Hello Sir, I am trying to install FreeBSD Sparc64 on my machine, I followed the tutorials to Install FreeBSD Root on ZFS(tutorial link ) <https://wiki.freebsd.org/RootOnZFS/VTOC8ZFSBoot/9.x-RELEASE>. Only the changes I made is that instead of using mirror I tried configuring raidz with four internal disks and added bootloader in all the disks (da0 da1 da2 da3). Everything was fine while installing but booting after installation shows the error below:- |ZFS: i/o error - all block copies unavailable ZFS: can't read MOS object directory ZFS: can't find root filesystem FreeBSD/sparc64 ZFS enabled bootstrap loader, Revision 1.0 (root@releng1.nyi.freebsd.org, Wed Nov 12 03:13:59 UTC 2014) bootpath="" can't load 'kernel' | I created zpool like this:- zpool create -f -o altroot=/mnt -O canmount=off zroot raidz da0a da1a da2a da3a here is my bootloader installation:- # zpool export zroot # gpart bootcode -p /boot/zfsboot da0 # gpart bootcode -p /boot/zfsboot da1 # gpart bootcode -p /boot/zfsboot da2 # gpart bootcode -p /boot/zfsboot da3 # sysctl kern.geom.debugflags=0x10 kern.geom.debugflags: 0 -> 16 # dd if=/boot/zfsloader of=/dev/da0a bs=512 oseek=1024 conv=notrunc,sync # dd if=/boot/zfsloader of=/dev/da1a bs=512 oseek=1024 conv=notrunc,sync # dd if=/boot/zfsloader of=/dev/da2a bs=512 oseek=1024 conv=notrunc,sync # dd if=/boot/zfsloader of=/dev/da3a bs=512 oseek=1024 conv=notrunc,sync # zpool import -o altroot=/mnt zroot Any ideas?
