I just decided to revisit this, and unfortunatly, I'm still stuck with the loader having trouble reading blocks off the raidz1 volume. I've updated the creation script (see below). This is on r195709, with LOADER_ZFS_SUPPORT?=YES in /etc/make.conf. Boot output, transcribed by hand: error 4 lba 4290782259 error 4 lba 4290782258 error 4 lba 4290782259 error 4 lba 4290782258 error 4 lba 4290782257 error 4 lba 4290782257 ... error 4 lba 4292652987 error 4 lba 4292652986 error 4 lba 4292652987 BTX loader 1.00 BTX version is 1.02 Consoles: internal video/keyboard BIOS drive A: is disk0 BIOS drive C: is disk1 BIOS drive D: is disk2 BIOS drive E: is disk3 BIOS 638kB/2095040kB available memory FreeBSD/i386 bootstrap loader, Revision 1.1 (root@freebsd-current-lassitu.de, Wed Jul 15 19:31.22 CEST 2009) Loading /boot/defaults/loader.conf ZFS: i/o error - all block copies unavailable ZFS: i/o error - all block copies unavailable ...
