I've just installed a stable/10 kernel, specifically: 10.1-PRERELEASE FreeBSD 10.1-PRERELEASE #11 r271316M and booted fine from a mirrored root without issue: config: NAME STATE READ WRITE CKSUM tank ONLINE 0 0 0 mirror-0 ONLINE 0 0 0 ada0p3 ONLINE 0 0 0 ada2p3 ONLINE 0 0 0 gpart show ada0 ada2 => 34 250069613 ada0 GPT (119G) 34 128 1 freebsd-boot (64K) 162 8388608 2 freebsd-swap (4.0G) 8388770 241680877 3 freebsd-zfs (115G) => 40 586072288 ada2 GPT (279G) 40 128 1 freebsd-boot (64K) 168 8388608 2 freebsd-swap (4.0G) 8388776 577683552 3 freebsd-zfs (275G) I then detached the second disk so the machine had just: config: NAME STATE READ WRITE CKSUM tank ONLINE 0 0 0 ada0p3 ONLINE 0 0 0 Rebooted and again all fine no issues I've also got a raidz1 box on the same kernel it too is fine. => 34 500118125 ada0 GPT (238G) 34 128 1 freebsd-boot (64K) 162 500117997 2 freebsd-zfs (238G) ... So its seems like there's something odd about your environment, especially given you've had a similar issue before. So the questions: 1. What does zpool get all report? 2. What does /boot/loader.conf have in it? 3. What does zdb -C rdnzltank report? 4. What does /etc/rc.conf have in it? Regards Steve
