
